Abstract:

Abstract. Uncertainty in conceptual model structure and in environmental data is of essential interest when dealing with uncertainty in water resources management. To make quantification of uncertainty possible it is necessary to identify and characterise the uncertainty in geological and hydrogeological data. This paper discusses a range of available techniques to describe the uncertainty related to geological model structure and scale of support. Literature examples on uncertainty in hydrogeological variables such as saturated hydraulic conductivity, specific yield, specific storage, effective porosity and dispersivity are given. Field data usually have a spatial and temporal scale of support that is different from the one on which numerical models for water resources management operate. Uncertainty in hydrogeological data variables is characterised and assessed within the methodological framework of the HarmoniRiB classification.

Abstract:

The hydrogeological investigation is a work carried out by comprehensive utilization of various exploration methods to identify hydrogeological conditions in the target area, and develop and utilize groundwater resources. There are great differences in hydrogeological conditions in different regions. Hence, it is necessary to take exploration technology according to local conditions to master hydrogeological information as much as possible. Among them, the remote sensing (RS) technology can reflect the ground surveying and mapping results with high efficiency and precision through the analysis of satellite or aerial photographs, which is a commonly used method in the current hydrogeological investigation. According to satellite RS data, this work evaluates the distribution of groundwater levels in the study area and explores the geological and hydrogeological conditions of the groundwater system in the affected area. Firstly, the human-computer interactive interpretation method is used to analyze the topography and geomorphology conditions. Secondly, the spectral characteristic curve analysis method is used to extract the spectral characteristics of regional stratum lithology, and analyze and determine the lithology composition and structure of the aquifer. Thirdly, the single-band and multiband models of soil moisture RS estimation of groundwater level are implemented. Finally, the measured data are employed to verify and analyze the estimated value of the model. The results are in line with the actual value, and good results have been achieved.

Abstract:

Turbidite successions can behave either as aquitards or aquifers depending on their lithological and hydraulic features. In particular, post-depositional processes can increase rock permeability due to fracture development in the competent layers. Thus, at a local scale, turbidite systems warrant further detailed investigations, aimed at reconstructing reliable hydrogeological models. The objective of this work was to investigate from the hydrogeological perspective a turbiditic aquifer located in southern Italy, where several perennial and seasonal springs were detected. Considering the complex hydrodynamics of these systems at the catchment scale, to reach an optimal characterization, a multidisciplinary approach was adopted. The conceptual framework employed microbial communities as groundwater tracers, together with the physicochemical features and isotopic signature of springs and streams from water samples. Meanwhile, geophysical investigations coupled with the geological survey provided the contextualization of the hydrogeological data into the detailed geological reconstruction of the study area. This modus operandi allowed us to typify several differences among the samples, allowing identification of sources and paths of surface water and groundwater, along with diffuse groundwater outflow along streams. As a final result, a hydrogeological conceptual model was reconstructed, underlining how at a very local scale the lithologic, hydraulic, and geomorphological heterogeneity of the studied relief can lead to an improved hydrogeological conceptual model compared to that of other turbidite systems. These results open new questions about the hydrogeological behavior of turbiditic aquifers, which could be pivotal in future research. In fact, these systems could support relevant ecosystems and anthropic activities, especially where climate change will force the research of new (and probably less hydrogeologically efficient) water sources.

Abstract:

Abstract. When modelling contamination transport in the subsurface and aquifers, it is crucial to assess the heterogeneities of the porous medium, including the vertical distribution of the aquifer parameter. This issue is generally addressed thanks to geophysical investigations. As an alternative, a method is proposed using estimated hydraulic parameters from a 2D calibrated flow model (solely reliant on piezometric series) as parametrization constraints for a 3D hydrogeological model. The methodology is tested via a synthetic model, ensuring full knowledge and control of its structure. The synthetic aquifer is composed of five lithofacies, distributed according to a sedimentary pattern, and functions in an unconfined regime. The level of heterogeneity for hydraulic conductivity spans 3 orders of magnitude. It provides the piezometric chronicles used to inverse 2D flow parameter fields and the lithological logs used to interpolate the 3D lithological model. Finally, the parameters of each facies (hydraulic conductivity and porosity) are obtained through an optimization loop, which minimizes the difference between the 2D calibrated transmissivity and the transmissivity computed with the estimated 3D facies parameters. The method estimates values close to the known parameters, even with sparse piezometric and lithological data sampling. The maximal discrepancy is 45 % of the known value for the hydraulic conductivity and 6 % for the porosity (mean error 26 % and 3 %, respectively). Although the methodology does not prevent interpolation errors, it succeeds in reconstructing flow and transport dynamics close to the control data. Due to the inherent limitations of the 2D inversion approach, the method only applies to the saturated zone at this point.

