Abstract

This study investigates the application of photogrammetric scanning to generate high-quality raster datasets for one-dimensional hydraulic modeling. By processing point clouds, detailed raster files accurately capture open channel morphology. The research evaluates the efficiency, technical complexity, and impact of raster resolution on simulation results using HEC-RAS code. Recommendations address optimizing point cloud processing and selecting raster resolution to balance detail and computational efficiency. The study demonstrates photogrammetry's effectiveness through a one-dimensional numerical model of a nature-like fish pass, showcasing its potential for enhancing hydraulic structure design and monitoring. Results provide insights into future applications in hydraulic engineering.
