Abstract:

The classical European system based on the construction of transverse structures is very significant in the solving of the problems of deep and lateral erosion and sediment accumulation in torrent beds. However, due to their effective height on the upstream side, the dams check and accumulate the sediment making the siltation (deposition of silt) whose slope is called the slope of siltation. This paper presents the natural effects of transverse structures (dams) in Gabrova?ka reka, which can be quantified. The paper presents the effects of bed slope on the slopes of siltation and the amounts of accumulated sediment in the siltations, because the effects of technical works are primarily evaluated by the slopes of siltation and by the amounts of accumulated sediment. The analysis of the dependence of newly formed slopes of siltation (Iz) on natural bed slopes (It) was performed by the method of modeling, as the main method, and also by regression and correlation analyses (simple correlation), as concrete study methods. Under the hypothesis that the siltations have a regular wedge, i.e. prismatic form, the accumulated sediment W [m3] in the siltations was calculated by B. Kitin (1975) formula. The study results confirm the very high correlation between the slopes of siltation and bed slope and present the amounts of the accumulated sediment in the conditions of different natural bed slopes and valley widths. This is a useful information which can improve and make more efficient the work on torrent con1rol with similar orographic, petrographic and particle size characteristics.

Abstract:

This study constructs a digital elevation model of the coastal waters of the Shandong Peninsula using GIS-based interpolation methods to investigate the 15-year characteristics of seabed scouring and siltation. It utilizes depth data of the Shandong Peninsula’s offshore area between 2004 and 2006 and 2017 and 2019. The results indicated that the Shandong Peninsula’s coastal-water seabed is characterized by integral siltation and local point scouring. In addition, the northwest Shandong Peninsula is dominated by siltation, mainly distributed between 2 and 5 m isobaths, with the largest siltation area located in Laizhou Bay. The net volume of siltation is 2.13 × 108 m3, the siltation rate is 0.152 × 108 m3.a−1, and the scouring is concentrated in the estuary and the west coast of Laizhou Bay. Scouring and siltation balance generally characterize the seabed in the northern coastal waters of the Shandong Peninsula, and the degree of scouring and siltation is weak. The siltation occurs primarily near the land area, while scouring occurs as the sea deepens. In the northeast of the Shandong Peninsula, the degree of scouring and siltation is extreme, and their distribution range is small, whereas in the south, siltation is distributed in large bays and straight coastal offshore waters, and its degree is relatively weak. At the southernmost end of the study area, the scouring and siltation in Jiaozhou Bay are spatially distributed and balanced. In reality, the key factors affecting the distribution of coastal-seabed scouring and siltation are materials transported by river sediment, coastal scouring, and human activities.

Abstract:

Siltation involves the accumulation of sediment over a considerable period of time and this may occur in closed systems like leaching tanks. Most mining companies in Ghana experience siltation problems during leaching of gold ore. This paper examines the potential causes and possible mitigation measures of siltation. Particle size analysis, slurry settling rate tests and agitation efficiency analysis were used in identifying causative factors of siltation whiles deflocculation test and grind analysis were conducted to ascertain mitigation measures. Results from the study indicated that, high settling velocity of particles, inefficient milling and classification, poor slurry agitation and particle flocculation were the major causative factors leading to siltation. Size analysis results revealed P67 of 106 µm instead of P80 of 106 µm, a situation which affects particle suspension by agitators leading to siltation. This study therefore suggests that increase in milling residence time and particle deflocculation are potential remediation measures for curbing siltation. Extended grinding of ball mill feed resulted in 94% passing 106 µm while settling velocity was reduced by 71% after deflocculant addition at 1000 ppm. Keywords: Siltation, Deflloculation, Settling Velocity, Grinding

Abstract:

There are many reservoirs in China with serious siltation issues which are affecting the function and safety of the reservoirs. Recently, research studies have been carried out regarding siltation loss control and capacity recovery technology due to the decreases in suitable dam sites for establishing reservoirs, and the increasingly serious siltation losses which have been occurring in the present reservoirs. The results of these studies have been of great significance to the partial recoveries of the siltation capacities of reservoirs, improvements in the respective efficiencies of the current reservoirs, and the prolonging of the service life the reservoirs. This study presented a simple review of the previous research findings regarding the current siltation loss situations and controls, as well as the capacity recoveries which have been achieved. Also, this study proposed the urgent need for in-depth examinations to be conducted pertaining to the national investigations of the reservoir siltation status in China, as well as a review of the current mechanisms and control measures for reservoir siltation losses.

