Abstract—Rivers are seldom straight. Depending on discharge, slope and sediments, some stretches are meandering with alternate bends while some stretches are braided with main and branches within the same flood plain. Usually a river is found to erode the outer bank and sediments get deposited on inner bank and thus causes major problem of that particular region. In the present study this problem has occurred frequently in Vellar River in Cuddalore District at every monsoon. Spur and retaining wall has been designed with the help of IS codal provisions and existing methods adopted by Experts and Engineers of PWD, Govt. of Tamil Nadu. It has been found that some modifications in design, care during construction and maintenance would enhance the performance of the spur. The construction of RCC spur will not only protect the river bank but also the adjacent patta lands and cultivable lands in the study area. 

Index Terms—discharge, environment, flash floods, impermeable spurs, meandering, retaining wall
