Post-flood forensic analysis on small urban catchment using one dimensional system modelling

A 0.47 km2 of residential houses in Sungai Mr;rah (SM) in the Sibu Town of Sarawak State is located within the Seduan River basin, which is a flood-prone area with relatively flat and typicaJly low-lying floodplain. Poor maintenance, severe conditions and water logging in the current drainage sys...
