Modeling of Flood Water Flow: A Review

摘要

A flood is an overflow of water that submerges or drowns land. In general flooding scenario, water levels rise causing areas neighboring water bodies and some road segments in these areas to be flooded and they said two aspects of flooding interest us first, the water body floods reaches a water level higher than normal causing water to flow to the surrounding areas and second, the flowing water interacts with roads, covering road segments. The primary effects of flooding include loss of life, damage to buildings and other structures roadways, and canals. Damage to roads and transport infrastructure may make it difficult to mobilize aid to those affected or to provide emergency health treatment. One of the methods to reduce the velocity of flood water flow across road is to design obstacle objects as diffuser and places it along beside road shoulder. The velocity of water flow will depends on the diffusion pattern of water. The pattern of diffused water will depends on the design of the obstacle objects. This paper will review the impacts of flooding and modeling to protect road flooding.