Abstract:

Aiming at the clogging problems encountered in the operation of deep-hole gates in high water level reservoirs and dams, this paper carried out a model test study on the influence of different materials and different siltation environments on the lifting of the gates and analyzed the rules of the effects of blockages in different siltation environments. An analysis model of the pull-out force of the gate (blocked object) considering the siltation environment was proposed in an innovative way and the similarity ratio relationship was verified. The results of the study show that (1) the size and time of the siltation and other factors have a significant influence on the pulling force of the blocked object. It increases with the increase of the siltation area. The longer the siltation goes on, the greater the pulling force will be. (2) As the similarity ratio n increases, the calculation result of the analysis model is closer to the target value n 2 and it indicates that the theoretical model is reliable. The research results of this paper can provide certain guidance for deep-hole siltation dispatch to ensure project safety.

Full text

Abstract:

Dams are vital for irrigation, power generation, and domestic water needs, but siltation poses a significant challenge, especially in areas prone to water erosion, potentially shortening a dam’s lifespan. The Ahmed El Hansali Dam in Morocco faces heightened siltation due to its upstream region being susceptible to erosion-prone rocks and high runoff. This study estimates the siltation at the dam from its construction up to 2014 using bathymetric data and the Brown model, which is a widely-used empirical model that calculates reservoir trap efficiency. Additionally, the study evaluates the impact of Land Use and Land Cover (LULC) changes and projected future rainfall until around 2076 based on siltation rates. The results indicate that changes in LULC, particularly temporal variations in precipitation, have a significant impact on the siltation of the Ahmed El Hansali dam. Notably, rainfall is strongly correlated with the siltation rate, with an R2 of 0.92. The efficiency of sediment trapping (TE) is 97.64%, meaning that 97.64% of the sediment in the catchment area is trapped or deposited at the bottom of the dam. The estimated annual specific sediment yield is about 32,345.79 tons/km2/yr, and the sediment accumulation rate is approximately 4.75 Mm3/yr. The dam’s half-life is estimated to be around 2076, but future precipitation projections may extend this timeframe due to the strong correlation between siltation and precipitation. Additionally, soil erosion driven by land management practices plays a crucial role in future siltation dynamics. Hence, this study offers a comprehensive assessment of the siltation dynamics at the Ahmed El Hansali dam, providing essential information on the long-term effects of erosion, land use changes, and climate projections. These findings may assist decision makers in managing dam reservoir sedimentation more effectively, ensuring the durability of the dam and extending the reservoir life.

Abstract:

Siltation in the rivers downstream of floodgates is serious in China, making the discharge capacity of rivers decrease obviously and threatening the flood control in upper rivers. Tidal wave deformation is one conclusive dynamic factor leading to siltation downstream of floodgates in estuaries. A 2-D numerical model of tide and sediment transport is established to simulate the distribution of sediment siltation downstream of the floodgate, and several conclusions are obtained in this paper which can provide some theoretical basis for the prediction and analysis of the siltation characteristics in lower reach caused by floodgates in estuaries.

Abstract:

Siltation, the accumulation of sediment particles in aquatic environments, poses significant challenges to water resource management, ecological health, and infrastructure maintenance. To effectively monitor and manage siltation, accurate data acquisition methods are crucial. Bathymetric data offer high-resolution spatial data, allowing for precise identification of sediment accumulation zones and the tracking of sediment transport pathways. This study focuses on siltation monitoring within an inland water channel: Abuloma River, using the bathymetric surveying data, which involves measuring the depth and morphology of water bodies. The bathymetric data was acquired using MK III single beam dual frequency echo sounders, processed and analyzed using Qinsy software. ArcGIS software was used to quantify sediment deposition rates, distribution, and changes in underwater topography. The result of the study shows a siltation rate of 762.249m3/year. This study underscores the importance of bathymetric surveying as a powerful tool in siltation monitoring efforts. It emphasizes the need for interdisciplinary collaboration between hydrologists, engineers, ecologists, and GIS specialists to effectively analyze and interpret the collected data. Ultimately, siltation monitoring using bathymetric surveying data contributes to a holistic approach in managing sediment-related challenges and promoting sustainable water resource management practices.

