APPLICATION OF GEOGRAPHIC INFORMATION SYSTEM IN FLOOD CONTROL AT YOLDE PATE, YOLA ADAMAWA STATE

Muhammed I, I Sarkinzango, A Aliyu

Abstract


Geographic information system a computer based tool for mapping and analysis was used to determine the flood risk zone in Yolde Pate. A base map made from a topographical map of the study area. From the base map created, the digital elevation model (DEM) was generated by digitizing on the screen the contour lines. An appropriate, module of the ILWIS software was used to interpolate for immediate value of the digitized contour lines. The overall result of coverage (map) which is a digital elevation model (DEM) of the study area was made. From the study carried out and the analysis of the result obtained, it has been clearly revealed that the flood risk (prone) coverage in Yolde Pate is about 47.89% of the entire study area and only 40.04% is less potential to flooding while 12.07% is moderate good. Based on these results, appropriate recommendations are made that will assists the policy makers to make a sound decision on how to deal with situation in this area.
