2.1.2 Flow equations-confined and unconfined aquifer (2D) The governing equation describing the flow in a 2D nonhomogeneous confined aquifer is given as (Bear, 1979): (4)∂∂xTx∂h∂x+∂∂yTy∂h∂y=S∂h∂t+Qwδx−xiy−yi−qs The governing equation describing the fl...
The challenges in the paper include: (i) the study area comprises confined and unconfined aquifers and (ii) Artificial Intelligence (AI) is used to run Multiple Framework (AIMF) in order to map specific vulnerability due to a specific contaminant. Predicted results by AIMF are referred to as...
An aquifer is a layer of permeable sediments or rocks found underground that holds groundwater, whereby the permeability of the rock is dependent on its porosity and capacity to retain water. Water can be pumped from an aquifer by forming a well....
