During the initial phase of the project, a comprehensive urban flood risk map was created using GIS and HEC-RAS. This map encompasses both the river and the expansive Guyuan metropolitan area, spanning over 150 square kilometers. The model effectively captures crucial data points like flood velocity, inundation areas, duration, and other vital information, laying a strong foundation for informed decision-making and effective flood mitigation strategies.
Thanks to the valuable support from the local government and survey department, we were able to obtain high-definition raster data to accurately depict the site’s topography. With a resolution of 0.5m, which surpasses the standards of typical projects, this detailed topographic information greatly benefits all phases of the project, including design and implementation.
The visualization of modeling results plays a crucial role in enhancing the understanding of flooding issues, particularly for clients. This clear visualization becomes a pivotal factor in obtaining approval for necessary mitigation measures.
