Abstract

Navsari is a developing, thinly populated city located on the bank oh river Ambica. The frequent flooding in Navsari city has become a recurrent phenomenon of last decade. The city has faced frequent flooding since long back. Major flood event occurred in year 1981, 1984, 1994, 1997, 2001, 2003, 2004, 2006, 2013 and 2014. At present, the carrying capacity of the river is approximately about 2.5 lakh cusecs (7071 cumecs). The flooding problem in the Navsari city has been perennial each time causing a reversal of gains on economic and social development. This paper presents a model developed to determine water level along the Ambica river from Ichhapur to 11 km Dhamdachha village using the HEC-RAS hydrodynamic model and past flood events of the year 1984, 1994 and 2004. The study reach consists of 359 cross-sections. The model was calibrated and verified for steady flow conditions. It provides water levels and inundation areas along the river for different discharges. The study compares the result obtained from the model with the help of observed flood level taken during past flood events. Based on the above study, it is strongly recommended to construct a retaining wall or either raised the height of the existing wall at a particular cross-section.
