parserasgeo (prg) is a python library for editing, importing, and exporting HEC-RAS geometry files. prg is a work in progress, however most cross section functionality exists. Lines that prg does not ...

HEC-RAS (Hydrologic Engineering Center's River Analysis System) is a widely used software for hydrological modeling and river analysis. One of the critical components in these models is the accurate ...

The USACE Hydrologic Engineering Center continues to enhance modeling, analysis, and mapping utilities of HEC-RAS 5.0 (Beta), as well as HEC-HMS, with its recent release of version 4.1. Many ...

River Geometry & Cross-Section Analysis using HEC-RAS (RAS Mapper) This map shows river alignment and cross-sections extracted over a DEM using HEC-RAS RAS Mapper. The analysis is essential for ...

This paper firstly described the dam break in the aspects of theories and models. Break parameters prediction, the understanding of dam break mechanics, peak outflow prediction were shown as the ...

HEC-RAS is a highly precise model for predicting water levels and flood-affected areas during extreme hydrological events, even with limited input data (Zainal and Abu Talib, 2024); HEC-RAS is widely ...

HEC-RAS is designed to perform one and two-dimensional hydraulic calculations for a full network of natural and constructed channels … steady/unsteady flow, sediment transport, water quality modelling ...

Streamflow regimes significantly influence the geological, chemical, and biological characteristics of the stream 1,2,3,4. Humans have altered the streamflow patterns for water management through ...

Abstract: Scouring refers to the lowering of the level of river bed due to water erosion. Formation of vortices in the vicinity of bridges due to obstruction caused to river flow by piers and ...
