Abstract
The right estimation of catchment peak flow due to a specific storm is very important. Based on the estimated peak flow, drainage and flood protection systems are proposed and designed. Meteorological data such as storm characteristics and storm return period are main factors that affect runoff hydrograph and peak flow discharging from a catchment.
The main objective of this research is to study the effect of storm kinematics i.e. storm speed and direction on the modelled runoff hydrograph using a 2D model. The computations have been carried out using InfoWorks Integrated Catchment Modeling (ICM) software.
The runoff hydrograph of the study catchment is estimated under different scenarios such as:
• The catchment is subjected to a commonly used stationary rainfall Storm (Without spatial Distribution).
• The catchment is subjected to a moving rainfall storm
o In the direction of flow (downstream)
o Opposite to the direction of flow with the same speed (upstream)
o In the direction of flow with higher speed (change in speed)
• The catchment is subjected to a stationary rainfall storm (with spatial distribution) in order to evaluate the effect of simulating rainstorm spatial distribution separately.
Storm characteristics (such as rainfall total depth) are kept the same for all scenarios. As-Sulai catchment, located in Riyadh, Kingdom of Saudi Arabia KSA, is used as a case study.
