Full textAbstract:
Abstract The timing of river entry in the Atlantic salmon is known to depend on genetic, demographic and environmental factors, but little is known about the relative magnitude of among population and among year variation and covariation in this respect in natural state Atlantic salmon rives. To investigate this, variability in the timing of river entry in three historical Finnish Atlantic salmon populations were analyzed using salmon trap data collected during 1870 - 1902. The analyses reveled that 1) the timing of river entry differed substantially and consistently among the rivers, and that 2) variation among the rivers was much larger than variation among years. Annual variations were not explained by regional environmental conditions, whereas in one river the timing of the local flood peak was a significant predictor of the timing of river entry. Differences in the timing of salmon entry to geographically closely situated rivers suggests that a regionally fixed opening date for coastal fisheries might not be the best management strategy as it may lead to uneven exploitation of salmon populations from different rivers

Olvios, Rethis and Inachos Rivers are multistory drainage systems that occur in Northern Peloponnesus, and at the present day they have and a reversed, North to South, flow element. Dervenios, Skoupeikos and Fonissa Rivers are the misfit streams of Olvios and revealed as juvenile streams and discharge to the Corinth gulf. Agiorgitikos River is the misfit stream of Rethis River and Seliandros River is the juvenile stream. Asopos, Nemeas and Rachiani Rives are the misfit streams of Inachos River and they also discharge to the Corinth gulf. Asopos River characterized as re-established stream. Physical factors such as tectonic regime (active and inactive faults), lithology, erosion and distance from the source influenced the three drainage systems evolution and could be influence them also in the future. The increase of human activities both in their southern parts and in the distal parts close to the coast could be change the physical evolution of the studied drainages, producing a new wind gap in the coastal area and a lake or a lagoon backwards of the coastal area, destroying villages and towns.

Full textAbstract:
In Malaysia, there are many rivers that are being the attraction for white water river activities. Perak, is a state on the west of Peninsular Malaysia has several rivers that are suitable for white water river activities and being among the favourite location for white water river activities enthusiasts. Among the well-known white water rivers in Perak state are Kampar River, Slim River, Sungkai River, Singgor River and Sungai Bernam River. The attraction of a white water river depends on several factors. One of the important factor is the classification of rapid difficulty level. To date, the classification of rapid difficulty level in Malaysia is based on the international standard scale and certified by The International Canoe Federation (ICF). Apart from that, other attraction factors such as river water quality, geographical location, logistics facilities, transportation access, facilities, operator reputations and promotions are among other attraction factors. This present study aims to identify the main attraction factors in the white water rivers in Perak State. Dynamic and structure profiling of the rivers was produced. The white water rivers selected in this study were Kampar River, Slim River and Sungkai River. From the study, Kampar River was identified to be the most preferred river for white water activities compared to Slim River and Sungkai River. Findings from the study was resourceful in the effort of constructing a complete profile of white water rivers structure located in the state of Perak besides promoting white water river activities as a structured recreational tourism activity in Perak.

Full textAbstract:
In recent years, the ecological environment of plain rivers within Haihe River basin is questionable because of severe water shortages. Most of the rivers dry up regularly and it is therefore necessary to take measures to improve the river ecological environment. Meanwhile, flood control is the principal function for most of the dried-up rivers, so river regulation works for flood control also should be undertaken. In this paper, some measures of river regulation were selected applied to the Haihe River basin, taking these measures not only ensure the river security but also realize its ecological benefit. Examples of the application of selected measures for the representative rivers, Yongding River and Hutuo River, both located within the Haihe River basin, are also assessed. These measures provide practical solutions to ecological and flood control problems of dried-up rivers, are generic in nature, and could therefore be applied to other same type rivers.

Full textAbstract:
Most of the world civilizations are developed in the river basins. However, we do not have too big rivers in Nepal, though Nepalese culture is closely related with water and rivers. All the sacraments from birth to the death event in Nepalese society are related with river. Rivers and ponds are the living places of Nepali gods and goddesses. Jalkanya and Jaladeviare known as the goddesses of rivers. In the same way, most of the sacred places are located at the river banks in Nepal. Varahakshetra, Bishnupaduka, Devaghat, Triveni, Muktinath and other big Tirthas lay at the riverside. Most of the people of Nepal despose their death bodies in river banks. Death sacrement is also done in the tirthas of such localities. In this way, rivers of Nepal bear the great cultural value. Most of the sacramental, religious and cultural activities are done in such centers. Religious fairs and festivals are also organized in such a places. Therefore, river is the main centre of Nepalese cultural activities and we can find the remains of ld cultural remains in river basins.

