摘要：
Linear, exponential and power function regressions were compared for rainfall, runoff and soil loss data. The power function performed better (R2 = 0.77) than exponential or linear functions for estimating runoff from daily rainfall. However, this relationship was improved (R2 = 0.96) by inclusion of a random component to the deterministic part of the function. A linear relationship between runoff and soil loss data performed better (R2 = 0.77) than exponential or power functions. These relationships help in designing soil and water conservation works for supplemental irrigation in the area.
