Contribution of GIS and remote sensing in evaluating groundwater potential zoning in Mbandjock

Abstract

Geographical information systems present today an undisputed advantage for the management of natural resources to facilitate their management. As a matter of fact, this study aims to evaluate the water potential in the water tables of Mbandjock using the multivariable analytical hierarchy process method applied on GIS. To do so, we first determined the different contributing variables: in this study, we use drainage density, rainfall distribution, soil geology, variation in slopes, soil type, land use, and lineament density. Once the different factors were mapped and reclassified, which led us to the second part of this work, where it was a question of overlaying these different variables by associating each variable with a weight value proportional to its importance in relation to other variables. This led to the production of a distribution map of groundwater potential.
