Abstract EN
This paper presents the evaluation of methods of determination of peak runoff for an ungauged catchment.
The present study made use of Geographical Information System (GIS) for the morphometric analysis of four sub-catchments within Jere sub-basin in Gurara Basin, Nigeria.
Various morphometric parameters were computed and analyzed as sub-basin characteristics are important factors in determining the runoff.
Three methods of peak runoff estimation were used to determine peak runoff of the study area for four return periods.
The results of the peak runoff estimation based on rational method for the four sub-catchments for 25-year, 50-year, 75-year and 100-year return periods varied between 224m3 /s and 1036m3 /s, while the results for the SCS method varied between 105.3m3 /s and 162.05m3 /s and the results from the Cypress Creek method varied between 22.8m3 /s and 86.55m3 /s.
The results obtained from the three methods showed that there are significant differences in the peak runoff results and also there are significant differences in the peak runoff results for the different return periods.
