Summary: The distribution and flow of groundwater in karstified rocks can be extremely complex and not readily predictable, leading to costly failures in dam and reservoir construction due to inadequate investigation and interpretation of karst processes. Despite expensive and often ineffective remedial works, the construction of water storage reservoirs is crucial for socio-economic development in many karst regions, requiring the challenge to be accepted. Best practices for site selection of dams and reservoirs in various geological and hydrogeological settings are defined based on field experience in Europe and Asia, emphasizing the recognition of certainty or uncertainty in crucial parameters such as geological structure, groundwater regime, and depth of karstification.

Summary: This research aims to create, apply, and provide a novel indicator called Circularity Index for Dams/Reservoirs (CIDR) to evaluate the water circularity level in dual dam/reservoir systems. The method has been successfully implemented in 18 dam/reservoir systems managed by the Duero River Basin in Spain. The CIDR provides a single indicator value ranging from 0 to 55, with a higher value indicating better water circularity management.

Summary: Dams and reservoirs are widespread human-made infrastructures, but there is a lack of comprehensive spatial inventories for them. Existing datasets either focus on dam quantity and spatial coverage or detailed attributes for limited dams. To bridge this gap, researchers have introduced a new dataset, GeoDAR, which provides spatially explicit information for dams and reservoirs worldwide. This dataset is expected to have significant implications for hydrologic modeling, water resource management, ecosystem health, and energy planning.

Summary: The construction of cascade dams has resulted in the loss of longitudinal connectivity, fragmentation of habitats, slowed biota spread, and biodiversity loss in rivers. The study examined the functional diversity of zooplankton in a typical river with cascade dams and compared the differences between the upstream and downstream during dry and wet seasons. The findings showed that nutrient load and water quality degradation increased in the lower reaches of the river during the dry season, while the wet season did not show significant changes. The downstream zooplankton had significantly lower functional beta diversity caused by cascade dams during the dry season, and this difference was not prominent during the wet season. Environmental factors and dam numbers significantly influenced the functional diversity of zooplankton during the dry season, with the number of dams directly impacting the distribution pattern of zooplankton functional traits. The study highlights the impact of hydrological regulation by cascade dams on zooplankton functional diversity and suggests measures to mitigate these effects in different seasons.

Summary: The topography in the southwest karst region of China is complex, with limited surface water but abundant groundwater resources. Studying drought propagation and vegetation's water demand is crucial for protecting the ecological environment and managing water resources effectively. Various indices were used to characterize different types of droughts, and the correlation analysis and random forest method were employed to analyze the propagation time and importance of different water resources for vegetation. The study found that drought propagation was faster in the karst area compared to non-karst areas, and solar-induced chlorophyll fluorescence (SIF) showed greater sensitivity to drought and had potential for drought monitoring.

Summary: Based on a case study in Guangxi Province, China, this research analyzed the failure characteristics and mechanism of clay filler in karst caves. Geological survey indicated that the clay filler was formed by the deposition of surface clay entering the karst cave from the cracks of rock mass. The numerical simulation results showed that excavation induced sliding force and insufficient shearing strength of clay were the main triggers of instability of clay filler in the karst cave.

Summary: This study aims to investigate the vulnerability of groundwater to potentially toxic elements near the abandoned iron mine of Ouixane in Morocco. A modified DRASTIC method (DRSTI) was used and showed satisfactory results. The study found that high vulnerability zones accounted for 40% of the area, while medium and low vulnerability zones accounted for 42% and 18% respectively. The results were validated using groundwater geochemical analyses of potentially toxic elements, which confirmed that the geochemical quality of groundwater was mainly affected by the waste rock and tailings from the mine.

Summary: Water scarcity is a global issue, affecting approximately 1.2 billion people in areas with limited water resources. This problem is more severe in countries with arid climates, especially those heavily dependent on water for their economy. The Kingdom of Morocco is one such country, particularly in its southern regions. Therefore, creating a map of areas with high groundwater potential using available geospatial data can help optimize the selection of future wells in these areas.

Summary: This study investigates the role of volcanic detritus in the paleogeographic development of the Zagros Collision Belt. It reveals that the Sanandaj-Sirjan basin was filled with volcanic detritus derived from the Urumieh-Dokhtar Magmatic Arc during the Jurassic-Cretaceous. Some of these sediments uplifted as an accretionary prism during the Paleocene-Eocene, providing detritus to the foreland basin. These findings highlight the significance of volcanic detritus in the development of the Zagros Collision Belt.

Summary: In this study, advanced geostatistical techniques were used to investigate the spatial variability of rock mechanical properties at a reservoir scale. A 1-D model was built at each well using well log data, and a corresponding 3-D model was developed using geostatistical simulation techniques. 3-D seismic data were then used to optimize the geomechanical model. Results showed that the integration of well logs with seismic data increased the accuracy of field-wise 3-D elastic moduli models, and various co-simulation techniques demonstrated the improving effect of complementary data in constructing a more realistic reservoir geomechanical model.

Summary: In this study, we conducted a detailed evaluation of the Upper Miocene Qawasim Formation, an important hydrocarbon reservoir in the West Dikirnis field, onshore Nile Delta. By integrating various analysis techniques, such as petrographical thin sections, SEM, XRD, wireline logs, and routine core analysis, we identified eight lithofacies and four facies associations in the reservoir. The dominant lithology consists of massive subfeldspathic arenites with high intergranular porosity and good pore connectivity. We also observed diagenetic processes, such as feldspar leaching and cementation, which affect the reservoir quality. Based on our findings, we made inferences on drilling, completion, and reservoir management strategies.
