This runoff provides about one … WebThe runoff coefficient is the percentage of rainfall that becomes runoff (and river discharge) during a storm, and it has a relevant role in engineering practice. It is, in fact, a key parameter in the so called "design-storm" method, in which hypothetical storm events of a given return period are transformed into flood discharges that are assumed to have the same return …