Abstract:

The purpose of the study is generalization of data on the manifestations of hydrogeological earthquake precursors and volcanic activations based on long-term observations in the wells of the eastern part of the Kamchatka Peninsula. The main problem under consideration is the connection between the manifestations of hydrogeological precursors in several wells with the values of the magnitude Mw and epicentral distance of earthquakes to the wells de as well as with the parameters of seismic action in the observation area including specific density of seismic wave energy e and macroseismic intensity of shaking IMSK-64. The study results revealed that hydrogeological precursors in two-four wells had been manifesting for the period from 1 to 9 months before the strongest earthquakes with Mw = 6.6–7.8 at the epicentral distances de = 90–300 km. Such earthquakes were accompanied by the shakings of the intensity of IMSK-64 = 4–6 points. The specific density of seismic energy under such earthquakes was minimum 0.1 J/m3. The hydrogeological precursors were confined to the area for which the ratios of the earthquake epicentral distance de to the maximum linear size of the earthquake source L, km ranged from 1 to 3.7. Using the established relationships between the manifestations of hydrogeological precursors and earthquake parameters, weekly prognostic conclusions were made for expert earthquake prediction councils based on the data of current observations in wells. The well located at the distance of 15 and 20 km from the Koryaksky and Avacha active volcanoes featured the anomalous rise of groundwater pressure before the eruptions in 1991 and 2008– 2009. Therefore, a conclusion can be drawn that observation equipment operating in wells, the study results of hydrogeological precursors of earthquakes and volcanic eruptions as well as their application experience in the work of expert councils can form the scientific and technical basis for the development of geoinformation prediction technology for natural disasters in the Kamchatka Krai.

Abstract:

Underground development project activities for structures located below existing level of groundwater can cause changes in hydro-geological conditions on the construction site and adjacent territories and lead to development of unfavourable engineering-geological processes. Article presents results of hydrogeological forecast at the construction site with foundation pit enclosed in diaphragm wall. To recreate existing hydrogeological conditions and to create accurate model, inverse problem was solved with a multivariate selection of the filtration parameters of the modeled system in such way that there was a satisfactory alignment of modeled groundwater levels and groundwater levels marked during well-drilling, and analytical data, acquired during analysis and compilation of existing hydrogeological data. Upon solution of inverse problem to replicate existing hydrogeological conditions on the model, a series of forecasting tasks was undertaken to assess the impact of planned construction on hydrogeological situation of the construction site and adjacent territories. Construction was modelled in a multi-variant setting for a completely impermeable diaphragm wall and a permeable diaphragm wall with coefficient of filtration of 0.005 m/day. It is advisable to provide a comprehensive hydrogeological and geotechnical forecast at the design stage as it helps to predict how changes in hydrogeological regime affect deformation behaviour of surrounding buildings.

Abstract:

Abstract. Landslides, floods and secondary floods (hereinafter called phenomena) triggered by rainfall and causing extensive damage are reviewed in this paper. Damaging Hydrogeological Events (DHEs) are defined as the occurrence of one or more simultaneous aforementioned phenomena. A method for the characterisation of DHEs based upon historic data is proposed. The method is aimed at assessing DHE-related hazard in terms of recurrence, severity, damage, and extent of the affected area. Using GIS, the DHEs historical and climatic data collection, the geomorphological and hydrogeological characterisation of the hit areas, the characterisation of induced damage, the evaluation of triggering rainfall return period and critical duration of each DHE were carried out. The approach was applied to a test site in Southern Italy (Calabria) for validation purposes. A database was set up including data from 24 events which have occurred during an 80-year period. The spatial distribution of phenomena was analysed together with the return period of cumulative rainfall. The trend of the occurred phenomena was also compared with the climatic trend. Four main types of Damaging Hydrogeological Events were identified in the study area.

