| Abstract: | The main objective of this writing is to present a practical way to envisage the flood vulnerability in deltaic region, particularly
on the concern of sea level rise. Kuching city of Malaysia is established on banks of Sarawak River, 30 km from the sea. Therefore,
it is subjected to fluvial and tidal floods. Kuching Bay experiences the highest King Tides in Southeast Asia region. These
tide magnitudes could be a glimpse of future sea level rise. By means of modelling these tides, it provides an understanding
and preparation for the impacts of sea level rise on the flood mitigation infrastructures and the city itself. The modelling
efforts had created an illustration that a 10% rise in tide levels would result in increase of flooding areas up to 6% relative
to existing tide levels. |
