Hydraulic experiments of urban river meandering method and fish habitat revitalization
Abstract Recently, the number of urban river restoration projects that use artificial spurs to create ecologically sound rivers has steadily increased. In this study, the effect of spur placement on improving the ecological environment of rivers is investigated for an optimal riverbank spur design based on small-scale experimental results. The experiments were conducted by varying the placement of the spur formations, the spur types, and the dimensionless Froude Numbers. Stone mattress, wickerwork, and combinations of these materials were used as spurs. The experimental results show that the spur placement helped create a gentle meandering river and secured the fish habitat. A combination of stone mattress and wickerwork (wickerwork beneath a stone mattress) resulted in the most effective type of spur for achieving a gentle meandering and sound fish habitat. The average water flow velocities in front of the spurs decreased by roughly 30%, while the average water flow velocities behind the stone mattress decreased by approximately 70%. Consequently, it is concluded that the well-implementation of spurs could induce an ecologically favorable habitat for fish and fish spawning.
