碩士 === 逢甲大學 === 水利工程與資源保育學系 === 106 === In this study, the Digital Surface Model (DSM) built by the Unmanned Aerial Vehicle (UAV) uses the SketchUp and InfraWorks software commonly used in Building Information Modeling (BIM) to match the two-dimensional river transition model of the NCCHE-CCHE2D conducts water analysis, and displays the visual and BIM combined with the flow, and then introduces the numerical model of stream water transport sand to simulate the water depth and flow velocity changes when the water flows through these engineering entities. It is the primary work of this research to present the realistic animation of CCHE2D closer to the real environment. This study draws the following conclusions: 1. In this study, the unmanned aerial vehicle UAV was used to capture the converted topographic data. Because the river channel is a bare ground without vegetation cover, the digital surface model (DSM) can be used to display the three-dimensional topography of the real river channel by InfraWorks. 2. This study uses InfraWorks software, which is similar in nature to the GIS geographic information system. It is a display platform with high compatibility. 3. The type of wild stream project in this study was constructed using three kinds of projects, and simulated and displayed at different flow rates of 150, 1500 and 3000 cms. The results can effectively show the flow velocity and water depth change when the water flows through the structure.
