The RAS Mapper gives you the possibility to perform inundation mapping of water surface profile results directly from HEC-RAS. Graphs can be printed or copied to the clipboard.

The program gives you the possibility to create multiple projects, store the input data in flow files under separate categories (project, plan, geometry, steady flow, unsteady flow, and sediment data), create graphs which embed X-Y plots of the river system schematic, cross-sections, profiles, rating curves, hydrographs, and many other hydraulic variables, as well as generate a three-dimension plot of multiple cross-sections. There’s also support for a comprehensive help manual in case you want to find out more about the program’s capabilities, as well as tooltips.įrom the user interface you can activate the following functions: file management, data entry and editing operations, hydraulic analyses, tabulation and graphical displays of input and output data, and reports. The tool comes packed with a bunch of dedicated parameters, so you need to take some time and experiment with the built-in features. This one-dimension utility is able to model water flowing through systems of open channels and compute water surface profiles. Hydraulic engineers may take advantage of channel flow analysis and floodplain determination. It offers support for multiple analysis parameters, namely steady flow water surface profile computations, unsteady flow simulation, movable boundary sediment transport computations, and water quality.

When this file is imported to HEC-RAS, we can obtain velocity and depth results through hydraulic calculations. Finally, these results can be exported to ArcGIS to be processed and therefore obtain flood and risk maps.HEC-RAS is a professional Windows application whose purpose is to help engineers perform detailed water flow and sedimentary computations. This HEC-geoRAS file gathers geometric data of the study area including the riverbed, cross sections, water flow lines, etc.
Hec ras manual portugues series#
It consists of a series of procedures, tools and uses designed to process georeferenced data that allow preparing geometric data to import to HEC-RAS. HEC-geoRAS (Hydrological Engineering Centre – Geospatial River Analysis System) is an extension for ArcGIS developed by Hydrologic Engineering Centre of the United Army Corps of Engineering together with the Environmental System Research Institute (ESRI). It allows simulating flow in natural riverbeds or artificial channels to determine the water level being its main goal develop flood studies and determine floodable areas. HEC-RAS (Hydrological Engineering Centre – River Analysis System) is a one-dimensional hydraulic modelling program based on 4 types of analysis in rivers: This has made that, little by little, the majority of administrations have begun to demand the study of the impact that any type of intervention could mean over a riverbed´s dynamic using a sufficiently reliable hydraulic model, as for example HEC-RAS.
Hec ras manual portugues update#
It is a free software, commonly used, and in constant process of update thanks to continuous improvements. Among all of them, there is no doubt that HEC-RAS software stands out (developed by Hydrologic Engineering Centre of the US Army Corps of Engineers) being one of the reference programs in its area.

Nowadays, diverse softwares specific for hydraulic modelling simplify data entry and allow observing the results graphically, even exporting them in table format, making their interpretation easier. If, in addition, there are water works in the riverbed (bridges, canalisations…) or we wanted to know what would happen if they existed, the problem gets more complicated. It is not an easy task to answer these questions as we have to take into account several factors like the riverbed type, its slope or nature (type of material, presence of vegetation, etc.). When we study a segment of a specific river to see where the water would flow if reached a certain value, different questions arise such as what will be the height reached by the water profile? Will surrounding areas be flooded? To what extent?
