Hydrologic Analysis and peak discharge determination
Ebissa G. K
Peak discharge Determination is one of the most important studies for Irrigation projects. The proposed of hydrologic design is to estimate maximum, average or minimum flood which the structure is expected to handle .This estimate has to be made quite accurately in order that the project can function properly. To estimate the magnitude of a flood peak the following alternative methods are available academically.
In this study Hydrological analysis has been conducted based on 10years maximum daily rainfall data .The frequency analysis has been carried out by different methods and Log Pearson type III method is adopted .The peak discharge computed by United States Soil Conservation Service (USSCS) method is 1278m3/sec .Since this method over estimates the design flood, we adopt the peak discharge calculated by slope -area method.
Keywords- Hydrologic Analysis, peak discharge Determination, Gusha Temela Irrigation project, frequency Analysis, United States of soil conservation service method.
