Erosion of bed and banks of rivers is a problem of great concern in India and abroad. A meandering river generally erodes the outer bank and deposits the sediments on the inner bank. Protection of riverbank, also termed as river restoration, thus becomes a necessity in such reaches of a river where scouring of banks and bed material leads to change of course of the river, thereby causing loss not only to land and property, but also to flora and fauna of the region. Porcupine systems have been found to be successful in big Indian rivers such as Ganga, Brahmaputra and Kosi as a cost-effective measure for river restoration. In this chapter, sediment trap efficiency of porcupine systems has been studied with laboratory experiments. Sediment trap efficiency of porcupines is found to be higher for low submergence and high sediment concentration. A comparison has been made in between the conventional triangular/tetrahedral porcupines and a relatively new prismatic design. Various configurations of layout of porcupines have been investigated to gain an insight into the sediment deposition pattern for a particular discharge, water depth and sediment concentration of the river. Performance of prismatic porcupines is found to be almost similar to that of conventional porcupines, although they comprise nine members in contrast with the triangular porcupines, which consist of six members only. Trap efficiency of conventional porcupines in capturing sediment is found to be as much as 82%, whereas in case of prismatic porcupines, maximum trap efficiency is found to be 74.26%, other parameters being the same. Therefore, the use of prismatic porcupines is rather not advantageous for erosion control or reclamation. Also, they are economically more expensive since they require nine members instead of six. However, they can prove to be safer and better at trimmed bank slopes of rivers.
