Numerical Modeling Of One-Dimensional Overland Flow Over Porous Surface

Due to rapid urbanization, surface water drainage systems are designed to perform as natural drainage acting as water storage areas that allow infiltration and evaporation. Furthermore, in order to solve issues caused by traditional drainage systems, there has been an increase of attention on Sustai...