Abstract The aim of this research is to fill in the theoretical gaps regarding the typology of river parks, seen based on the shape and location of parks in relation to rivers, with a case study of parks on the island of Kalimantan. The typology of river parks will open new advanced research opportunities in the field of river park research. The method used is qualitative, with a field observation approach (primary) in twenty-seven parks on the river, field survey observations were carried out, and database (secondary) observations in fifteen parks on the river border were carried out through Google Street View “Big Data Base Analysis” (GSV). As a result, the typology of parks on rivers can be seen based on the shape and location of the park on the river, so that it is divided into three park typologies, namely the first typology of parks on rivers, the second typology of parks on riverbanks, and the third typology of parks bordering rivers. These three typologies are subdivided into eight form variants which are divided based on the potential point of view of the river, adaptation of the park design to the physical nature of the river, functional use of the banks and borders.

Full textAbstract:
Stream structure is usually dominated by various human activities over a short term. An analysis of variation in stream structure from 1979 to 2009 in the Qinhuai River Basin, China, was performed based on remote sensing images and topographic maps by using ArcGIS. A series of river parameters derived from river geomorphology are listed to describe the status of river structure in the past and present. Results showed that urbanization caused a huge increase in the impervious area. The number of rivers in the study area has decreased and length of rivers has shortened. Over the 30 years, there was a 41.03% decrease in river length. Complexity and stability of streams have also changed and consequently the storage capacities of river channels in intensively urbanized areas are much lower than in moderately urbanized areas, indicating a greater risk of floods. Therefore, more attention should be paid to the urban disturbance to rivers.

Full textAbstract:
The article presented the research results on the carrying capacity of some intra-provincial rivers in Bac Ninh province, using indirect assessment methods to assess the capacity of receiving wastewater and the carrying capacity of the river. The results of this study were the basis for Bac Ninh province to publish information on the environment of rivers and river sections that are no longer capable of carrying loads. The results showed that the whole Ngu Huyen Khe river was polluted, and no longer capable of receiving more pollutant loads of waste sources. For the Tao Khe river, section 1 of the river was still capable of receiving additional loads; from section 2 to section 6, the water quality indicators were completely unable to receive additional pollutant loads from waste sources. For Ngu river, section 1 and section 2, water quality was severely degraded, however, from section 3 to section 6, the water quality was somewhat improved. For Dau river, the whole river has reduced water quality and was no longer able to accept the pollutant load from the discharge sources. For Bui river, the water quality can be assessed as slightly polluted. For Dong Khoi river, the whole river had quite good water quality. Comparing pollution levels among rivers showed that the pollution level of Ngu Huyen Khe river, Dau river and Tao Khe river was the highest, and the ability to receive wastewater was almost no longer available. The rivers with less pollution were the Ngu and Bui rivers, the river with the best water quality is the Dong Khoi river.

Full textAbstract:
Temporary rivers and streams that naturally cease to flow can be found on every continent. Many others that were once perennial now also have temporary flow regimes due to the effects of water extraction or changes in land-use and climate, while others that used to run dry no longer do so due to water releases and waste water discharges. The dry beds of temporary rivers are an integral part of river landscapes and have: a role as seed and egg banks for aquatic biota; a unique diversity of aquatic, amphibious and terrestrial biota; a role as dispersal corridors; as temporal ecotones linking wet and dry phases; and as sites for the storage and processing of organic matter and nutrients. They also have a societal values, such as significance in human language and culture; agricultural uses; sources of sand and gravel for building purposes; and as places for recreation. ‘Traditional’ conceptual models of riverine ecosystem structure and function do not consider the dry phase. As a consequence, these models are incomplete and are thus not fully applicable to many parts of the world where temporary rivers are common and the dry phase is significant.Thesis (PhD Doctorate)

