The objective of this research is to develop a fuzzy-based groundwater sustainability index (FGSI) model to evaluate the sustainability of groundwater system at selected cities in Asian.   The new Mamdani type fuzzy-based inference system known as FGSI was developed. It contains five components [...]

This study is the first to assess land subsidence in the Kathmandu Valley, Nepal. Land subsidence simulations were based on a fully calibrated groundwater (GW)flow model developed using a coupled surface–subsurface modelling system. Subsidence is predicted to occur as a result of deep aquifer [...]

This study aimed at evaluating three index-overlay methods of vulnerability assessment (i.e., DRASTIC, GOD, and SI) for estimating risk to pollution of shallow groundwater aquifer in the Kathmandu Valley, Nepal. The Groundwater Risk Assessment Model (GRAM) model was used to compute the risk of [...]

Groundwater is the essential resource for various uses and has great economic importance especially in the areas like Mekong Delta, which is the home for some 18 million people and produces a half of Vietnam’s rice and contributes a substantial part of the country’s [...]

For effective planning of activities aimed at recovering aquifer depletion and maintaining the health of groundwater ecosystem, estimates of spatial distribution in groundwater storage volume would be useful. The estimated volume, if analyzed together with other hydrogeologic characteristics, may help delineate potential areas for [...]

This paper develops a structured framework that considers an index of means for achieving sustainability, the ‘groundwater sustainability infrastructure index (GSII)’, as a measure of groundwater sustainability. The infrastructure here refers to the existing knowledge, practices, and institutions whose adequate strengthening helps achieve groundwater [...]
