Opis:
The research aimed to present an application of the technique based on the Dempster-Shafer theory for the determination of the shallow unconfined aquifer extent in a nonparametric (probabilistic) scale. The geology of research area is predominantly composed of the Pleistocene postglacial sediments. Only unconfined aquifers were taken into account in the study described in these paper. The resulting image showed a map of the aquifers’ extents in a probabilistic scale i.e. in a range between 0 (the lack of the aquifer, which is confirmed by research) and 1 (confirms the occurrence of the aquifer proved by research). Data analyses were carried out in the Geographic Information System. All the data were imported to the IDRISI. The Dempster-Shafer probability theory supported by the module BELIEF of IDRISI software was applied to the algebra of pixel maps.

Opis:
Pumping test are supposed to be one of the best ways of determining hydraulic parameters of examined aquifer. However, there are many other effects which control measured drawdown in a wellbore. One of the major effects is well clogging and well storage. Well clogging (also called skin effect (van Everdingen 1953)) causes additional drawdown in the well and well storage (Papadopulos & Cooper 1967) causes distortion of data in the first part of pumping test. The author shows that both these effects can be estimated from measured drawdown when two special approaches are used – first, the drawdown must be measured at very short intervals (0.5–1.0 second), and second, the pumping rates must be rather low, so the examined aquifer is not stressed enough (the drawdown in the aquifer is very small) and the skin effect/well storage influence is more significant in this case. This approach also eneables the interpreter to estimate more exact storativity coefficient, because evaluation of skin effect leads to better wellbore screen hydraulic losses estimation. Hydraulic losses caused by wellbore skin leads to the shift of Jacob’s line (Cooper & Jacob 1946) which is connected with storativity misinterpretation. A formula for eliminating this problem is also presented. Using this formula can help to estimate storativity coefficient by using measured data from pumped well. Drawdown measured in pumped well is rarely used for storativity interpretation precisely because of wellbore clogging. The formula partly eliminates that problem. In the end, application of presented approach is shown on several pumping test conducted in very permeable sand – gravel quaternary sediments of the Jizera River and the Elbe River. The pumping tests are first interpreted by casual methods – Theis (1935) and/or Moench (1997) – and then the new presented method is used. It is shown that closer to real values of storativity are gained when the newly derived formula is taken into account.

Opis:
The article identifies the hydrogeochemical environments controlling the chemical composition of groundwater in the Lódź agglomeration. The study was conducted with a different position of the groundwater table within: the Quaternary, Upper- and Lower Cretaceous aquifers. These aquifers are continuously exploited from a long time till present. The papers focuses on geogenic factors resulting from geological construction, lithology, circulation in the Lódź basin and anthropogenic factors associated with the change of the circulation system and the potential migration of pollution from the surface. The chemical composition of water from the Quaternary, Upper- and Lower Cretaceous aquifers was stable, without any anthropogenic changes. The hydrochemical inversion of water within the Cretaceous aquifers is the result of the different lithology of these aquifers and the variation in the way and magnitude of groundwater recharge.

Obszar badań o powierzchni około 50 km2 leży w północnej części Hanoi i obejmuje część Rzeki Czerwonej ze strefą przemysłową Thang Long na południu i fragment rzeki Ca Lo ze strefą przemysłową Quang Minh na północy. Na obszarze badań panuje klimat monsunowy z gorącym, wilgotnym latem i chłodną, suchą zimą. Względna roczna wilgotność wynosi 84% przy maksymalnych opadach 1532 mm i minimalnych 948 mm. Obszar leży na wysokości 5-10 m n.p.m. Występują tu dwie formacje wodonośne - górna, holoceńska (Qh), wychodząca na powierzchnię. Zwierciadło wody gruntowej znajduje się na głębokości 5-5.5 m pod powierzchnią. Dolna, plejstoceńska formacja (Qp), ma strop na głębokości 20-30 m. W obu woda jest słodka. Formacja Qp jest intensywnie eksploatowana jako główne źródło wody pitnej na tym obszarze. Zbiornik ten nie jest bezpośrednio narażony na skażenia, ale substancje zanieczyszczające mogą się przedostawać z formacji holoceńskiej (Qh) przez okna hydrauliczne.

Opis:
The rainfall irregularity in the Al-Hoceima area places the Ghis-Nekor coastal aquifer as a primary resource for water supply. However, it is of paramount priority to adopt management and optimization plans that can mitigate the effects of the irrational use of the resource and the deterioration of its quality in the region of our study. In order to study the alteration aspects of this aquifer, 26 wells were sampled and their suitability for irrigation was assessed. The sodium adsorption rate (SAR) values indicate that most groundwater samples fall into the risk classes of high salinity and low sodium (C3-S1) and high salinity and medium sodium (C3-S2). The results also show a medium to high alkalinity risk due to the high concentration of HCO3-. The excess of salts is largely due to the intensive exploitation of groundwater and to the phenomenon of salt-water intrusion into the coastal karst aquifer. As a result, the quality of groundwater is not adapted to sustainable agricultural production and soil balance, which requires controlled monitoring to ensure its rational use with a view to the sustainable development of the region.