Abstract:

The article presents data on influence of non-operational landfills located in different hydrogeological systems on Lithuania groundwater quality. The landfills are located in open, semi-open, semi-closed and closed hydrogeological systems. The prevailing values of total dissolved solids (TDS) in the most intensive groundwater pollution zones of landfills can be divided into four TDS levels: low (400–3000 mg/l), moderate (TDS 3000–5000 mg/l), high (TDS 5000–20000 mg/l) and very high (TDS 20000–32000 mg/l). Groundwater with a low TDS level prevails in the most intensive groundwater pollution zones of landfills in open and semi-open hydrogeological systems. Groundwater with high and very high TDS levels characterizes about 3% of landfills in open and semi-open hydrogeological systems. The landfills in semi-closed and closed hydrogeological systems are also characterised by groundwater with a low TDS level. No landfills with a very high TDS level were found in semi-closed and closed hydrogeological systems.

Abstract:

The conducted researches have the purpose to develop the optimum approach which allows us to correctly estimate the hydrogeological conditions of buiding sites. The general patterns of formation, distribution and movement of groundwater within the sections of the planned and existing buildings and adjacent territories for Kyiv as an example were studied. For the study area and similar sites with complex hydrogeological conditions, which are caused by the alternation in section and in terms of layers of unsteady thickness with different filtration coefficients, it is more appropriate to use the method of mathematical modeling of geofiltration for predictive calculations. Since there is no detailed hydrogeological map of the site, it is advisable to build a natural hydrogeological model on the basis of engineering and geological survey data (groundwater levels data) for different periods reproducted by GIS. The obtained results make it possible to justify the mathematical model and to perform predictive modeling with sufficient accuracy for technogenically disturbed territories. The application of mathematical modeling allows avoiding unnecessary rough schematization of natural hydrogeological conditions, taking into account the complexity and diversity of boundary groundflow conditions, and thus give more realistic assessment of engineering measures impact on hydrogeological conditions of the territory. In order to take into account the patterns of formation, distribution and movement of groundwater for territories with dense urban development it is advisable, according to the authors, to simulate processes geofiltration according to the scheme given in this article. At the same time, the creation of scientifically sound mathematical and cartographic space-time natural hydrogeological model of the territory is the defining moment for further modeling. Application of Darcy Flow module of ArcGIS software enables to detect and specificate groundwater flow recharge and discharge conditions. This makes it possible, on the one hand, to avoid unnecessary schematization of natural hydrogeological conditions, and on the other hand, to take into account the complexity and diversity of groundflow boundary conditions, to give a more realistic assessment of possible engineering measures impact on the hydrogeological conditions of the territory during the construction.

Abstract:

Geophysical data combined with geological and hydrogeological data were analyzed to characterize the geometry of Oued El Hajel and Ouled Asker deep water tables (Sidi Bouzid). The obtained results allowed refining the geostructural schema by highlighting the individualization of the NE-SW underground convexity of Ouled Asker and the anticline of axis Es Souda-Hmaeima and Ezaouia on either sides of two hydrogeological thresholds. The geometrical analysis determined the spatial extension of Ouled Asker and Oued El Hajel subbasins. The seismic cartography of semideep and deep reservoirs (Oligo-Miocene; Eocene and upper Cretaceous) associated with the main subbasins contributed to proposing hydrogeological prospect zones for a rationalized groundwater exploitation.

Abstract:

The process of risk assessment and investigation of potentially contaminated soil and groundwater is highly dependent on a proper understanding of the geological and hydrogeological conditions of the investigated site. The current paper aims at identifying the general geological and hydrogeological conditions of the landfill areas around Bucharest city based on interpretations of the data available in research articles, books, public reports, and geological and hydrogeological maps. Several soil samples were collected, and laboratory analyses were conducted to validate the initial expectations in terms of physical properties of the underlying strata. Results were presented as cross-sections and piezometric maps suitable for developing tridimensional models, conceptual site models and contaminant fate and transport modeling with sufficient accuracy for environmental urban planning. The research provides a quick method which may be used when assessing the general geological and hydrogeological conditions of various sites in environmental studies. The vulnerability of the Romanian legislation in data management and decision-making was also highlighted, therefore a series of recommendations to improve the data availability and quality were provided.

