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...

Waterlogging refers to the damage plants by water stress due excess soil in crop’s root zone that exceeds maximum holding capacity of field. It is one major disasters affecting agricultural production. This study aims add a crop waterlogging identification module coupled SWAT (Soil and Water Assessment Tools)-MODFLOW (Modular Finite Difference Groundwater Flow Model) model accurately identify p...

Introduction: Groundwater on Mars has been considered to have participated in global flow with the presence of a northern ocean an " inevitable consequence " of early hydraulic and thermal conditions [1,2]. In contrast, we present evidence that an ocean is not hydrogeologically required and that groundwater flow was regional in scale at most. Groundwater Modeling: We seek to test several hypoth...

The continuous aquifers of the Congolese Cuvette basin constitute seat significant water tables reversibly supplying Congo River as well they drain. Consisting mainly sandy-clayey-sandstone formations, these contain groundwater which is main source drinking supply for communities in this sector departments and Cuvette-Ouest. need being more acute, have been subjected to drilling operations orde...

The contaminant transport equation is solved in three dimensions using the Eulerian–Lagrangian Localized Adjoint Method (ELLAM). Trilinear and finite volume test functions defined by the characteristics of the governing equation are employed and compared. Integrations are simplified by forward tracking of integration points along the characteristics. The resulting equations are solved using a p...

Water scarcity in northern Ethiopia, as well its socio-economic relevance terms of water demand for agriculture and domestic use, are at the root search new groundwater resources development models that can be used to control manage resource. The recharge Hormat-Golina sub basin was assessed using WetSpass-MODFLOW coupling. goal this paper is assess sub-basin. These findings then simulate hydra...

An analysis of groundwater flow and transport processes of arsenic in the flow domain of the Yamuna sub-basin located in West Bengal (India) is presented. The objectives of the analysis are: to conceptualize the groundwater flow domain, to determine groundwater flow paths and groundwater velocities, to study arsenic transport in the flow domain, and to study the well captures zones. The first t...
