Inundation Mapping and Flood Frequency Analysis using HEC-RAS Hydraulic Model and EasyFit Software
Journal of Water Management ModelingConducting a flood frequency analysis and mapping of the inundated area in rivers are important for river flow modeling. The main purpose of this research is to estimate the peak flow, model the inundated area using HEC-RAS, and conduct an analytical ...

Dam breach modeling using HEC-RAS and GIS
Obras y Proyectos, 2009 A flood caused by a dam breach may be much larger in magnitude and behave much differently than a natural flood. Mapping sucha flood wave requires an accounting of hypothetical conditions that could lead to a dam breach, as well as extreme flow dynamics downstream of the breach.

Use of the HEC RAS model for the analysis of exceptional floods in the Ouémé basin
Proceedings of IAHS. The Ouémé River basin extends over almost half of Benin's territory, entirely located in a humid tropical climate. This river system includes a deltaic zone (delta of the Ouémé) known for its high agricultural potential and thus subject to a socio ...

Optimisation of hardware setups for time-efficient HEC-RAS simulations
Cambridge Prisms: WaterThe necessity for high-resolution two-dimensional (2D) simulations in flood modelling often requires excessively long simulation times. This study evaluates the impact of various hardware configurations on Hydrologic Engineering Center-River Analysis ...

基于HEC-RAS和MIKE 11模型的岗头河水面线计算对比分析
Renmin Zhujiang选取岗头河为典型案例，分别采用HEC-RAS和MIKE 11开展水面线计算研究，分析2种模型在该流域的适用性、计算精度及各参数敏感性差异。结果表明，MIKE 11计算的岗头河水面线精度更高，其纳什效率系数和平均绝对误差均优于HEC-RAS，在研究区域的适用性更强。MIKE 11对坡降减小更敏感，HEC-RAS对坡降增加更敏感；HEC-RAS对流量变化更敏感；两模型对糙率变化均不敏感。研究成果为岗头河的防洪治理工作以及类似中小型河流在水面线计算模型的选择提供参考，可为防洪规划和治理决策提供参考。
