Chapter 3 Working With HEC-RAS - An Overview

The HEC-RAS main window has the following options on the menu bar.

File This option is used for file management. Options available under the
File menu include: New Project; Open Project; Save Project; Save Project As;
Rename Project: Delete Project; Import HEC-2 Data; Import HEC-RAS data;
and Exit. In addition, the four most recently opened projects will be listed at
the bottom of the File menu.

Edit This option is used for entering and editing data. Data is categorized
into four types: Geometric Data; Steady Flow Data; Unsteady Flow Data; and
Sediment Data.

Simulate This option is used to perfonn the hydraulic calculations. The
options under this menu item include: Steady Flow Analysis; Unsteady Flow
Analysis; Sediment Analysis; and Hydraulic Design Functions.

View This option contains a set of tools that provide for graphical and tabular
displays of the model output. The View menu item currently includes: Cross
Sections; Water Surface Profiles; Rating Curves; X- Y -Z Perspective Plots;
Cross Section Tables; Profile Tables; and Summary Err, Warn, Notes.

Options This menu item allows the user to change Program Setup options;
set Default Parameters; establish the Default Units System (English or
Metric); and Convert Project Units (English to Metric, or Metric to English).

Help This option allows the user to get on-line help, as well as display the
current version infonnation about HEC-RAS.

Steps in Developing a Hydraulic Model With HEC-RAS

There are five main steps in creating a hydraulic model with HEC-RAS:

. Starting a new project

. Entering geometric data

. Entering flow and/or sediment data

. Perfonning the hydraulic calculations

. Viewing and printing results
