摘要: AbstractAn analytical solution for overland flow under (upstream and downstream) moving storms that uses Laplace transformation to solve the one-dimensional (1D) linear kinematic wave equation is presented. This solution, which corresponds a single continuous function total space-time domain of hydrograph, enables evaluation discharge over time drainage plane surface. The result was compared with another numerical simulation, experimental runs using laboratory flume. comparison showed very good fit, proposed thus regarded as validated. By applying model hypothetical catchments storm patterns, distinct hydrologic responses upstream downstream were identified.
