摘要：Flooding is a natural part of a river's life cycle but it is a major disaster affecting many regions around the world, year after year. Malaysia is among the countries that faces potential flooding problems due to rapid development and, improper river systems. The Skudai river basin covers an area of 293.7 km2 in the south-western part of Johor in Malaysia. The Skudai River has come under the spotlight due to the impacts of future development projects. Land clearing for urbanization and, infrastructure construction may increase the magnitude of flood. Flood risk map is one of the best ways to study and understand the flood behavior. To produce flood level at various locations along the river and flood plain, hydraulic modeling is required to carry out the flood simulation. However, analysis a river system requires tremendous amount of data such as rainfall distribution, river properties and, most important, the flood plain topography. This study presents flood mapping results in Skudai River basin in Johor, Malaysia using InfoWorks software 1D modeling. The tasks involved hydrological modeling, hydrodynamic modeling. Ground model and generation of flood risk map. The results show that eighteen locations are affected by flood of 100 years ARI.
