Global Groundwater Modeling and Monitoring: Opportunities and Challenges

Water Resources Research, 2021
Groundwater is by far the largest unfrozen freshwater resource on the planet. It plays a critical role as the bottom of the hydrologic cycle, redistributing water in the subsurface and supporting plants and surface water bodies.

Groundwater quality [PDF]

Water Environment Research, 2020
AbstractGroundwater is a vital component of water supply for residential, industrial, and agricultural purposes. However, many groundwater basins are being used unsustainably and groundwater contamination is a growing water quality problem. Although anthropogenic activities and natural processes have been increasing the contamination in this valuable ...

Detecting sources of water leakage in fractured limestone: Case study in Mokattam District, Egypt

Water Science
The paper investigates the sources of water leakage in Mokattam, Cairo, Egypt. It is considered a high-risk zone for landslides due to the presence of problematic soil, topography, and water conditions. The objective is to mitigate the negative impact of

Groundwater depletion will reduce cropping intensity in India

Science Advances, 2021
Groundwater depletion will reduce cropping intensity in India, and canal irrigation cannot fully substitute for this loss. Groundwater depletion is becoming a global threat to food security, yet the ultimate impacts of depletion on agricultural ...

A Coupled Hydro‐Mechanical Modeling Framework to Concurrently Simulate Coal Seam Gas Induced Subsidence and Groundwater Impacts

Water Resources Research
Land subsidence has been extensively studied and modeled in the context of conventional petroleum or water extraction. New challenges arise to model subsidence caused by coal seam gas (CSG) depressurization. CSG‐induced subsidence is a result of multiple

Numerical Modeling of Reactive Transport and Self-Sealing Processes in the Fault-Controlled Geothermal System of the Guide Basin, China

Geofluids, 2019
Strong chemical reactions in the geothermal systems may cause sealing of fractures, which reduces the permeability in the reservoir and subsequently affects the heat production.