Full textAbstract:
This research attempts to fill in some specific gaps in the area of economic valuation of non-market goods and services with respect to development projects, and the integration of those values in the policy decision-making process. The concept and theory of non-market valuation and project appraisal are examined. In a developing country context, the conventional contingent valuation method is extended to include respondents' contribution in terms of time, irrespective of their decision to contribute money. This extension of the conventional contingent valuation method allows the inclusion of economic activities that are non-monetized and transactions in the form of 'barter exchange', which are typical for developing countries such as Bangladesh. The values generated by this new approach are integrated into an extended cost-benefit analysis, which reveals that the cleanup of dying rivers is not only an environmental imperative, but is also socially and economically justifiable. Apart from the theoretical investigation, another important dimension of this research is to contribute to the policy decision-making process with regard to public sector investment in developing countries.
The Buriganga River, which passes through Dhaka City, the capital of Bangladesh, has been selected as the case study for this research. Although considered to be the lifeline of the capital, the city part of the Buriganga River has become biologically and hydrologically dead because of the indiscriminate dumping of domestic and industrial wastes, encroachment by unscrupulous people, and negligence on the part of the authority to enforce rules and regulations pertaining to the ecological health of the river.
A cleanup programme has been designed for the Buriganga River to restore its water quality and develop new facilities in and around the river. This hypothetical cleanup programme is used: (i) to estimate the non-market benefits of an environmentally healthy waterway; (ii) to measure the total benefits; and (iii) to examine the desirability of public funding for the cleanup programme. An extended contingent valuation (ECV) survey of 400 households was carried out in Dhaka City in 2001. It reveals that not only are a significant proportion of the respondents willing to contribute direct cash for the environmental improvement of the river, they are also willing to contribute their time. When the contribution in terms of time is monetized, it is estimated to represent about 60 percent of the total contribution (the remaining 40 percent being cash payment).
The total non-market benefits from the Buriganga River cleanup programme are estimated at Tk 388 million (US$ 6.80 million) in the first year, rising to Tk 1805 million (US$ 31.66 million) by the 10th year of the programme. The public decision making process in Bangladesh does not consider such benefits. Failures to do so lead to gross under-estimation of the potential for, and contribution of, undertaking environmental improvement activities.
The total benefits of the cleanup programme are estimated within the framework of total economic value: the non-market benefits are estimated using the ECV survey inputs, and the market benefits are measured using secondary information, market methods and a benefit transfer approach. The cost estimate of the cleanup programme is made using market and secondary information with appropriate adjustments. The extended cost-benefit analysis (ECBA), which integrates the non-market benefits of the cleanup programme, shows that such public funding is worth undertaking. The study also reveals that a significant portion (68 percent) of this investable funding can be generated from the community.
The need for a cleanup programme of the Buriganga River is not an isolated case in Bangladesh. Many rivers in that country, and also throughout the developed and developing world are under threat of becoming biologically and hydrologically dead. This study provides a framework for addressing such environmental problems. It demonstrates that the ECV survey is a useful tool in estimating economic values of resources even in extremely poor economies. The modification of the contingent valuation method takes into account the local context, including cultural, economic, social and political settings. The extended cost-benefit analysis, which integrates better resource values could provide important information for the policy decision-making process. This is particularly useful for countries where the democratic system is not fully developed and there is limited experience in integrating the environment into the decision making.

