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 ...

Integration of the rice paddy water management into a coupled surface-subsurface water flow model in the Sakuragawa River watershed (Japan)
Rice paddy water management was integrated into a distributed three-dimensional surface and subsurface coupling hydrological model of the Sakuragawa River watershed. This watershed is located in the Kanto Plain in Japan and includes the hillside of Mt. Tsukuba. Therefore, this watershed includes both steep mountainous areas and rice paddy-dominated flat land. Thus, water management of rice ...

Analysis of groundwater–surface water interaction in horizontal unconfined aquifer bounded by a stream and groundwater divide using a non–linear numerical model
In this study, a non–linear numerical model was developed to analyse the interaction between the drainage water moving from an unconfined aquifer and a surface water body. This interaction can occur during or after a rainfall event, which can cause the groundwater table to change. At first, a laboratory–scale aquifer model with stream and groundwater divide boundaries was established to examine ...

An investigation on the effect of geometric shape of streams on stream/ground water interactions and ground water flow
Ground water should be used efficiently and improved for sustainable water management plans. For this purpose, comprehensive ground water flow models are developed incorporating surface/ground water interactions. Typically, these models require a significant amount of hydrological parameters and the sensitivities of these parameters on interaction mechanisms need to be clarified. Therefore, in ...

Groundwater Level and Surface Water Depletion Linked
Study’s computer model could be influential in future water management A new study looking at a century of groundwater declines in the continental United States has concluded that overpumping water from aquifers is responsible for up to half of the river flow declines that now threaten economies and public health in many regions. The study, funded by the U.S. Department of Energy, said ...
