Flood Control and Prediction of Flood Using HEC-RAS ????? A Review

Flood is very common in India. Many parts of the country influenced because of the flood.76 % of rainfall out of rainfall total calculated and distributed on the earth surface. Surat is the main city of Gujrat. In rainy season Surat city highly affected due to flood. Flood is the major problem of Surat city. Flood is occurring in Tapti River during monsoon and influence many area. Flood is responsible for property and live losses. HEC-RAS Hydraulic Engineering Centers Analysis System is the software which is used for controlling flood. HEC-RAS is the advance computing technique gives flood warnings govern water flow and compute water surface profile. Various one dimensional hydrodynamics models using for calculating flood event. Simulation of floods 30 years past flood data were addressed in present study. Cross-sections extracted from Auto-Cad file of lower Tapti River.