Groundwater is the main source for many uses around the city of Ouargla. In this study, the DRASTIC method was used to assess the vulnerability of the groundwater aquifer. Seven hydrogeological parameters of the model (D water depth, R efficient charging, A aquifer type, S soil type, T topography, I unsaturated zone and C hydraulic conductivity) were measured and mapped. The intrinsic vulnerability map of the shallow aquifer, using the DRASTIC method, shows a high to very high vulnerability to pollution; 91.6% of the study area has high vulnerability, 8.4% of it has very high vulnerability. The comparison of the DRASTIC maps with the land use map illustrates that the agglomerations and irrigated areas are the most vulnerable areas to pollution, due to the low depth of the aquifer and the infiltration of significant domestic and irrigation wastewater. The results show that the relationship coefficient between the DRASTIC index and nitrate concentration is R = 0.73. This indicates that the groundwater vulnerability mapping by using the DRASTIC method can be applied for sensible groundwater resources management and land-use planning in the study area.

Opis:
Regional analysis of the Mesozoic and Paleozoic geothermal aquifers in the Polish Lowlands indicates that hot waters accumulated in Lower Cretaceous and Lower Jurassic deposits should be given priority in practical utilization. Crucial for this purpose are: high level of the geological recognition of the aquifers, occurrence of thick reservoir rocks, high water discharge, relatively high temperatures, particularly in the Lower Jurassic aquifer, and relatively low costs of drilling the production and injection wells. The Lower Jurassic and Lower Cretaceous water-bearing layers are represented by sandstone complexes with very good reservoir properties. This is favourable for high water discharge, which has beneficial influence on economical justification of construction of geothermal plants. The above findings have been confirmed by the so-far geothermal investments, among others the geothermal plants in Pyrzyce and Stargard Szczeciński, which utilize geothermal waters from the Lower Jurassic aquifer. Other plants, located in Uniejów and Mszczonów, central Poland, utilize waters from the Lower Cretaceous aquifer.

Groundwater residence time in the rocky environment of sandur areas was estimated with two methods i.e.: numerical modelling along the two lines of cross-sections and an isotope method (18O, 2H, 3H) for 6 samples. Chemical parameters (TDS, Cl) confirm the general trends of enriching water mineralization along the flow path in the sandur aquifer, as well as during infiltration towards the deeper aquifers.

Opis:
Groundwater exploitation that exceeds its recharge capacity can have a negative impact on the hydrogeological environment. Optimal exploitation means maximising pumping discharge with the least reduction in the hydraulic head. In groundwater exploitation, the position of wells, number of wells, and the discharge of groundwater pumping greatly determine changes in hydraulic head and groundwater flow patterns in a given hydrological area. This article proposes an optimisation model which is expected to be useful for finding the optimal pumping discharge value from production wells in a hydrological area. This model is a combination of solving the Laplace equation for two-dimensional groundwater flow in unconfined aquifers and the optimum variable search method based on the Shuffled Complex Evolution (SCE-UA) algorithm. Laplace equation uses the finite difference method for the central difference rule of the Crank Nicolson scheme. The system of equations has been solved using the M-FILE code from MATLAB. This article is a preliminary study which aims to examine the stability level of the optimisation equation system. Testing using a hypothetical data set shows that the model can work effectively, accurately, and consistently in solving the case of maximising pumping discharge from production wells in a hydrological area with a certain hydraulic head limitation. Consequently, the system of equations can also be applied to the case of confined aquifers.

Opis:
Iran, being located in arid and semi-arid regions, faces an increase in human demand for water, and the global climate change has led to the excessive use of groundwater. China, India and Iran were ranked from first to third, respectively, in excessive groundwater consumption in 2005. The effects of effective parameters on groundwater recharge such as precipitation, surface recharge and well water harvesting in the Karvan aquifer are assessed. Groundwater flow models have typically been and are being adopted since the beginning of this millennium to better manage groundwater resources. The decrease in groundwater level and the potential environmental hazards thereof have made the researchers here to apply the Groundwater Modelling System (GMS software) in 3D in the subject area. This modelling is calibrated and validated for 86 months at steady and unsteady states. In this study, six scenarios are defined as both an increase and a decrease of 30% in precipitation, both an increase and a decrease of 30% in surface recharge, an increase of 10% in well water harvesting and a decrease of 30% in well water harvesting. The best scenario is selected for the subject area water management.