Full textAbstract:
Over the past 200 years, rivers in industrialized countries have been significantly altered by human interventions such as channelization, hydropower development, and sediment mining causing observable biogeomorphological changes. In the European Alpine region, many large rivers have been impounded and channelized, yet few studies have conducted in-depth research on the temporal patterns of the causes and trajectories of these biogeomorphological responses, in comparison to rivers that can adjust their planform. Moreover, it is well-known that within channelized rivers alternating bars may appear due to an instability of the riverbed, but the development and influence of vegetation on such bars, its feedbacks on the morphodynamics of the bars and the degree to which these mutual interaction processes responds to anthropic stressors related to alterations in the flow and sediment supply regimes has received little attention.
The present research aims to disentangle the mechanisms that may determine dramatically diverging biogeomorphological trajectories in regulated Alpine rivers. It further intends to identify the underlying relations of the triad that connects vegetation – sediment – flow regime and its feedbacks in regulated, channelized, rivers with vegetated bars.
The methodology comprises an interdisciplinary approach which combines field and historical investigations with theoretical predictions, and integrates a variety of spatial and temporal scales and different levels of detail in characterising processes.
Two case studies in the Alpine region (the Isère river in southeast France and the Noce river in northeast Italy) were selected for a quantitative, historical analysis of the bio-morphological trajectories using remotely sensed data to investigate the apparent responses to human-induced modifications of natural processes. Both rivers have been heavily impacted, with a notable increase of human stressors since the mid-20th century which can be associated with the transition of both systems from an initial, stable dynamic state characterized by bars having only sparse colonizing vegetation with a frequent turnover to a new, apparently stable state characterised by reduced morphodynamics and an increased vegetation cover in recent decades.
The Isère river, which underwent a shift from unvegetated, migrating bars to vegetated, stable bars, was further explored with a hydromorphodynamic modelling approach to investigate historical changes in riparian vegetation recruitment and survival related to changes in the flow regime. The Windows of Opportunity model was successful at revealing temporal changes in recruitment conditions in response to flow regime alterations. Further results indicated a reduction in relevant high flow events that might be competent to induce large bar migration in the system. Alterations of the flow regime are assumed to have played a major role in vegetation encroachment directly by affecting vegetation recruitment through reduced flow disturbances and indirectly inducing modifications of bar morphodynamics.
Field observations of root development were also made on the Noce and Isère rivers, focusing on two species Salix alba and Phalaris arundinacea, with the aim of improving understanding of the role of roots on the presence and movement of vegetated bars. When comparing results from different sites, more predictable linear relationships between root properties and depth below the ground surface were associated with stronger flow regulation. Bar morphology (surface elevation or depth of sedimentation and sediment calibre) and flow regime were found to be the main drivers of root architecture. Furthermore, roots were found to have an important role in the stabilization of the bars with the ability to stabilise fine sediments trapped by the plant’s canopy during phases of bar aggradation.
To understand the current state of channelized Alpine rivers, which often show diverging biogeomorphic features, it is necessary to understand the underlying interactions between flow, sediment, and vegetation dynamics. Only through investigating the historical biomorphological evolution of rivers and the main drivers of that evolution it is possible to design measures that can be effective in rehabilitating desired ecosystem functions that have been markedly modified by those state transitions.
In summary, this study has provided novel, quantitative insights about the complexity of flow – vegetation – morphology interactions occurring in channelized river systems in relation to anthropogenic stressors causing alteration in their flow and sediment supply regimes. By integrating different approaches, this study has shown how these river systems can be highly sensitive to even small changes in the anthropogenic stressors, depending on the stage in their evolutionary trajectory, which is crucial to be detected to support the development of sustainable management strategies aimed at restoring or improving target riverine functions and processes.

Full textAbstract:
The wandering river pattern represents one of the last remaining river patterns that are not well understood. Many aspects of these rivers are not well known, particularly the processes of their creation and maintenance. The term wandering describes gravel or cobble bedded rivers, transitional between braided and meandering, with multiple channel sections around semi-permanent islands connected by single channel sections. This dissertation investigates the controls on the characteristics of wandering rivers within the Miramichi region of New Brunswick through time and at three nested spatial scales.At the scale of rivers, three factors appear to be needed for wandering to occur: (1) wide valleys, (2) channel energy between braiding and meandering, and (3) avulsion triggers, frequent overbank flows caused by icejams in the Miramichi. Principal component analysis showed that larger wandering rivers displayed greater anabranching intensity than smaller rivers, perhaps related to higher stage ice jams within larger rivers.
At the scale of channels, the wandering pattern of the Renous River was found to be in a state of dynamic equilibrium, with channel creation balanced by channel abandonment. The anabranch cycle model was developed to illustrate the temporal dynamics of anabranch creation, maintenance and abandonment within wandering rivers.
Also at the channel scale, principal component analysis of channel reaches within the Renous River displayed differences in grain size and hydraulic efficiency between side-channels and main-channels. Energy and sediment mobility within side-channels was related to their formation, maintenance and abandonment. Energy and sediment mobility within main-channels was related to mega bedforms called bedwaves. The apex of some bedwaves occurred at diffluences.
At the scale of channel elements, diffluences are stable where a large bar is formed and accretes upstream, creating a large reservoir of sediment upstream of anabranch channels to buffer their degradation. Where diffluences are unstable, a large bar forms within one anabranch channel to partially block flow and may cause its abandonment. The dissertation illustrates that within wandering rivers, processes occurring at multiple spatial and temporal scales interact to create and maintain the pattern.

