In this article, we present the use of coupled land surface model and groundwater flow SWAT-MODFLOW with decision support tool WEAP (Water Evaluation Planning software) to predict future surface-water abstraction scenarios in a complex river basin under conditions climate change. The modelling framework is applied Dee River catchment Wales, United Kingdom. Regarding hydrology, improves overall ...

The rich biodiversity in the floodplain area is influenced by both floods and groundwater (GW). To protect ecological environment area, it essential to study interaction between GW. objective of this paper propose a coupling strategy hydrodynamic model GW provide an accurate simulation tool for quantifying case conducted middle reaches Irtysh River northwest China. Firstly, two-dimensional base...

Purpose Groundwater plays a critical part in both natural and human existence. When surface water is scarce arid climates, groundwater becomes an immensely valuable resource. Dak Lak area that frequently lacks resources for everyday living production, the scarcity of exacerbated during dry season. As result, it to do study understand about meet region's demand. This aims extend use MODFLOW mode...

A detailed finite-difference approach is presented for the simulation of transient radial flow in multi-layer systems. The proposed discretization scheme simulates drawdown within the well more accurately than commonly applied schemes. The solution is compared to existing (semi) analytical models for the simulation of slug tests and pumping tests with constant discharge in singleand multi-layer...

Response time, describing how quickly a disturbed system would reach a new equilibrium, has been helpful to hydrogeologists in characterizing and understanding the hydrogeological systems. This study examined the complex response times associated with lake–groundwater perturbed by climate. Simulated hydraulic heads and lake stage values derived from a 3-D, MODFLOW-based model were used to calcu...

The Massachusetts Military Reservation is located in the western portion of Cape Cod. World War II and the period immediately afterward saw the most intense military activity on the base. During this time, chemicals leached into the groundwater and contaminated the aquifer. One of the larger regions, or plumes, of groundwater contamination is the Chemical Spill 10 (CS10) plume, a region in whic...

Recharge is a crucial section of water balance for both surface and subsurface models in resource assessment. However, quantifying its spatiotemporal distribution at regional scale poses significant challenge. Empirical numerical modeling are the most commonly used methods watershed scales. integrated inherently contain vast number unknowns uncertainties, which can limit their accuracy reliabil...
