A dataset for the flood vulnerability assessment of the upper Cross River basin using morphometric analysis
The on-site collection of data is not only time consuming, but
expensive and perhaps near impossible in restive communities
within the upper Cross River basin (UCRB). Therefore, the importance
of this data cannot be overemphasized. This article presents
a Digital Elevation Model (DEM), land use and land cover (LULC)
map, soil map, geology map and climatic datasets which enhance
the understanding of the physical characteristics of the upper
Cross River basin using morphometric analysis. The use of the
LULC map, soil map and the DEM in conjunction with the climatic
data enhance the creation of the Hydrologic Response Units
(HRUs) and the water balance modelling. The simulation of the
water balance at the HRU level enables the routing of the runoff to
the reaches of the sub-basins and then to the channels. The geology
map provides confirmatory information to the morphometric
analysis. The compound factor computed from all the
derived morphometric parameters enhance the determination of
the overall flood potential of the congruent sub-basins
