| dc.description.abstract | This paper deals with a formula for estimating the concentration time in a river basin, the-oretically and practically. The concentration time is defined as the time required for disturbanceof rainwater to propagate from the top of slope located at the remotest portion of the basin in thesense of dynamics to the outlet. Based on this definition, the equation for the concentration timeis derived from the kinematic wave theory to emphasize being a function of the average effectiverainfall intensity or peak discharge and of the area of watershed. By applying an approximatemethod to estimate the concentration time, the hydrological data in 18 natural river basins of0.13-740 km2 are examined to propose a practical formula for the concentration time. Theformula is also modified to extend its applicability to grazing and urban watersheds. | en |
