Assessing Flood Susceptibility Areas in the Revúboè river sub-basin, Mozambique

Abstract

This study assesses flood susceptibility in the Revúboè River subbasin, Mozambique, using the Analytical Hierarchy Process (AHP) and Geographic Information Systems (GIS). Five conditioning variables – slope, hypsometry, land use, soils, and rainfall – were integrated to produce a flood susceptibility map. Results
indicate that 55% of the basin has high to very high susceptibility, concentrated in low-lying areas near Tete and Moatize. The analysis supports land-use planning and disaster risk reduction, providing valuable insights for managing flood-prone areas in the Zambezi basin.