Abstract:

Siltation of dams appears as an urgent global concern, especially in arid and semi-arid regions concerned by the challenges of managing their limited water resources. These challenges worsen by the increase in water demand driven by population growth, aggravated by the adverse effects of climate change, in particular the siltation of dam reservoirs. This article focuses on the spatiotemporal analysis of the accumulation of sediments in Moroccan dam reservoirs. The methodology involves the collection, verification, correction, and interpolation of bathymetric data, which are organized and visualized in temporal and spatial dimensions using a dedicated Geographic Information System (GIS). The spatial distribution maps generated facilitate the identification of the area most severely impacted by the siltation of dams. The analysis emphasizes that siltation affects all Moroccan watersheds, with a particular emphasis on the Moulouya watershed due to the characteristics of its soil and its arid climate, further aggravated by heavy rainfall and deforestation. This integrated approach, combining bathymetric data with GIS technologies, improves our understanding of dam siltation in Morocco. The results provide valuable information for decision-makers and water resource managers, providing essential information for strategic planning and the implementation of measures to mitigate the impact of siltation.

Abstract:

The Three Gorges Project is the biggest hydraulic engineering and it brings great comprehensive benefits such as flood control, power generation, navigation, and water supply. According to the sedimentation prototype observation on the early stage of the Three Gorges Project operation, the sedimentation pattern of dam area and the upper part of power plant, as well as the channel sedimentation are analyzed after the systematic arrangement of the prototype observation, at the same time, the formation mechanism and development of siltation are studied based on river dynamics theory. The analysis shows that: the early siltation does not have important influence on the operation of the Three Gorges Project, the sedimentation of dam area occurs mainly in the wide section while little siltation in the narrow section and the siltation intensity is greater while the location is close to the dam from the view of the siltation distribution.

Abstract:

Ports at high siltation rates are covered with fluid mud layers which generally develop from short-term siltation. The presence of a fluid mud layer on the bottom of the channel has a considerable influence on ship behaviour, e.g. squat. The paper calculates siltation in an approach channel and its effect on ship motions. Firstly, siltation thickness and sediment density are predicted based on existing information of sediment, and the characteristics of mud layers are analyzed, Secondly, the squat and trim of ship navigating in the muddy areas are computerized. Finally a model through Monte Carlo simulation is presented to interpret the probability of ship grounding on the fluid mud layer.

Abstract:

Since the 92.2km-long , 350m-wide and -12.5m-deep draft channel was successfully achieved in the South Channel and the North Passage in the year 2010 , high siltation was found to temporally take place in the wet seasons , and spatially concentrate in the middle reach of the North Passage, where is consistent with the location of the traditional turbidity maximum zone (TMZ) of the Yangtze Estuary. The data from 2011 to 2015 show that the average annual siltation in the draft channel reached 80 Million m3 per year. With systematic analysis of the sediment source and comprehensive investigation on the mechanism of the flow and sediment transportation and siltation in the North Passage, this paper reveals a major cause of the back-siltation in the middle reach and subsequently discusses several engineering measures proposed to reduce the siltation . The final-selected engineering measure has been implemented quite recently , and the preliminary study shows that desired effect has been produced by the engineering measure.

Abstract:

Abstract: Mining activities on Homonhon Island, Philippines, have increasingly contributed to coastal water pollution and siltation, particularly during extreme weather events. This study investigates the influence of climatological factors—specifically precipitation—on mining-induced siltation using satellite-based remote sensing. Sentinel-2A imagery was employed to monitor and quantify changes in water turbidity and sediment deposition before and after typhoon events. Two spectral indices, the Normalized Difference Water Index (NDWI) and Normalized Difference Turbidity Index (NDTI), were applied to assess the extent of siltation across different time periods. Results revealed a notable increase in siltation areas following typhoons, with the year 2023 showing a surge of approximately 11 million square meters of affected areas, despite receiving only 23.9 mm of rainfall. This indicates that cumulative land degradation from mining operations may have heightened siltation susceptibility even under moderate precipitation. These findings highlight the critical role of satellite-based monitoring in supporting sustainable land use and coastal resource management in mining-affected regions.