Abstract:

Groundwater model has become a commonly used tool to perform various tasks. Geological, hydrogeological and geophysical data is required for constructing 3D hydrogeological framework models. Most of the time, it is realised that there is lack of sufficient data to build a groundwater model. The present work has been achieved after systematic data collection and hydrogeological study of Nara Basin, west Japan. Groundwater has been widely exploited for drinking water supply as well as for recreation purpose as Thermal Springs in the Nara Basin. There are hundreds of wells drilled in unconsolidated sediments and some tens of deep wells encountering the fractured basement. When water is exploited from a groundwater basin, it is necessary to understand properly the groundwater flow in different aquifer zones in the basin. Hydrostratigraphic units in the unconsolidated sediments overlying the basement rocks were established by using the borehole log data. In order to have understanding of the three dimensional configuration of these units, fence diagram was constructed. The geological and hydrogeological information were used to develop a conceptual model which was further calibrated and an acceptable model was obtained. The model was validated by comparing the observed and simulated heads and discharge.

Abstract:

Comprehensive information on fracture network properties around a borehole is indispensable for developing a hydrogeological site descriptive model. However, such information usually relies on various cross-hole field tests at a high cost. This study presents a cost-effective option regarding the identification of fracture network density around a borehole. Based on packer-test and drilling-core data from 104 boreholes in Taiwan mountainous areas, Barker’s generalized transient radial flow model and the concept of fractal flow dimension were used to reanalyze the existing hydraulic test data for obtaining the n value related to the geometry of groundwater flow for each test section. The analyzed n value was utilized to explain the characteristics of the fracture network in the adjacent area of each packer inspection section. The interpretation results were verified, using five hydrogeological indicators, namely rock-quality designation, fracture aperture, fracture density, hydraulic conductivity, and fracture/matrix permeability ratio. All hydrogeological indices have high correlations with flow dimension n values. Based on the verification results from using these indices, the proposed method in exploring such information was proven to be feasible. Finally, three practical relations were established, to provide additional information for designing and planning groundwater-related engineering systems in Taiwan mountainous areas.

Abstract:

Soil moisture (SM) plays a fundamental role in the terrestrial water cycle and in agriculture, with key applications such as the monitoring of crop growing and hydrogeological management. In this study, a calibration procedure was applied to estimate SM based on the integration of in situ and airborne thermal remote sensing data. To this aim, on April 2018, two airborne campaigns were carried out with the TASI-600 multispectral thermal sensor on the Petacciato (Molise, Italy) area. Simultaneously, soil samples were collected in different agricultural fields of the study area to determine their moisture content and the granulometric composition. A WorldView 2 high-resolution visible-near infrared (VNIR) multispectral satellite image was acquired to calculate the albedo of the study area to be used together with the TASI images for the estimation of the apparent thermal inertia (ATI). Results show a good correlation (R2 = 0.62) between the estimated ATI and the SM of the soil samples measured in the laboratory. The proposed methodology has allowed us to obtain a SM map for bare and scarcely vegetated soils in a wide agricultural area in Italy which concerns cyclical hydrogeological instability phenomena.

Adra town in southern Spain was the case study chosen to evaluate the groundwater resource contributed from the northern steep urban sector (NSUS) to the southern flat urban sector (SFUS), which belongs to the Adra River Delta Groundwater Body (ARDGB). The methodology included (1) geological and hydrogeological data compilation; (2) thirteen Multichannel Analysis of Surface Waves (MASW), and eight Ground Penetrating Radar (GPR) profiles to define shallow geological structures and some hydrogeological features; (3) hydrogeological surveys for aquifer hydraulic definition; (4) conceptualization of the hydrogeological functioning; and (5) the NSUS groundwater resource evaluation. All findings were integrated to prepare a 1:5000 scale hydrogeological map and cross-sections. Ten hydrogeological formations were defined, four of them (Paleozoic weathered bedrock, Pleistocene littoral facies, Holocene colluvial, and anthropogenic filling) in the NSUS contributing to the SFUS. The NSUS groundwater discharge and recharge are, respectively, around 0.28 Mm3 year−1 and 0.31 Mm3 year−1, and the actual groundwater storage is around 0.47 Mm3. The groundwater renewability is high enough to guarantee a durable small exploitation for specific current and future urban water uses which can alleviate the pressure on the ARDGB.

