This study highlights the simulation of tsunami cases using HEC-RAS 6.1. The primary aim is to evaluate capability software in performing due its standalone computational framework (pre-processing, execution, and post-processing stages), making modeling process interactive. model accuracy was tested against some benchmark wave propagation, including analytical solutions, laboratory experiments,...

The application of numerical models to understand the behavioural pattern a flood is widely found in literature. However, selection an appropriate hydraulic model highly essential conduct reliable predictions. Predicting discharges and inundation extents are two most important outcomes simulations stakeholders. Precise topographical data channel geometries along suitable required accurately pre...

River renaturation can be an effective management method for restoring a floodplain’s natural capacity and minimizing the effects during high flow periods. A 1D-2D Hydrologic Engineering Center–River Analysis System (HEC-RAS) model, in which flood plain was considered as 2D main channel 1D, used to simulate flooding restored reach of Spree River, Germany. When computing this finite volume diffe...

Abstract The hydrodynamic model is essential for building a water quality rivers, lakes, estuaries, and other systems. Most software, such as HEC-RAS, can perform complex surface body limitations to represent the corresponding area. In contrast, models, like WASP, simulate wide range of contaminants in multidimensional geometry reservoirs. Still, it requires flow information from separate model...

Abstract Extensive impervious area and the man-made streams are characteristics of urban areas. In recent years, rapid urbanization has led to change rural areas into areas, runoff will increase as result spread growth Land use changes, increasing urbanization, unauthorized construction, inefficiency sewage system increased surface in have significant impacts on inundation hazard. Therefore, ma...