Full textAbstract:
Aim of this research has been to make an analysis of long and medium term morphological dynamics that may affect the regulated gravel-bed braided rivers as the Piave river (Italy) and the Waitaki river (New Zealand).
The Piave river (drainage area around 4000km2), is one of the largest rivers in the north-east of Italy, the study reach is, mainly, 37 km long, and represent the intermediate course of the river within the mountain district. In addiction were been study different sub-reaches until a minimum of around 1,5 km long.
The Waitaki river (drainage area around 11000 km2), is a large gravel-bed river draining the eastern slope of Southern Alps, South Island, New Zealand, has been analyzed along a 13 km long subreach.
The flow regime and the sediment supply of these rivers have been considerably altered by hydroelectric dams, flow diversions and, along the Piave river, gravel mining. In addiction, river dynamics have been affected by the construction of stream-bank protection structures.
To document these changes, an historical analysis was performed using aerial photographs, cross section survey data and a LiDAR dataset.
Morphological features that were examine included planform configuration, active corridor extension, channel width, channel top depth, flow area, number of channels and bed elevation.
Vegetation features that were examine included, instead, areal island cover extension and different vegetation class extension.
The results indicate as remarkable changes occurred during the study period.
In both river there was a marked tendency to the diminution in the number of channels and in the active corridor extension, just subsequently to the main flood events is possible see an increase in the active corridor extensions.
Along the Piave river was possible see a marked tendency to narrowing and channel incision during the last 80 years.
The island, along both rivers, tend to encroachment and maturation for many years, occupying the active corridor. The island extension could decrease just after considerably flood events (RI > 10 years) or thanks to many close flood events. Regarding islands, has been possible see their tendency to joining with perifluvial vegetation, in consequence of long no-flood periods.Obbiettivo della presente ricerca è quello di eseguire un’analisi di lungo e medio periodo sulla dinamica della morfologia fluviale riguardante fiumi a canali intrecciati a fondo ghiaioso, sottoposti a regolazione dei regimi idrici, come il fiume Piave (Italia) e il fiume Waitaki (Nuova Zelanda). Il fiume Piave (area del bacino di circa 4000 km2), è uno dei principali fiumi del nord-est d’Italia; il tratto analizzato ha una lunghezza di circa 37 km e si trova nella parte centrale del bacino montano. Inoltre, sono stati studiati diversi sottotratti fino ad un minimo di 1.5 km di lunghezza. Il fiume Waitaki (area del bacino di circa 11000 km2) è il più importante fiume delle Nuova Zelanda per valori di portata, scorre dal versante est delle Alpi del Sud dell’isola del Sud della Nuova Zelanda; il tratto analizzato ha una lunghezza di circa 13 km. Il regime delle portate e l’apporto di sedimenti di questi due fiumi sono stati considerevolmente alterati dalla presenza di dighe per la produzione di energia idroelettrica e dalla presenza di opere trasversali e di difesa spondale. Per studiare le variazioni che si sono succedute nel tempo si è eseguita una ricostruzione storica con l’ausilio di fotografie aeree, dati storici di rilievi topografici e un set di dati LiDAR. Le caratteristiche che si sono analizzate sono l’estensione dell’alveo attivo, la larghezza massima dei canali, la profondità massima dei canali, l’area bagnata dei canali, il numero di canali e le caratteristiche altimetriche del letto del fiume. Si sono, anche, condotte analisi sulla variazione e la dinamica della vegetazione presente in alveo, attraverso la misurazione dell’area delle isole fluviali e l’estensione delle diverse tipologie di vegetazione presente nell’area perifluviale. I risultati ottenuti indicano come nel corso degli anni considerati vi siano stati delle variazioni considerevoli. In entrambi i fiumi c’è stata una marcata tendenza alla diminuzione dei numeri di canali e dell’estensione de corridoio attivo, solamente a seguito di eventi di piene rilevanti è stato possibile osservare un aumento dell’estensione del corridoio attivo. Lungo il corso del fiume Piave è stato possibile osservare una marcata tendenza all’incisione del canale durante gli ultimi 80 anni. Le isole fluviali tendono a maturare e stabilizzarsi per molti anni, occupando così il corridoio attivo. L’estensione delle isole diminuisce solamente a seguito di eventi di piena con tempi di ritorno marcati (> 10 anni), oppure a seguito di eventi che si succedono frequentemente, anche se di intensità minore. Infine si è potuto notare una tendenza delle isole fluviali a fondersi con la vegetazione perifluviale circostante, limitando ancor più l’estensione del corridoio attivo.

