The Mono River in the Yoto district, presents a challenge in terms of repeated flood hazard.
The eight selected communities lie in majority in the floodplains of the Mono River and
experience year after year flood disaster. This study focuses on flood vulnerability
assessment of the downstream part in the Mono River basin in the Yoto district. It analyses
the trend in rainfall and river discharge series (1971-2010); it assesses the determinants of
flood vulnerability; and it equally computes Flood Vulnerability Index (FVI).
The result reveals a clear evidence of change in precipitation and river discharge
patterns during the period of record. It shows an extreme variability in terms of flood
magnitude and frequency in the Mono River. Besides, the closeness of households’ farmlands
to the river body, the type of construction and the position of settlements, the household size,
the low level education of household head, the lack of diversification of livelihood strategies,
the lack of adequate flood warning system and lack of willingness and ability to take
responsive actions coupled with inadequate emergency services, are identified as main
determinants increasing communities’ vulnerability to flood disaster. Furthermore, FVI offers
easy comparison of communities’ vulnerability to flood disaster.
