Abstract
Downstream control of turbidity currents resulted from turbid water inflows into a well-mixed reservoir by the use of a fence placed before a dam has been investigated experimentally, as a countermeasure to water quality control as well as sedimentation due to turbidity. In this study, the effects of fence deformation due to pressure differences between inside and outside of the fence upon the effects of displacement efficiency are considered as well. It is found that the fence is capable of effectively displacing the inflowing turbid water out of the reservoir, while maintaining the position of plunge point in stable condition. It is also suggested that deformation may degrade fence performance when the position of the fence is far shifted from original setting position.
