Download and install Hec-Ras, then explore its menu-driven interface and geometry tools for flood modelling using an example project to view river plan, cross sections, and roughness parameters.
Explore Hec-Ras flow theory: continuity, uniformity, energy balance, normal depth, water surface profiles, specific energy, critical depth, and Froude number for subcritical and supercritical one-dimensional steady flows.
Learn to set up a basic HEC-RAS project from geometry and cross sections to steady-flow analysis, including units, river reach creation, boundary conditions, and simple results visualization.
Set up a Hec-Ras project, define the river reach and cross section with Mannings roughness, then run uniform flow to compute slope, discharge, or water surface elevation.
Explore HEC-RAS boundary conditions for steady flow, including known water surface, normal depth, critical depth, rating curve, and subcritical, supercritical, or mixed flow at upstream and downstream limits.
Learn to add a bridge in HEC-RAS between sections 05 and 06, design platform, columns, and abutments, save geometry, run steady-flow analysis, and observe changes in water levels.
Explore Ras Mapper, the 2D unsteady flow tool added in HEC-RAS version 5, and learn to load terrain, create a 2D flow area, and generate a mesh.
Learn to generate geometry in Hec-Ras with Ras Mapper by loading a digital terrain model, digitizing river and cross sections, and editing banks and flow paths.
HEC-RAS is a program of the United States Army Corps of Engineers, for the modeling of floods in natural rivers and other canals. In this introductory course we will see the process for the realization of one-dimensional models, although as of version 5 of the program, two-dimensional flow modeling has been incorporated, as well as sediment transfer modeling capabilities.
The course will advance through the entire process of generating the model: from the creation of geometry, analysis data entry, model execution, and data export. #AulaGEO
It is an eminently practical course with just and necessary doses of theory, where materials are provided to follow each lesson in real time.
HecRas is a program for the calculation of floods and floods.
