HEC-RAS is a software designed to perform hydraulic 1D and 2D calculations on river channels either natural or man constructed. It allows steady flow, unsteady flow, sediment transport and water quality modelling. It is developed by the US army corps of engineers, US Department of defence and it is openly available software. The HEC-RAS steady flow is based on one dimensional energy equation, while for the unsteady flow, HEC-RAS uses an implicit, finite difference method to solve the fully dynamic Saint-Venant equations.
The objective of HEC-RAS is to solve river dynamics and river engineering problems. Applications are delimitation of flood areas, embankment and protection work design, river restoration, emergency plans for dam break, optimization of hydraulic work and risk assessment and management.
This course aims:
- The students get familiar with Hec-Ras Interface,
- The students understand the Software’s tools and functioning,
- To simulate different inflow case scenarios and
- To simulate river dynamics and understand the interaction with hydraulic structures.
The course consists of a total of 12 hours. The contents of the course are separated in 6 lessons as follows:
- Installing Hec-Ras
- Presenting the Software capabilities.
- Presenting the Software Interface.
- Use of QRas to obtain the geometry of the Cross Sections.
- Importing the River Geometry to Hec-Ras.
- Entering Flow Data details.
- Use of Boundary Conditions.
- Entering geometry information of the cross sections of the river and create a river confluence.
- Realize hydraulic calculations.
- Representing a river model where there exists a river confluence.
- Representing steady water depth profiles for the different flow scenarios entered.
- Realize a hydraulic model adding a hydraulic structure (culvert) to the river system,
- Entering geometry information of the cross sections of the river,
- Hydraulic analysis of the water depth profiles on cross sections and on the longitudinal profile of the river.
- Realize a hydraulic model adding a reservoir into the river system and evaluate the long-time simulation results.
- Entering geometry information of the cross sections of the river.
- Use and analysis of the non-steady conditions and simulation.
- Realize a hydraulic model adding a bridge into the river system.
- Entering flow data.
- Use of Boundary Conditions.
- Developing a flooding model in 2D (two-dimension) using the most recent capability of Hec-Ras.
- Analysis of Satellite data information.
- Use of the Ras Mapper application for the visualization of the 2D simulation results.
- Analysis of the flow conditions.
