  Drainage problem in Beles Sugar Project is becoming severe during rainfall season that the effective rainfall was greater than the sugarcane water requirement and higher area coverage of vertisols. To remove this excess rainfall through installations of surface drainage system, this study was conducted to estimate design rainfall in magnitude and recurrence interval based on the recorded maximum rainfall. The independent, homogeneity, and outliers of the recorded data were tested accordingly. Probability of exceedence and return periods for daily maximum rainfall was determined using Kimball’s method. Gumbels method was used to compute design rainfall of different desired return period. The relation between observed and computed data was undertaken using regression function. Thus, recorded rainfall data was independent and homogenous at 5% signifance level. Also there was no val.. Read More»
