Flood simulation model using XP-SWMM along Terengganu River, Malaysia
Malaysia is one of the tropical countries in the world with heavy rainfall throughout the year and floods are the most common disaster in Malaysia. Flood simulation model was carried out along Terengganu River for dry and rainy seasons. The result of the simulation shows the water level reached its maximum level at the 1st two hours of the simulation at about 2:40min with the highest flow of Q = 155.90m3/s and velocity V = 1.52m/s. Stationn 1 have the highest value of Q and this because it is at the upstream of the River, while stations 2, 3 and 4 are almost dry because they are at the downstream of the river. Similarly, a 10 years data was also modeled as a secondary data to validate the primary data. This shows that, the simulation was good and XP-SWMM is compatible for flood simulation.
