MORPHOMETRIC ANALYSIS OF URBANISED SUB-DRAINAGE BASINS OF ASA RIVER CATCHMENT IN ILORIN, NIGERIA

Abstract

This research work analysed morphometric properties of four urbanized sub-drainage basins of Asa river catchment in Ilorin. Data for the study were generated from florin North West topographical sheet. The extracted data were subsequently subjected to various statistical analyses. Results obtained indicate that the studied basins exhibit high variability in values of morphometric parameters. Correlation matrix generated reveals that basin area exercises a tremendous influence on other morphometric parameters. The study thereafter recommended a number of ways towards reducing environmental disaster of flooding induced by basin characteristics.