In the initial operation stage of some ore wharf, the silting situation appears in the wharf apron; through the on-spot hydrological, geological and topographic survey and combination with a lot of previous data and the project implementation, the research is made into the hydrodynamic sediment conditions in the water area and the changes of topographic erosion and siltation. The analysis shows that the siltation is related to many factors, including: the natural siltation effect, the effect of erosion adjustment period, the effect of sand excavation and dredging, and the effect of wharf construction. Among which, the local excavation in the rear of the wharf under construction has a great effect on the siltation of the wharf apron.

Abstract:

The discharge of Arvand River and tidal currents affect the large siltation at Nahre Ghasr Fishery Port, located at the Nahre Ghasr channel, the Persian Gulf. Using 2DH and 3D numerical models, the flow pattern at the channel was investigated to study the details of siltation problem. The local model was calibrated by the measured data of water surface and suspended sediment rate. The main flow mechanisms that can affect the rate of siltation including the horizontal exchange, the vertical exchange and tidal filling, were analyzed. The study showed that tidal filling plays the dominant role on the sedimentation at Nahre Ghasr channel. Different scenarios were also examined for reducing the siltation rate at the port.

Abstract:

The effectiveness of small reservoirs in a mountain landscape continuously decreases over time due to the gradual siltation. We examined two hypotheses about the enhanced siltation rate and the constant relative contribution of unpaved roads to the siltation of a small water reservoir in the period 1990–2014, with pronounced climate change, compared to the reference period 1970–1989. Analysis was based on deposit volumes extracted from the reservoir in 1989 and detected at the reservoir bottom in 2014. The geographical information systems, image analysis and universal soil loss equation were applied to model the soil erosion according to the two sources—catchment area and roads—to study siltation processes in depth. Despite expectations, rates of siltation were almost unchanged in compared periods. The positive changes in vegetation cover (the forest expansion and changes in forest management practices) offset the enlarged rain erosivity. On the other hand, road erosion increased by 41% from 1990 and became twice as much a contributor to sediments compared to 1970–1989. The intensity of erosion from roads was from 13 to 29 times greater than from other areas. Therefore, proper maintenance of road networks could rapidly decrease reservoir siltation. Moreover, we recommend continuous cover forestry as a critical measure for central Europe’s forested regions to prevent growing erosion pressures.

Abstract:

In recent years, the resulting siltation from railway debris flow disasters has seriously affected the normal use of railway traffic lines and brought great challenges to rescue work. In view of this, we used an orthogonal test scheme to prepare different types of debris flow accumulation and carried out penetration resistance tests in order to explore the effects of different types of curing agents, the amount of curing agent added, the moisture content of debris flow siltation, and the grain gradation of debris flow sediment on the solidification strength of debris flow siltation. We also utilized scanning electron microscopy (SEM) to observe the microstructure and potential curing mechanism of the samples treated with different curing agents in attempt to discern the reasons for their different levels of strength. Our results show that the each of four curing agents tested can effectively improve the solidification strength of the siltation. Furthermore, we found that the type of curing agent had the largest impact on the curing strength of the siltation, followed by the moisture content of the siltation itself, the amount of curing agent added, and particle size. To achieve the best results, we recommend using 14% sulfoaluminate cement as the curing agent.

Full text

Abstract:

The performance of urban drainage systems can be significantly compromised by siltation in pipeline networks. This study focuses on the drainage network of central Zhengzhou, analyzing operational risks under current siltation conditions. Using complex network theory, the study examines the structural characteristics and propagation mechanisms of the siltation propagation chain, quantifying node risks through indicators such as pipeline risk factors and degree centrality. Edge vulnerability is incorporated to evaluate the risk values of siltation propagation paths. The study’s findings indicate the following: (1) Despite a relatively low overall siltation risk, regular pipeline inspection and maintenance is necessary. (2) A total of 22 critical nodes, primarily located in main pipelines or confluence manholes, exhibit high risk and require priority attention. (3) Siltation propagation shows significant chain characteristics, with main pipeline and junction node failures potentially leading to systemic crises. In the central Zhengzhou stormwater network presented in this paper, high-risk factors are concentrated in a southern downstream outlet caused by an edge identified as critical that propagates siltation risks to the downstream nodes, forming a long path with elevated risk levels. This study provides crucial insights into the risk management and prevention of sedimentation and blockages in urban drainage networks, not only offering important technical references and a solid scientific basis for pipeline maintenance and network upgrades—thereby contributing to drainage system planning and the enhancement of urban flood protection capabilities—but also serving as a valuable technical reference for improving the overall resilience and operational efficiency of drainage systems.

