چکیده:

Lowering the cost of flood damage in rural floodplain in compare with urban floodplain and making more space to pass the flood into the river corridor are two main reasons of re-look on rural floodplain development strategy. In rural floodplain the flood damage related to time and quality and quantity of crops would change per unit area and different crops make changes on different Annual Recurrence Interval of flow (ARI). Some of crops show more sensitivity in lower discharge and some make more sensitivity in higher discharges. This paper makes an analysis on flood hazard changes of crops totally and separately and explains about sensitivity of crops to flood damages in different ARI using a special software for Flood Hazard Risk analysis in Malaysia Rivers. The analysis applied for limited reach of Bernam River in Malaysia. The input data contain some hydraulic and hydrology data such as depth, duration and flooded area for crops in different ARI and the output of this software shows the flood damage of crops totally and separately and how the behavior of oil palm, rubber and other tree crops are different in different ARI
