DEVIATION OF TIME OF CONCENTRATION

Generalized expressions for the time of concentration are derived from the kinematic wave theory. Two types of geometric configurations are considered in the derivations: (1) rectangular plane section and (2) converging section. It is shown that under very special conditions the well-known Kirpich's formula for the time of concentration is a special case of the generalized expressions. Furthermore, it is shown that the rainfall duration has definite influence on the time of concentration--a fact that apparently has not been considered before. /Author/
