Abstract

Floods are natural disaster; they cause the losses and damages to lives, properties and the nature. The main objective of this study is to integrate science of meteorology, hydrology and hydraulics by using an appropriate and effective method in flood management. 1-D Hydrodynamic model is used to evaluate geomorphic effectiveness of floods on lower Tapi river basin. In this present study, geometry of lower Tapi River, flood plain of Surat City and past observed flood data have been used to develop 1-D integrated hydrodynamic model of the lower Tapi River, India. After collecting the entire data using 1-D hydrodynamic model to simulate the flood of year 1968, 1998, 2006, 2012 and 2013. As Surat city has faced many floods since long back. Major flood event occurred in the year 1883, 1884, 1942, 1944, 1945, 1949, 1959, 1968, 1978, 1979, 1990, 1994, 1998, 2002, 2006, 2007, 2012 and 2013. The carrying capacity of river is approximately about 4.5 lakhs cusecs (12753 cumecs) at present. The river network and cross sections for the present study were extracted from the field surveyed contour map of the river Tapi River. In this, stability of a segment of lower reach of Tapi river approximately 6 km length between Weir cum causeway and Sardar Bridge is evaluated for its carrying capacity and geomorphic effectiveness. The study reach consists of 24 cross-sections. The model is used to evaluate steady flow analysis, flood conveyance performance and uniform flow analysis. The study area selected is highly affected by the flood and it is necessary to develop flood reduction plan for the study area which will helps to control a big disaster in future. The recommendations are done based on this study either to increase height of the retaining wall or construct a retaining wall at certain sections along study reach. The present study also recommends improving carrying capacity of Tapi river so that it will minimize the flood in surrounding area of Surat City.
