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...

land surface parameterization schemes are one of the most important components in gcm and nwp models. these schemes calculate the exchanges of momentum, mass and energy between land surface and the atmosphere. runoff is one of the important components in the water cycle of the land surface scheme whose parameterization is difficult because of complexity in the processes governing the runoff gen...

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...

Abstract The multi-aquifer system of the Nubian aquifer in central Sudan hydrogeological was simulated using a three-dimensional steady-state model. goal study is to detect effect pumping on groundwater flow and thus, productivity. conceptual model area built based available geological data guided by geophysical survey. Processing MODFLOW numerical code used calculate hydraulic head water balan...

in this paper, we study the existence of coupled coincidence andcoupled common fixed points for single-valued and fuzzy mappingsunder a contractive condition in metric space. presented theoremsextend and improve the main results of abbas and$acute{c}$iri$acute{c}$ {itshape et al.} [m. abbas, l.$acute{c}$iri$acute{c}$, {itshape et al.}, coupled coincidenceand common fixed point theorems for hybr...

Regarding to increased use of groundwater resources, it seems necessary to have more accurate knowledge of characteristics of aquifers in order to improved usage and accurate management of these resources. In this study, we simulated groundwater flow of Qazvin aquifer usingVisual MODFLOW model, collecting data and statistics, as well as using different studies. The simulation model has operated...
