(2) Definition of Tcv and (Lg+D/2)
図7.2.4 無次元単位図
Instead of Lg+D/2 (Time from the centre of the excess rain
totime of occurrence of on-half volume of hydrograph, Tcv (timefrom
the beginning of rise of net hydrograph to time ofoccurrence of
on-half volume of hydrograph) can be applied .The lag time can be
explained by the following equation.
Tcv = C x (L x Lca / √Sst)0.38
where; Tcv: Lag time. Time from the beginning of rise of
nethydrograph to time of occurrence of on-half volume ofhydrograph
