INTEGRATING GIS AND AHP METHOD FOR EROSION VULNERABILITY DETERMINATION FOR LABIOD WATERSHED (EASTERN ALGERIA)

Full text

Abstract:

The LABIOD Watershed is a space of high vulnerability to soil erosion which causes an irreversible situation of desertification. This study illustrates the combination of analytic hierarchy process (AHP) with geographic information systems (GIS) to resolve the complicatedproblem of soil erosion in this semi-arid area. In this paper, pair-wise comparisonmatrixes and consistency ratio in a multi-criteria analysis method are computed in IDRISI Selva software by using GIS with Revised Universal Soil Loss Equation (RUSLE) model. As the result, consistency ratio (CR) was very significant and highlights the advantages of this application in the determination of vulnerability to erosion which constitutes a decision making toolfor adjusting necessary protection measures.