Opis:
Faced with the challenges of sustainable groundwater resource management in the arid zone, the identification of reserves and their monitoring have become vital. This paper aims to identify the Turonian aquifer in the Cretaceous Béchar basin, and calculate its transmissivity, permeability and storage coefficient, as well as its evolution over time. This Turonian aquifer is characterized by marine limestones (gentle dip shelters 45° to the North and 5° to 10° to the South). Pumping tests revealed a transmissivity T of 10–4 to 10–2 m2·s–1, a permeability K of 10–6 to 10–4 m·s–1 and a storage coefficient S of approximately 10–3. Two piezometric campaigns, carried out between (1976–2018), show a converging and constant flow direction from the North–East to the South–West and from the North–West to the South–East towards the outlet of the basin. Decreased values were observed in the North and South–West borders due to isopiezometric lines. However, this water table is not in a stationary state, it shows seasonal and interannual fluctuations in relation to the variable rainfall and the exploitation rate. In terms of facies, the projection of the two hydrochemical campaigns, during 1976 and 2018 on the Piper diagram, did not show any significant evolution, they are concentrated in the chlorinated and sulphated calcium and magnesium facies.

Opis:
The chemical composition of groundwater is affected by many features, including the impact caused by surrounding rocks. The Nile aquifer is surrounded by the calcareous structural plateau along the Assiut governorate on both sides. This paper aims at studying the effect of surrounding rocks on the chemical composition of groundwater in the Nile aquifer along the Assiut governorate. Fifty-five samples were taken from drinking water stations and irrigation wells in 2015, and then analyzed chemically in water and soil fertility laboratory located in the irrigation ministry in Assiut. Aquachem software package was used to determine the groundwater type and rock source deduction. Piper-trilinear diagram was plotted to show the hydrochemical facies. Furthermore, Gibbs diagram was applied to determine the correlation between water composition and aquifer lithological characteristics. The results revealed that nearly all of the groundwater samples drop in the water-rock interaction field. The results of rock source deduction show that the ratio of Cl to the sum of anions is less than 0.8 for all samples, concluding that the rock weathering is dominant. According to the criterion of TDS values, 78% of all the samples indicated that the carbonate weathering is prevalent; in turn, the ratio of Mg to Ca plus Mg shows that limestone-dolomite weathering is predominant. These results confirm that the calcareous structural plateau surrounding the Nile aquifer along the Assiut governorate has an effect on the groundwater chemistry by interacting between groundwater and limestone rocks which are the main component of the calcareous plateau.

W artykule przedstawiono informacje geologiczne i hydrogeologiczne o płytkich poziomach wodonośnych w zachodniej części województwa mazowieckiego, w obrębie miasta i gminy Sochaczew, w aspekcie lokalizacji projektowanego otworu geotermalnego Sochaczew IG-1 oraz (wstępnie) o ich potencjalnej przydatności dla magazynowania energii cieplnej, tj. w jednym z przyszłych wariantów systemu ATES. Analizowane informacje pochodziły z bazy danych o obiektach, które zgromadziła Państwowa Służba Hydrogeologiczna (PSH). Uwzględniając dane PSH, zależnie od parametrów pracy projektowanego otworu geotermalnego oraz od charakterystyki przyszłych odbiorców energii z systemu ATES, a także w nawiązaniu do doświadczeń europejskich, stwierdzono możliwość budowy któregoś z wariantów systemu ATES (np. wykorzystującego do magazynowania energii jedną lub dwie warstwy wodonośne). Wstępnie wskazano rejon, w którym można by skorzystać z takich dwóch warstw po przeprowadzeniu dokładniejszych badań, np. geofizycznych oraz po testach i obserwacjach w przynajmniej jednej badawczej studni sondażowej.
The article presents geological and hydrogeological data about shallow aquifers in the western part of the Mazovian province within the town and commune of Sochaczew, in terms of the location of the planned Sochaczew IG-1 geothermal borehole and in terms of its potential for aquifer thermal energy storage (ATES). The analyzed data was from the drilled wells database of the Polish Hydrogeological Survey (PSH). Taking the PSH data into account, parameters of the planned geothermal boreholes, the characteristics of future energy consumers of the ATES as well as to European experiences, it has been found that it is possible to apply one of the variants of the ATES system (e.g. using one or two aquifers for storage). Initially the area was selected where two aquifers could be applied for the ATES system after detailed geophysical studies, tests and observations in at least one exploratory well.

W artykule omówiono wyniki prac laboratoryjnych, których celem było określenie wpływu wybranych parametrów procesu tłoczenia ditlenku węgla do modelu porowatej warstwy wodonośnej na skalę i dynamikę jego wypływu z tejże warstwy. Określono objętość warstwy, przez którą wypływał ditlenek węgla oraz stopień nasycenia (saturacji) warstwy wodonośnej gazem. Punktowe zatłaczanie ditlenku węgla do warstwy wodonośnej jest jednym z pierwszych etapów wykonywania poziomych barier izolacyjnych, zgodnie z założeniami Technologii Horyzontalnych Barier Krzemianowych (THBK). Celem technologii THBK jest likwidacja pionowego przepływu płynów w ośrodku geologicznym, co daje szerokie pole zastosowań w ochronie wód podziemnych i górnictwie. W pracy wykonano symulację procesu oraz zoptymalizowano parametry zatłaczania cieczy zabiegowej. Podjęto także próbę przeniesienia uzyskanych w laboratorium wyników do warunków płytkich warstw wodonośnych
