WebUnit hydrograph derivation is done by using different rainfall input i.e. single station, rainfall catchment and inverse effective rainfall derived based on hydrograph alone. The resulted unit hydrographs are then used for design flood calculation. Results show that the resulted unit hydrographs vary among the different rainfall inputs. The WebDrainage density is a quantity used to describe physical parameters of a drainage basin. First described by Robert E. Horton, drainage density is defined as the total length of channel in a drainage basin divided by the total area, represented by the following equation: [1] The quantity represents the average length of channel per unit area of ...

WebLevel hydrographs can only be applied at an outfall node. The level hydrograph is used to represent changes in seawater or river level that cause backflow into the network. Note If a level hydrograph is applied to any type of node other than an Outfall, it will be ignored during simulation. Webhydrographs. The results indicate that sediment transport during the falling limb was lower than during the rising limb in all of the three types of hydrographs. This reduction is more evident for the low-magnitude hydrographs. The grain size of the bed remained virtually constant throughout the hydrographs but the grain size of transported
