Groundwater Potential Simulation in a Virtual Geographic Environment (VGE)

Abstract

A 3D approach for modelling and simulation of aquifer water yield potential based on AHP, 3D GIS and VES is employed. Fault density, lithology delineated from overburden resistivity survey and surface slope were considered as direct factors that influence the aquifer water yield potential. Using AHP techniques the normalized weight of fault density obtained for fault is 24.31%, 66.87% for lithology and 8.886% for slope. 3D TEN data model was used in 3D modelling of the different subsurface geology according to the assigned weight of the parameter as they influenced aquifer water yield potential. The simulation results show high water contribution when overlay by weathered material follow by sand layer and clay sand layer. The least contributing factor to aquifer water yield potential is clay sand. The used of 3D GIS, VES and AHP techniques in 3D modelling and simulation of aquifer water yield potential will help policy makers and government in groundwater resource planning, management and exploration to meet societal demand while maximising resources.
