Each Cross-Section should intersect the centerline both bank lines. The documentation for HEC-RAS consists of a Users Manual which describes how to use the interface.

While the GeoRAS extension is designed for users with limited geographic information systems GIS experience knowledge of GIS is advantageous. A two-dimensional Users Manual which describes how to use the two-dimensional and combined one- and two- dimensional modeling capabilities. A Hydraulic Reference Manual which describes the data required equations used solution techniques and modeling advice.

Check flow data Boundary condition. The next step is to go to the Geometric Data editor and import the GISCADD data into HEC-RAS. Run Model View Output 10.

They are always digitized from left to right looking downstream. Check flow data HEC-RAS MAIN WINDOW Flow data. Chapter 14 Using GIS Data With HEC-RAS 1.

The ApUtilites menu contains functions mainly for data management. A record can also contain a value or a set of values following the keyword ie after the colon. Add the Bridge Data 7.

This post will feature a steady flow example project and will list common HEC-RAS files that youll see for Unsteady flow Sediment Analysis Water Quality and Hydraulic Design projects. This example consists on a water channel that overflows. The Help menu is self-explanatory.

Referential parameters will be used. Notice the fourth folder called Applications Guide. Check geometric data Save geometry data.

This HEC-RAS geometry file contains physical. To analyze stream flow HEC-RAS represents a stream channel and floodplain as a series of cross-sections along the channel. To create our geometric model of Waller Creek for example we need to import the geometry file that you just downloaded.

3 The RAS Geometry menu contains functions for pre-processing of GIS data for input to HEC-RAS. In Excel well use the Visual Basic editor to write. Add the Culvert Data 6-bridge.

Navigate to the above folder location and open. For this example normal depth with So001 is set for downstream BC. Start a New HEC-RAS Project 2.

Although these examples all use the number 01 in the extension RAS can have multiple instances of each of these files for a given project except the prj-only one of those. The RAS Mapping menu contains functions for post-processing of HEC-RAS results to produce flood inundation map. For this example a prj has been provided in the same directory as the tutorial drawing.

From the Ras Mapper form click on Tools Set Projection for Project. This is accomplished from the File menu of the main HEC-RAS window. 1D HEC-RAS Model Development using RAS-Mapper.

Records and Keywords The HEC-RAS geometric data import file is composed of records which in turn are composed of keywords and values. A BSTEM Technical Reference and. You will learn more about the functions associated with these menus and buttons in.

Here we will present the steps and needed considerations to model riverchannel flow in HEC-RAS. Add the Road Deck 6-culvert. Set Up the River Reach 3.

Save Flow data. GISCADD data are imported by selecting Import Geomtric Data and then GIS Format from the. They must span over the entire flood extent to be modeled.

Add Ineffective Flow Areas 8. Once HECRAS 50 is installed change the system units in Options Unit System US customary SI. All records must contain one keyword and all keywords end with a colon.

HEC-GeoRAS is a GIS extension that provides the user with a set of procedures tools and utilities for the preparation of GIS data for import into HEC-RAS and generation of GIS data from RAS output. For example mine is CHEC-RAS ExamplesApplications GuideChapter 1 Critical CreekCRITCREKprj. They are digitized perpendicular to the direction of flow.

You will be using the filename and path later in the code. After starting HEC-RAS select Geometric Data from under the Edit pulldown menu to open the Geometric data editor which has a CAD screen and various options. As you can see in the figure below the example projects are organized into 5 folders after you download them and unzip them to your computer.

Once you confirmed you can open up the Critical Creek project in HEC-RAS and youve spent some time getting familiar with it go ahead and close HEC-RAS. These are all of the HEC-RAS projects. From the File pulldown menu on the Geometric data editor run Import Geometric Data - GIS Format command and select the GEO file just created.

As an example a modified Bald Eagleproject data from HEC-RAS Unsteady Examplesare used. CCSS Training DataCivil Site DesignHEC-RAS 10. Enter Cross-Section Data 5.

The archive contains also QGIS project file with all the data and projection defined NAD 1983 StatePlane Pennsylvania North FIPS 3701 Feet. You also have the option to download a larger install package that contains the Example Data Sets. In HEC-RAS main project window use FileImport HEC-RAS Data and choose the file Wallerg01.
