Abstract

Peak runoff determination is one of the most important studies for the design of hydraulic structures which is used for different purposes like irrigation, water supplies, hydropower, and bridge structure. The amount of runoff produced and rainfall received determine the development of water resources in any region. The purpose of hydrologic design is to estimate the maximum, average, or minimum flood that the structure is expected to handle. Hydrological analysis has been conducted based on 33 years of maximum daily rainfall data. An important step in the analysis of rainfall occurrence is to choose an appropriate distribution to represent the depth of rainfall to study rainfall. Nekemte meteorological station was used for maximum rainfall estimation by gumbles distribution method of 50 & 100 years return period which is 132 & 142mm; while for generation of peak runoff by using soil conservation service (SCS) method which is 238 & 263m3/s respectively for Basaka sub-watershed. Conversely, the SCS method is recommended to estimate the ordinate required for the development of peak runoff hydrograph in the river sub-watershed because it utilized additional morphometric parameters such as watershed slope and the curve number (CN) which is a function of the properties of the soil and vegetation cover of the watershed. Basaka sub-watershed delineation analysis was done by GIS 10.8 and it covers a drainage area of about 58km2.
