Groundwater is essential to modern human survival during drought periods. There is also growing geological evidence of springs associated with stone tools and hominin fossils in the East African Rift System (EARS) during a critical period for hominin evolution (from 1.8 Ma). However it is not known how vulnerable these springs may have been to climate variability and whether groundwater availab...

–Biological, chemical, and physical attributes of aquatic ecosystems are often strongly influenced by groundwater delivery. Nonetheless, access to predictions of groundwater contributions to rivers, lakes, and wetlands at a scale useful to resource managers is generally lacking due to the data requirements of current groundwater models. In this paper, we implement and validate a simple, terrain...

The Gravity Recovery and Climate Experiment (GRACE) delivers monthly gravity fields since it was launched in March 2002, which provides a new way to monitor the groundwater storage variations for large regions. In this study, we attempt to apply the GRACE data combined with estimated soil moisture based on the water balance approach to estimate monthly groundwater changes in the western Kansas ...

groundwater is the sole source of accessible resource for agriculture in zeviercherry- kherran plains and water quality often falls in brackish group. in order to determine the source of salinity and hydrochemical processess affecting groundwater environment of the area, 61 groundwater samples were taken for hydrochemical analysis and composite diagrams (two variant diagrams of total concentrat...

Overexploitation of groundwater resources has caused groundwater-related problems all over the world. Effective groundwater governance is a favorable guarantee for its protection and sustainable utilization. Accurate prediction of groundwater level (GWL) or depth to groundwater (GWD) plays an important role in groundwater resource management. Due to the limitations and complexity of numerical m...

Increasing pressure on water supply worldwide, especially in arid areas, has resulted in groundwater overexploitation and contamination, and subsequent deterioration of the groundwater quality and threats to public health. Environmental risk assessment of regional groundwater is an important tool for groundwater protection. This study presents a new approach for assessing the environmental risk...

The implementation of the EU Water Framework Directive demands participatory water resource management approaches. Decision making in groundwater quantity and quality management is complex because of the existence of many independent actors, heterogeneous stakeholder interests, multiple objectives, different potential policies, and uncertain outcomes. Conflicting stakeholder interests have ofte...
