Remote sensing and Geographical Information System using for Water Resources Management for Bandama Watershed (Côte d’Ivoire): Case study of Kohoua Subwatershed at Farandougou

Abstract

Nowadays, studies on water resources management are quite important. This study on a subwatershed of the Bandama River in Côte d’Ivoire got a better understanding of the geomorphological characteristics of the study area. The use of satellite images and geographic information systems tools allowed to respond appropriately the management of water resources. The Digital Elevation Model (DEM) of the Farandougou subwatershed, the Bandama river hydrographic network and the geostatistical analysis of this subwatershed have been shown and interpreted in this study. The area’s elevation is between 0 and 700 meters approximatively. The value of river length minimum is around 11273.091 meters and the value of river length maximum is around 44415.180 meters, the coefficient of variation is around 0.462 for example. The geostatistic of Kohoua at Farandougou has given also mean of 449.621 meters, mediane of 441 meters, variance of 3040.996 meters and standard deviation of 55.145 meters. The majority of the Kohoua subwatershed area has an elevation around 410 meters versus the minority around 715 meters.
