Vulnerability, Flood, Downstream, KubanniAbstract
Biophysical flood vulnerability analysis of downstream communities was conducted in the study area was classified into low, moderate and high flood vulnerable areas. The size of farmland declined from 6.222km2 in 1990 to 5.433km in 2020. The result also shows that the total area liable to flooding is about 5.477km2. The finding show that the floodable area increased in area extent from the dam breach outlet to the downstream outlet of Kubanni basin. Given percentage of the downstream area of the dam are highly vulnerable because of the flat terrain especially Tudun Wada, Sabon Gari and Gyallesu to the confluence with the Galma River.
