Three-dimensional Modeling for Deformation and Movement of Siltfence in Water: Coupled Simulation of Water Flow and Siltfence

Abstract

Abstract. Siltfence is a curtain-like structure to prevent the spread of suspended pollutants generated by constructions in rivers or coasts, and its shape deforms horizontally and vertically. In this paper, we propose a modeling method to simulate the siltfence deformed in the two directions by coupling with water flow dynamics. We preform numerical simulations on a siltfence installed in flume using the proposed method, and we confirm its validity by comparing between the simulation and flume experiment.
