SYNOPSIS

Urban  development  increases  flood  risk  in  cities  due  to  local  changes  in hydrological and hydro meteorological conditions. The relationship between the increasing urban runoff and flooding due to increased imperviousness is better perceived than that between the cyclic impact of urban growth and the urban rainfall via microclimatic changes.

Malaysia is a tropical climate country and has high intensity rainfall events. This can lead to flooding especially in urban areas where land surface is covered with impervious materials. With the increasing rate of urbanization, Malaysia as one of the developing countries in tropical region (with high rainfall intensity) has higher chance of being flooded. Therefore, it is important to study the potential flooding impact of such continuous change in land use by a hydrologic-hydraulic model to predict the flood prone areas for different scenarios of land use change and design rainfall.
