Since there is no river gauging station near the road, even for large rivers, rainfall-runoff models are adopted for flood estimation, i.e., for catchment areas less than 50 ha, the rational method is used; for catchment areas, less than 65 km虏, the SCS unit hydrograph method is used; and for catchment areas greater than 65 km虏, HEC-HMS is adopted for flood estimation. <iframe src="https://publications.waset.org/abstracts/188232.pdf" style="width:100%;