Full textAbstract:
AbstractThe PIANC InCom/EnviCom Working Group 236 was established in early 2021 to develop PIANC guidelines for improving navigability conditions on natural or quasi-natural rivers, while maintaining morphological processes and natural river form and function. Its key objectives include: 1) development of guidelines to improve and maintain the navigability in natural rivers; 2) assess the sustainability of river training works designed to improve the navigability; 3) assess the sustainability of dynamic river management (monitoring and shifting of navigation aids to adapt the navigation channel to the river dynamics); 4) highlight the technical, operational, economic and environmental considerations for navigation in natural rivers compared to that in regulated rivers and canals; and 5) improve the understanding of the physical processes in natural rivers, developed with or without river training works. The developed guidance includes a planning framework for developing a navigability improvement masterplan for a natural or quasi-natural river system, and the integrated and adaptive management strategies that can be applied at a system scale. Specific interventions and measures have been identified to meet the dual goals of maintaining morphological river function and improving navigability conditions. These measures include dynamic charting; morphological dredging and disposal management; Temporary, Adaptable, and Flexible Training Structures (TAFTS); riverbed armoring and sediment nourishment; rock excavation; meander cutoffs and oxbow development; localized traditional river training structures; and channel closure structures. The impacts and strategies for mitigation associated with some of the measures are analyzed and discussed. Finally, the continual monitoring, management, and operational tools available for improving navigability in a morphologically active river system is presented. It is recognized that natural and quasi-natural rivers will typically be more fluvially active and dynamic than systems that have used traditional methods for navigability improvements including heavily trained rivers or systems with locks and dams. These unrestricted and unconfined river systems, therefore, will require new and innovative strategies to monitor the fluvial and geomorphic changes of the system in order to inform managers and navigators of the river. Case studies are presented that include the Madeira River (Brazil); Magdalena River (Colombia); Niger Delta (Nigeria); Yangtze River (China); the Brahmaputra-Jamuna River (India); and the Red River (Vietnam).

Full textAbstract:
The previous development of densely populated urban-river areas neglected the river itself and its ecological values, which creates problems not only for the environment but also for the city and the social community. In order to ensure sustainable flood management and prevention in urban areas, multifunctional development of rivers has been promoted in recent decades, which emphasizes the role of rivers as a multifunctional network of open spaces, with the use of "blue-green" corridors and green infrastructure practices, and which views the river corridor as a resource with multiple ecological and social functions. In this paper, the basic elements of modern approaches to multifunctional development of the river and practical considerations for the rehabilitation of the Nišava river are given, and the advantages and importance of this approach for the city, the environment and the river are pointed out.

Full textAbstract:
River generation is an integral part of realistic terrain generation, since rivers shape terrains and changes in terrain, e.g., due to tectonic movements can change the path of rivers. Fast existing terrain generation methods often result in non-realistic river patterns, whereas physically-realistic techniques, e.g., building on erosion models, are usually slow. In this paper we investigate whether the Space Colonization Algorithm can be modified to generate realistic river patterns. We present several extensions of the Space Colonization Algorithm and show with a user study with $n=55$ participants that some variants of the algorithm are capable of generating river patterns that are indistinguishable from real river patterns. Although our technique can not generate all types of natural river patterns, our results suggest that it can prove useful for developing plausible 2D maps and potentially can form the basis for new terrain generation techniques.

Increasing environmental pollution and human intervention in nature today require the restoration, study, and monitoring of the positive effects on water quality in the restored rivers. Consequently, the main research questions arise: what are the main trends in river restoration impacting water quality and the watershed ecosystem? How does it contribute to the sustainable development of the environment? To answer these questions, this paper presents the results of the bibliometric analysis of papers from the Web of Science database and a keyword map of water quality in the restored rivers. The results of this study will help scientists and practitioners to monitor the restoration of the river ecosystem and its impact on water quality, and to choose further directions of river exploitation activity.