Abstract:

Soil erosion is a major factor leading to dams’ siltation and reducing their storage capacity. This study mapped the hot spots of soil erosion areas to predict the soil erosion/siltation in the Ghiss basin/dam (northeastern Morocco). In this context, various data has been prepared in the geographical information system for the estimation of soil erosion by integrating the universal soil loss equation (USLE). The result of this study revealed that soil loss rate ranges between0 and 19 t∙ha−1∙yr−1. Therefore, the hot spots in the soil erosion area are to be found upstream, potentially leading to dam siltation over time. To avoid Ghiss dam siltation, we suggest terrace farming and reforestation in the soil erosion area hot spots.

Abstract:

Sediment diverted from the Lower Yellow River is crucial for irrigation district sustainable development. As a complex problem, spatial distribution of sediment in district is related with natural geographical environment, incoming water amount and sediment concentration, methods of treatment, engineering facilities. Analysis of sediment distribution is the precondition for sediment utilization, transportation and treatment. As Bojili irrigation district for example, the paper analyzed sediment siltation characteristics in desilting branch, main canal, branch canal and field ditch with long term observed data from 1985 to 2009. Proportions of sediment siltation in different parts of irrigation system were calculated and difference of seasonal siltation in desilting branch was discussed. Besides, the paper proposed effective suggestions about reducing sediment siltation and improving transportation with long distance.

Forest fires are an increasing problem over recent decades. The fires, among other consequences, lead to an increase in the soil vulnerability to water erosion and a consequent increase in sedimentation rates. When barriers are present, such as dams or weirs, there is an amplified risk of sediment and ash deposition in their reservoirs, causing siltation. Thus, there is an interest in studying in more detail the risk of siltation of barriers and reservoirs in the Douro River watershed following wildfires. A detailed barrier inventory was lacking for the Douro River, hampering the identification of siltation-prone areas. In order to fill in this gap, an extensive inventory of barriers in the Douro river basin was carried out for the present study. The result was an abundant and reliable dataset on the Douro River barriers, which allowed a prognosis on the watershed siltation risk. The method for calculating the siltation risk relied on the relationship between the frequency of forest fires, the erosion risk and the frequency of reservoirs. The sub-basins with the greater siltation risk are the Tâmega, Corgo, Sousa and Paiva river basins. Most reservoirs with the highest siltation risk were from small dams. The modelling results were compared with stream connectivity and concentrations of stream water phosphorus (associated with the sediments that flow into the rivers due to the fires). With regard to connectivity, only two reservoirs were at high risk of sedimentation due to fires, so the categories of connectivity risk and fire-based sedimentation risk are probably not related. With regard to risk of high phosphorus loadings, in 8 basins the upper classes for fire-based erosion risk coincided with the upper class for phosphorus loadings suggesting that high phosphorus loading could be associated with fire-based erosion. This study works as a simple but reliable example on the assessment and mapping of siltation risk in stream networks intersected by abundant barriers. It allowed for identifying barriers that can accumulate a large quantity of fine sediments and ashes, interfering with water quality and soil erosion as well as with the storage capacity of the respective barriers.

Abstract:

Abstract Oujiang Estuary is a complex tidal estuary with many channels and shoals in the East China Sea, which was affected by typhoon frequently. The navigation channel of Wenzhou Port is located in the north branch of Oujiang Estuary, which happened serious sediment siltation in many times due to typhoon impact. The regulation is considered to decrease siltaion of the channel and protect shoals as well. According to the site survey data, the mathematic model is established and validated, which simulates the hydrodynamic, sediment transport and channel siltation due to typhoon in Oujiang Estuary. The channel regulation scenario is studied by the model simulation after analysis of the silation character. It indicates that the high concentration sediment from shoals north of channel is main sediment source caused siltation in the channel, which can be prevented into the channel by the regulation scenario and decrease siltation efficiently.

