Research on the key points of revetment design in water-deficient areas

Jing Gao, Jitong Xie
The design of river revetment is a difficulty in the landscape design in water-deficient cities. This paper analyzes the problems in water revetment’s adaptive design in three different aspects, which are flood control, ecological compensation and water self-purification. Following the principle of “ecological...