Full textAbstract:
River hydrology is a key component in river resources planning and river engineering. Our recent study is focused on flow metrics that best describe the registered flow regime and hydrological characteristics of rivers within the Tundzha watershed located in South Bulgaria. The flow regime will be described using 5 broad categories: magnitude of river flow; frequency; duration; timing and rate of change. A special attention in the research was given to the low flows. Thirteen hydrometrics stations were selected for the analysis. Data were obtained from the monitoring network of the National Institute of Meteorology and Hydrology, Bulgarian Academy of Sciences, Bulgaria. A flow duration analysis was done for each station in Tundzha River basin in order to estimate the probability of occurrence of different flows. Low flow frequency analysis was conducted. Baseflow indices were calculated to estimate the relative contribution of ground flow or baseflow. Regional regression equations were calculated between flow metrics and drainage basin area. Hydrological analyses play an important role not only in water resources projects but also in instream flow and fish habitat studies. Furthermore, we believed that such a regional characterization of river hydrology will help water resources managers to better deal with water issues.

Full textAbstract:
Abstract Crude oil leaking in rivers may cause serious damages, such as environmental pollution and death of river animals. The crude oil spreading in rivers could be much faster than that on lands, as the leaking crude oil may flow rapidly downstream with the flowing water. Therefore, accurately estimating the transient crude oil spreading area in rivers is a vital task for emergency response and disaster rescue. However, the estimating methods in the literature mainly refer to spreading process in underwater, ocean and soil, which commonly happened in the history. The crude oil transportation pipelines in China pass through many rivers with very complex channel geometries, introducing the necessity of estimating of leaking crude oil spreading in actual river channels. In the current study, the crude oil spreading process along an actual river channel is numerically simulated. The river channel geometry is extracted from a map database, which is further treated using image binarization and edge extraction to obtain the discrete river channel data. The river channel data is then smoothed by picking less data representing main geometric characteristics. The smoothed data is used to reconstruct the river geometry and generate calculation mesh. The mesh is a two-dimensional structured grid with several possible leaking points along the actual crude oil transportation pipeline passing through the river. A multi-fluid MIXTURE model is used to simulate the crude oil spreading process on the water surface, meaning crude oil blending in the flowing water. Cases with a leaking mass flow rate of 240 kg/s and a river flow velocity of 1.58 m/s are simulated for 10 possible leaking sources on the traversing pipeline. The effect of leaking locations and river channel bending on crude oil spreading on river surface were significant according to the simulation results. Sudden widening river channel may result in vortexes and slightly delays the crude oil spreading. The simulated data could be used to make the rescue strategy of crude oil leaking in this specific river.

Full textAbstract:
Rivers play a vital role in enhancing the identity of any city. Similarly, Mula, Mutha, and Mula-Mutha rivers are the identity of Pune city. When we look at the rivers of Pune closely, we will find the horrendous scenario. The major issues with the rivers of Pune are river flooding, river pollution, partial dry riverbeds, underutilized riverbanks, slum encroachment, and inaccessibility. These rivers are in a vulnerable state due to rapid urban growth. The unplanned growth of Pune city has degraded the quality of its river. The overall perspective towards the river has changed and the city is showing its back to its rivers. These kinds of scenarios have raised challenges for Pune city which is affecting the lives of its citizens. Therefore, we should investigate these issues closely and come up with the best possible compatible solutions for retaining the identity of the city and enhancing the quality of life. The riverfront development along these rivers can overcome these issues and integrates socio-cultural, economic, and environmental activities which are existing along the rivers of Pune.