Abstract:

The article is devoted to the hydrogeochemical conditions of the Mesozoic hydrogeological basin within the Russkoye oil and gas field. The text gives valuable information on the natural conditions, geological structure, geotemperature regime of the bowels of the Earth and the composition of groundwater of the Aptian-Albian-Cenomanian, Neocomian, and Jurassic hydrogeological complexes. The change in the composition of groundwater in the section of the AptianAlbian-Cenomanian complex has been revealed. Vertical inversion zoning that traces the underlying the Neocomian complex is established. We describe the main features of the regional distribution of reservoir pressures. Hydrodynamic schemes of the Aptian-Albian-Cenomanian, Neocomian, and Jurassic hydrogeological complexes are given in the article. These schemes show that the Russkoye gas and oil field is located in the zone of low reservoir pressures. The above vertical inversion zoning and low reservoir pressures are associated with the location of the field within the elisional hydrodynamic water pressure system of the Yamal-Gydan lineaments. The data of the block-fault model of the considered field were used in the course of the study. The block-fault structure predetermined the migration of hydrocarbons and the formation of tectonically screened deposits.

Abstract:

Background. In hydrogeological terms, the territory of the Barents-Kara shelf has not been studied in sufficient detail. The data on its hydrogeological zoning are based mainly on the results of research undertaken in the 1970s, when attempts were made to isolate artesian shelf basins according to a set of hydrogeological indicators of oil and gas content. Currently, the position of the basin boundaries can be adjusted using current data from oil and gas and geological zoning and the hydrogeological testing of wells.Aim. To conduct the hydrogeological zoning of the territory of the southern part of the Kara Sea and the north of the West Siberian geosyneclise, including oil and gas structures — the South Kara syneclise and the Yamal-Gydan megasaddle, as well as to carry out a chemical analysis of groundwater of the Jurassic-Cretaceous aquifer complexes composing the sediments of the sedimentary cover of the West Siberian sedimentary basin.Materials and methods. A cartographic method was used to analyze earlier maps and schemes of hydrogeological and oil and gas geological zoning of the Russian sector of the continental slope of the Arctic Ocean, and then to determine the boundaries of the identified artesian basins. For a chemical analysis of groundwater, the results of hydrogeological testing of wells drilled at the Zapolyarnoye oil and gas condensate field were used.Results. The boundaries of two artesian basins — the South Kara submarine and the Yamal-Gydan semi-marine, corresponding to the same-name oil and gas prospective structures and having the same geological structure, were determined. Both basins are characterised by the presence of the main aquifer complexes of the Mesozoic hydrogeological floor of Western Siberia. When studying the composition of groundwater of the Zapolyarnoye deposit, it was found that the types of water change regularly with depth and an increase in the content of the hydrocarbonate ion due to the possible migration of fluids enriched with carbonic acid dioxide from the rocks of the foundation.Conclusion. The determined basins are characterised by a wide distribution of oil and gas-bearing structures and the exploration maturity of the sedimentary cover. Both artesian basins are characterized by the distribution of groundwater of a unified composition and genesis.

Abstract:

Since groundwater is the main water resource in Libya, groundwater information system (GWIS) is required as a decision support system (DSS) where it promises great potential for effective management and assessment of groundwater resources, and enhances the sustainability and efficient use of groundwater resources. This paper discusses the requirements and the design approach for the preparation of GWIS using geographic information system (GIS) techniques, where Al Waseetah area in Al Jabal Al Akhdar region was selected as a case study because of the availability of the hydrogeological data. The system structure and characteristics were defined and designed to store and manipulate the groundwater data, where 155 groundwater wells data were used to test and implement the GWIS system, in addition to remote sensing data as well as previous geological and hydrogeological studies. A series of maps and the hydrogeological map were produced and used to evaluate and interpret the groundwater system in Al Waseetah area.

