COMPREHENSIVE SEDIMENT CONTROL MANAGEMENT IN MOUNTAINOUS WATERSHED USING SMALL UAV AND NUMERICAL SIMULATION MODEL

Abstract

It is important for improvement of flood control and environment in river basin to control sediment outflow using prediction and monitoring of sediment outflow in a mountainous watershed. For comprehensive sediment control management in river basin, numerical models to predict flood and sediment outflow have been proposed; however, these models have not been used on previous SABO action plans. On the other hand, the air photo survey has been cheap and easy to use practical Unmanned Aerial Vehicle developing technology of gyro sensor and electromagnetic motor of UAV. In this paper, we predicted flood and sediment outflow based on rainfall, topographical conditions and SABO dams using previous numerical models for mountainous watersheds. Furthermore, the new survey method of sediment outflow in mountainous watersheds using small UAV was proposed.
