Accurate computation of runoff amount from a watershed is difficult, as it depends on several factors concerned with the atmosphere and watershed characteristics, to evaluate which effect on runoff is not so easy. On the basis of field experiences and observations, the following methods are frequently used in the field of soil and water conservation for estimating the maximum or [...]