Abstract:

The paper presents the results of a preliminary study of geology and hydrogeological conditions of a Grudziądz groundwater intake. The focus of the study was to develop a conceptual model that will be used in further investigation to create a hydrogeological model. In the intake area two multi-aquifer formations have been distinguished: Quaternary and Paleocene-Cretaceous. The Quartenary multi-aquifer formation, which consists of two aquifers separated by poorly permeable rocks, is primary utility. Groundwater in the Paleocene-Cretaceous aquifer has an elevated mineral content, which makes it not usable. The intake is located near Grudziądz and areas of intense farming, which leads to a hazard of anthropopressure, and may have a negative impact on the groundwater quality and quantity. In-office work conducted for the preparation of article included gathering and description of archival data from over 120 years of intake existence. Data from 53 hydrogeological boreholes have been analyzed. In 2017, field work was also conducted, including several measurements of water table in wells and piezometers of the intake. Water samples have also been collected for chemical analyses. An efficiency assessment of some observation wells has been made, establishing their hydrogeological parameters using the PARAMEX method.

Abstract:

The use of isotopic geochemistry for hydrogeological studies is growing internationally. The use of isotopic geochemistry methodologies on hydrogeological survey data, integrated with the use natural tracers, is helpful when defining the hydrogeological model of the aquifer. In particular, the use of radioisotope concentration measurements as natural tracers and the detection of the temperature, redox potential and dissolved oxygen in groundwater in the field provide information on underground water circulation, which is useful for identifying recharge areas and groundwater drainage. Variations in these parameters in the aquifer allow for information about its hydrodynamics to be obtained. The application of this method in a sample area showed how the uranium and radon concentrations, temperature, redox potential and dissolved oxygen vary in the different sectors of the aquifer, depending on water mobility. This information, integrated with the results of a hydrogeological survey of the static levels, distinguished the recharge and drainage areas of the aquifer and the preferential directions in terms of water flow and allowed for information on the mobility of the aquifer in the various sectors to be obtained. The method presented in this paper was tested in a larger hydrogeological study in the southern sector of the shallow aquifer of the S. Eufemia Lamezia plain (Calabria, Italy).

Abstract:

hydrological modeling is commonly crossed by the solution of inverse problems and the estimation for non-linear parameters techniques. Despite this common scenario, the use of these guidelines is limited to the proper sampling of in-field data. This sampling involves a variety of data that generally have little availability, especially in regions where geographical and climatic variability does not allow a constant measurement. In this article, we present the analysis of a regional underground flow model using two techniques: pilot points (PP) and constant zones (CZ). This methodologies allow identifying properly if there are any biased parameters and heterogeneity of hydraulic properties. For this purpose, we developed a numerical variable density model that is limited with reinterpreted data from real measurements. For the CZ technique, the initial parameters are assigned according to its layer, and every layer is considered constant for parameter values; in contrast for PP technique, the initial parameters are assigned according to interpolations using in-situ point measurements. The developed model was applied in an area under the influence of the ITCZ, located in the middle valley of Magdalena (MMV). This area is important on the development of the country due to its contribution to GDP and has been subject to significant changes in land use, as a result of intense economic activities, for example, agriculture, hydroelectric power, and production of oil and gas. The established model shows a scarce link with the observed state variable (hydraulic head -K), this proves the importance of spatial heterogeneity in K. The model is calibrated in order to establish K (as an anisotropic variable that varies spatially), the porosity (η) and the specific storage capacity (Ss) in the PP and CZ, reducing a “mean square” error of state variable dependable on the observation points. The results show that the PP system approach provides a better heterogeneity representation and shows that each parameter is sensitive, and does not depend on other parameters, giving to the parameter evaluation results factual independence and authenticity. This research compiles a methodology to assertively restrict a highly parameterized inverse model with field data to estimate aquifer parameters that vary spatially at a regional scale

Abstract:

The objective of the paper is to construct conceptual model of the oldest and most significant deposit of thermal mineral water in Bulgaria. The hot springs in the town of Kyustendil are located in the southern part, at the foot of Hisarlaka hill. The thermo-mineral water deposit is characterized by a high temperature of 73-76 °C, low TDS content of about 0.6 mg/l and a constant chemical composition. Summarized hydrogeological data of all previous studies for the region are presented. The representative hydraulic parameters of the geologic environment from hydraulic tests are described. The geological and tectonic environment in which the mineral waters occur is described in details. A categorization of faults with different directions is made in view of their hydrogeological significance for the Kyustendil water deposit. Thematic overview maps in GIS environment summarize the relevant information for the area. A hydrogeological conceptual model is composed with delineated boundaries for zones of recharge, transition, and drainage of mineral waters. A GIS model with a description of the geological, tectonic and hydrogeological environment of the Kyustendil deposit was built.