Full textAbstract:
Detailed studies performed to design works at river crossings provide all the information needed to asses hydro technical hazards. TGN performed such studies for critical rivers as part of its Integrity Management Program. By monitoring performance of remediation works, experience was built throughout 10 years comprising different hydrological years. This was the base for the development of a simpler methodology aimed at assessing risk using information that can be readily available in regions such as Latin America where the existence of gaging stations and historic records at most rivers are not common. The method is based in river geomorphology, summarized with two parameters: area of drainage basin area and river slope at the crossing. They characterized the type of problems that can be expected and they can be estimated from topographic maps or digital terrain models available from the internet. The rating method follows a basic structure consisting in the product of two factors: causes and consequences. Causes include: bank erosion, river bed scour, meanders and river diversion along the right of way. Then, increasing factors are applied accounting for deforestation, land use and the occurrence of debris flows; decreasing factors consider proper remediation works, design and construction aspects implemented during construction. Finally, consequences are focused at loss of human life, impact on the environment, and interruption of fluid transport. This method is aimed to be performed by a pipeline operator that can have a good feeling of problems related to rivers, without having the technical knowledge of a specialized consultant. While rating, subjective judgment still plays an important role. However, this methodology provides a systematic approach that includes all aspects affecting river crossings, allows for prioritizing works based on rates and, as new rivers are included from new watersheds, it can be improved as prediction and characterization tool.

<p>Bangladesh lies on the river delta formed as the Padma River enters the Bay of Bengal. Much of the country sits just above the water level and the topography is characterised by a vast network of rivers, some of which are several kilometres wide. In recent decades, the country has seen the need for development of its transport infrastructure to support its economic growth. A major challenge has been the design and construction of river crossings, which encounter deep scour channels and poor ground in these rivers. COWI has developed designs for a number of major bridge crossings in the south and east of Bangladesh. Along with this, COWI has developed designs for platforms to support high voltage transmission line towers, which adopt the same engineering approach as applied to bridges.</p>

Full textAbstract:
The Automatic Identification System (AIS) shares vessel position information for navigational safety purposes. AIS broadcasts are received by other ships and terrestrial stations; however, in some areas there is no, or low, terrestrial station coverage to receive broadcasts. The US Army Corps of Engineers (USACE) developed an Online Travel Time Atlas (OTTA) to process AIS data and derive a transit count. This study examined OTTA output from 2020 and 2021 to identify areas of high or low AIS coverage along the Upper Mississippi, Illinois, and Ohio Rivers. Segments with a yearly average of two or more transit per day were classified as high coverage, those with less than a yearly average of two transits per day were classified as low coverage. Rivers were segmented using the USACE National Channel Framework reach boundaries. Results based on calculated vessel transits were as follows: Upper Mississippi River: 837.4 miles (98%) had high coverage, with 17.4 miles (2%) of low coverage; Illinois River: 190.5 miles (59%) had high AIS coverage, and 133 miles (41%) had low AIS coverage; Ohio River: 644 miles (66%) had high coverage, and 337 miles (34%) had low coverage. AIS coverage could be improved by raising antennae heights, installing repeater equipment, or adding towers.

As environmental uncertainty increases, incorporating resilience into project assessments, research recommendations, and future plans is becoming even more critical. This US Army Engineer Research and Development Center special report (SR) demonstrates how the concepts of resilience can be applied in a uniform framework and illustrates this framework through existing case studies on large inland river systems. This SR presents the concepts of resilience in inland river systems, the application of these concepts across disciplines, basic parameters of a resilience assessment, and the challenges and opportunities available for incorporating a more holistic approach to understanding resilience of the US Army Corps of Engineers mission areas on inland rivers. Finally, these concepts are demonstrated in several case studies in the United States to exemplify how these parameters have been applied to improve the overall performance of the system.

Full textAbstract:
The US Army Corps of Engineers, St. Louis District, Applied River Engineering Center (AREC), in cooperation with the Operations Branch of the Mobile District, conducted a sediment management study of the Sunflower Bend reach of the Tombigbee River, between River Miles 81.0 and 76.0, near Jackson, AL. The objective of the study was to look at sediment management alternatives to alleviate or eliminate repetitive maintenance dredging. These alternatives involved various river engineering measures including dikes, weirs, channel armoring, disposal armoring, and combinations thereof. A physical Hydraulic Sediment Response model was used to examine the sediment response resulting from these alternatives. During model testing, and after discussions with AREC and Mobile Operations Division staff, a second objective was established to define existing non-erodible bed materials that were located throughout the reach. This was conducted to examine the merits of strategically removing these erosion resistant materials in the river as an additional dredging/excavation alternative. The most favorable alternatives involved removing bedload sand and consolidated clay material from between River Miles 79.1 and 78.0 to improve navigation.