Abstract:

Sedimentation and siltation are jeopardizing water resources in Nigeria’s arid regions, threatening livelihoods and ecosystem. Sediment deposit is one of the principal and most serious technical challenge facing reservoirs today. Year-in, year-out, various dams are gradually losing their ability to store water for the purpose for which they were built, due to sedimentation and siltation. It is against this background that the National Water Resources Institute (NWRI), Kaduna, embarked on the study of reservoir sedimentation and siltation situated within the Arid and Semi-arid regions of Nigeria by the use of bathymetric surveys to ascertain their siltation levels. The study also looked at reported research findings from published works in the area of sedimentation and siltation to complement the findings from the field. The results indicated a substantial reduction in the storage capacities (i.e., original design depths) of all the reservoirs assessed by NWRI from 2012 to 2021 due to siltation and sediment transportation, and further supported by reported research findings from published works. This is not unconnected to their susceptibility to erosional features within and along the course of the main rivers and the tributaries feeding them, including climate change phenomenon. This decrease in storage capacity has also affected the diverse socio-economic activities which these reservoirs offer in these regions. This study intensifies the urgency of adopting sediment management strategies, including dredging, and erosion control, as this would improve water conservation, preserve reservoir functionality and sustain their diverse socio-economic benefits.

Abstract:

Siltation, the gradual accumulation of fine sediments, poses a significant threat to water quality, ecological balance, and sustainable resource management. This paper explores the various remedial measures and strategies aimed at mitigating the adverse impacts of siltation on reservoirs created by the construction of dams, particularly earthen dams. A range of remedial measures and management strategies are discussed. These include physical interventions, such as sediment removal techniques, sediment traps, and erosion control measures, as well as biological methods like the use of vegetation to stabilize riverbanks and improve sediment retention. Furthermore, we examine the role of sustainable land use practices, watershed management, and legislative policies in preventing and managing siltation. Through the implementation of these remedial measures, we can contribute to the preservation of our natural environment and improve the overall well-being of society.

Abstract:

Reservoirs in Taiwan have been experiencing severe siltation problems due to unfavorable environmental conditions and numerous harmful human factors. This research conducts a bench scale experimental study to explore the potential of using reservoir siltation (RS) in controlled low strength material (CLSM) particularly for subgrade applications. Test results show that RS can be used for producing of acceptable CLSM through proper mix design procedures. Considering the requirements of pavement subgrade constructions, this study recommends a water/solid ratio of 0.7~0.8 and a cement/water ratio of 0.4~0.5 can be used for the design. The study proposes a promising solution to reuse reservoir siltation, save natural resource of granular fill, and ensure the quality of pavement subgrade constructions in most cases.

Abstract:

In this study, an empirical curve describing the relation between erosion and deposition rate and water/sediment discharge was developed based on the recent evolution trend of the submerged delta at the Yangtze River Mouth, and the one-dimensional mathematical model for unsteady water-and sediment-transport was calibrated using the water and sediment discharge data after water impounding to predict the water and sediment discharge for the future 10 years and the future evolution of the submerged delta at the Yangtze River Mouth. The results showed that the 10 m and 20 m isobaths areas of the submerged delta changed with the water and sediment discharge from siltation to siltation slowing down to erosion. Siltation increased with large amount of rain received by the watershed during 1997-2000, while continuous retreat of erosion happened during 2000-2009. Using the one-dimensional mathematical model for river water and sediment calibrated and tested with data collected after impounding, the water and sediment discharges were calculated for Series 60 and 90, and its evolution in 2013-2022 was predicted for the delta. For Series 60, its 10 cm and 20 cm isobaths areas showed alternative scour and siltation, while the delta showed trends of erosion. For Series 90, its 10 m and 20 m isobaths showed substantial siltation in flood years. The water and sediment discharges since the Three Gorges Reservoirs was filled were lower than the calculated results for both Series 60 and 90. If the water and sediment discharges continue to decease, the delta will take an erosion trend.

Abstract:

Abstract The upper part of riverbed sediment is one of the key interfaces between surface water and groundwater, and biogeochemical process in this interface has a profound influence on the chemistry of infiltrated water. The lithology and permeability of bed sediment is mainly controlled by variation in river hydrodynamic conditions. However, there have been few studies of the effect of riverbed siltation on the hydrochemistry and redox reactions of infiltrated water due to the high variability in these processes and challenges associated with sampling. This study selected and examined a river channel near a site of riverbank filtration by drilling on the floating platform and conducting microelectrode testing and high-resolution sampling. The hydrodynamic and chemical characteristics of pore water in and lithologic characteristics of riverbed sediment, the siltation, and redox zone were examined and compared. Differences in hydrodynamic conditions changed the lithology of riverbed sediment, consequently affecting redox reactions during the process of river water infiltration. Variations in siltation changed the residence time of pore water and organic matter content, which ultimately resulted in differences in extension range and intensity of redox reactions. This study provides a valuable reference for understanding the effect of riverbed siltation on water quality of riverbank infiltration.

