Modelling of coastal hydrogeology of Krishna delta in India
Numerical techniques are widely used for modelling groundwater aquifers. Hydrological models are generally concept based and highly non-linear due to complex parameterisation as compared to models of other disciplines. Calibration and validation of such models cannot follow conventional methods borrowed from other disciplines many times due to scale of the model domain. In the present paper, ...

Groundwater flow and transport model of the Estonian Artesian Basin and its hydrological developments
The sophisticated research and management problems of the Estonian water environment are considered by means of holistic modelling. The model elaborated is based on the computer code Visual MODFLOW Classic. The model encompasses the entire Estonian Artesian Basin (EAB) and the border districts of Russia and Latvia. It involves all main aquifers and aquitards on an area of 88,000 km2. The main ...

Modelling the interaction of surface and subsurface water flow by linking TOPMODEL and MODFLOW
A coupled ground water–surface water model was used to quantify the hydrological processes in a lowland watershed. The model was constructed by coupling TOPMODEL and MODFLOW without writing new code for the integrated model. Meteorological, land use and soil type data for the Tenmile watershed, USA, were used to run TOPMODEL, which partitions precipitation into evapotranspiration, runoff and ...

The Influence of an Integrated Remedial System on Groundwater Hydrology
ABSTRACT This paper summarizes the development of a remedial system designed to hydraulically contain and ultimately reduce a plume consisting of primarily 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA). The system consists of groundwater circulating wells or extraction wells located in the core of the 1,1,2,2-TeCA plume to provide active source control, combined with monitored natural attenuation ...
