Flooding is one of the most frequent and widespread of all environmental hazards and of various types and magnitudes, occurs in most terrestrial portions of the globe. The downstream of Shiroro dam has been experiencing recurrent floods resulting in the destruction of properties and loss of lives. Consequently, the study aims at mapping flood risk and vulnerability areas downstream of shiroro dam. Topographic maps, soil maps, geology maps, demographic data, and digital elevation models (DEM) were used. These data were analyzed using pair-wise evaluation techniques for decisive weighted-overlay investigation of each factor in flood vulnerability assessment. The result shows that 6.4% of the study area was highly vulnerable, 64.02% was moderate and 29.58% was low. The study highlights the application of GIS in modeling flood risk in the Down Stream of Shiroro Dam and its Environs. Vulnerability assessment critical because it provides an organization with details on any weaknesses in its environment.