Abstract:

Abstract To alleviate the problem that the water level drops more and more seriously in recent years, Jiangxi province proposes to set up regulation gates at each of the estuaries of Ganjiang River to raise the water level in Nanchang city during the dry season. The operation of this project will raise the upstream water level, which means the sediment transport rate will decrease and lead to deposition problems. In order to find out the deposition area and development trend, we carried out the suspended sediment deposition test on an existing physical model. The study shows that the upstream sediment is mainly deposited in the reaches near the two deltas. Some special topographic features are more likely to cause siltation, such as the wide and deep thalweg and the backflow areas at the downstream of convex banks. After the operation of the project, the erosion trend of the upper reaches of the central and southern branches will change to siltation, and the siltation of the upper reaches of the Western branch will be further strengthened. Fifteen years later, with the decrease of the upstream sediment intensity, the sediment siltation phenomenon will gradually move downstream, however, this will be a long process.

Abstract:

In order to resist tides and salt intrusion, there have been more than 300 tidal gates built at many river estuaries in China since 1960s. However, the serious deposition occurred at a lot of gates due to the changes of hydrodynamic and sediment conditions and lack of discharge from the rivers. At present, the research is mainly to analyze the reasons for siltation downstream gates and the measures of dredging. It is not enough for study on distribution simulation of deposition downstream sluice. Studies have shown that 2D numerical model cannot reflect the distribution of sediment siltation downstream gates. Therefore, it needs to develop 3D sediment numerical model for deposition prediction. In this paper, combined the feasibility study of a tidal gate at Mulanxi River, a physical model and 3D numerical model of sediment siltation downstream gate are conducted.

Full text

Abstract:

With the continuous operation of check dams, the silting elevation of the whole dam gradually increases. When the silting height is close to the elevation of the broad-crested weir, it will result in a large change in the hydraulic characteristics of the original flow pattern. For subsequent reinforcement work, it is necessary to know how excessive sediment deposition affects the overflow from the broad-crested weir into the spillway. However, few studies about discharge coefficients are available in the case of spillways with sediment. In this paper, the hydraulic characteristics and discharge coefficient of a broad-crested weir whose width is 270 mm are investigated with physical experiments under different siltation heights and discharges. The research shows that: (1) With the increase in siltation height, the water level on the weir decreases and the drop of the flow becomes smaller. The overall flow pattern tends to the open-channel flow pattern. (2) In the same siltation height condition, the water surface profile along the broad-crested weir rises with the increase in discharge, and the surface velocity of the water in front of the weir increases with the increase in discharge. However, in the same discharge condition, the water surface profile along the broad-crested weir decreases with the increase in siltation height, and the surface velocity of the water in front of the weir gradually increases, which reflects that the increase in siltation height improves the overflow capacity of the broad-crested weir. (3) The present empirical formulas for the discharge coefficient have large errors when there is sediment accumulation. Therefore, a new formula for the discharge coefficient with sediment deposition is obtained using experimental data and its maximum relative error is 4.02%, which can provide a theoretical basis for risk elimination and reinforcement work on check dams in the Loess Plateau.

Abstract:

The article considers the results of the analysis and generalization of the materials of bathymetric surveys of the Krasnodar reservoir in 2005, 2016 and 2021. The Krasnodar reservoir occupies a key position in the Kuban reclamation complex, so its transformations caused by siltation cannot be underestimated. Special attention is paid to the geomorphological aspects of the transformation of the reservoir bed in the process of siltation, which directly affects the morphometric characteristics of the reservoir. According to a series of bathymetric surveys, digital elevation models of the basin and maps reflecting the distribution of bottom sediments and the processes of morpholithogenesis of the bed were constructed. During the period 2005–2021, the volume of sediment accumulation in the main reservoir, excluding the separated Tcshikskoe reservoir and deltaic sediments of the dividing bridge, amounted to 127 million m³. The greatest contribution to geomorphological transformations is made by fluvial processes, with the participation of which deltas of rivers flowing into the reservoir (Kuban, Belaya, Pshish, etc.) and estuarine avandeltas are formed. So, for 2016–2021. within the mouth of the Kuban seashore, the volume of sediments amounted to 9.36 million m³ or 38 % of the total volume of the siltation body in the reservoir, and the increment of the siltation layer over 5 years reached 2–3 m or more. Within the zone of variable backwater in the open part of the water area, bottom sediments are distributed relatively evenly with an increment of the sediment layer over 5 years of 0.01–0.4 m. The lowest rates of sediment layer increment were observed in the dead volume zone—less than 2 cm per year. During the study period, a decrease in the average annual volume of situation was recorded, which presumably indicates a gradual attenuation of the siltation process as the volume of the reservoir decreases.

