Physical Modelling for Flood Evaluation of Selangor River Under Tidal Influence
The estimated area exposed to flood disaster in Malaysia is estimated around 29,000 km2 or 9% of the entire country, affecting approximately 15% of the total population. The purpose of this study is to developed a physical model under tidal influence for Selangor River and to assess the floodplain and water level for various flow conditions with and without tidal influence. The model was developed utilising a non distorted scale of 1:100. The test was carried out for various flow with (i) fixed low water, (ii) mean sea and (iii) high water, with and without tidal influence for all cases. The results showed that the water level increases as the the flow increases and causes the flood. Flooding does not occured at downstream under all conditions tested.

The model was developed utilising a non distorted scale of 1:100. The test was carried out for various flow with (i) fixed low water, (ii) mean sea and (iii) high water, with and without tidal influence for all cases. The results showed that the water level increases as the the flow increases and causes the flood. Flooding does not occured at downstream under all conditions tested.