Based on the observational data of water and sediment from 1998 to 2020, the seasonal and regional rules of water and sediment distribution in the Bojili Yellow River Irrigation District are analyzed. The characteristics of channel erosion and siltation are summarized from the changes of conditions along the channel and the sediment grain size on the channel bed. Considering the operation of the irrigation area, this paper deeply studies the siltation reduction technology, puts forward engineering measures such as the lining of the main, the first and the second canals, the extension of supporting projects, and slope adjustment of the east canal. Non-engineering measures are also proposed—planned diversion and irrigation, water saving and sediment reduction, regulation of water and sediment and so on. This report can provide technical support for the siltation reduction of Yellow River irrigation districts in the Binzhou City and even the Northern Shandong Plain.

Abstract:

Siltation around the harbour entrance poses significant challenges to the navigational safety and operational stability of coastal ports. Previous research has predominantly focused on sedimentation mechanisms in sandy coastal environments, while studies on silt-muddy coasts remain scarce. This paper investigates the causes of siltation around the entrance of Binhai Port in Jiangsu Province, China, utilising field observation data and a two-dimensional tidal current numerical model, with emphasis on hydrodynamic variations and sediment dynamics. Observations reveal that tidal currents induce sediment deposition in the outer harbour entrance area, whereas pronounced scouring occurs near breakwater heads. During extreme weather events, such as Typhoons Lekima (2019) and Muifa (2022), combined wind–wave interactions markedly intensified sediment transport and accumulation, particularly amplifying siltation at the entrance, with deposition thicknesses reaching 0.5 m and 1.0 m, respectively. The study elucidates erosion–deposition patterns under combined tidal, wave, and wind forces, identifying two critical mechanisms: (1) net sediment transport directionality driven by tidal asymmetry, and (2) a lagged dynamic sedimentary response during sediment migration. Notably, the entrance zone, functioning as a critical conduit for water– sediment exchange, exhibits the highest siltation levels, forming a key bottleneck for navigational capacity. The insights gleaned from this study are instrumental in understanding the morphodynamic processes triggered by artificial structures in silt-muddy coastal systems, thereby providing a valuable reference point for the sustainable planning and management of ports.

Abstract:

It has been determined that the reduction of siltation of the front chamber is necessary because the deposited sediments seriously violate the planned hydraulic structure of the flow when water is sucked up by pumps, as a result of which their efficiency decreases. The method of calculating the pipeline system of a new device designed to significantly reduce the siltation of the front chamber of irrigation pumping stations by artificially creating turbulence in the water flow in the bottom layer of the structure is presented. This calculation methodology is based on the use of the theory of flooded water jets, which makes it possible to determine the main characteristics of the jet. The latter allows calculating the design parameters of the pipeline system. The results of experimental studies are presented to compare the calculated data with the results of experiments, as well as to determine the effectiveness of the proposed device for a significant reduction in siltation of the front chamber of irrigation pumping stations.

Abstract:

During the reservoirs operation its gradual and continuous silting takes place. This entails a decrease in its regulating capacity and does not allow providing to water users the required volume of water in time. Many reservoirs in Uzbekistan were built 40-50 years ago, and the main large rivers have high turbidity, at present the reservoirs siltation is significant issue. The paper presents the study results of the Talimarzhan reservoir siltation, which receives water from the Amudarya River. An option for reducing siltation by using deposited sediments for soil fertilization is considered. During irrigation, suspended particles can be released onto irrigated lands. A chemical and biological analysis of the sediments deposited in the reservoir conducted, and considered their use as fertilizers. The suspended sediments were calculated as the product of the irrigation rate and water turbidity. The results showed that the sediments transport to fields contributes to an increase in crop yields, since silt fractions containing many useful organic matters.
