HEC-RAS may be used in HEC-RTS to simulate the behavior of channels in a watershed, given flow rates predicted with HEC-HMS. There are several reports available from HEC-RAS for the HEC-RAS model alternative, and for HEC-RAS model elements. From an HEC-RAS model alternative you have a series of reports, that provide you with results for key variables; distribution of flow (left and right overbank, main channel); steady flow results; unsteady flow results; rating curves; and, much more. There are two HEC-RAS model elements (cross sections, routing reach), you can review plots of cross sections; and, plots from routing reaches (profiles, XYZ).

Standard Table 1

The Standard Table 1 is the default summary table (Figure 1). This table gives you a summary of some the key output variables. To view the Standard Table 1:

Standard Table 2

The Standard Table 2 (Figure 2) is the second of the standard summary tables. This table provides information on the distribution of flow between the left overbank, main channel, and right overbank. This table also shows the friction losses, as well as contraction and expansion losses that occurred between each section. Energy losses displayed at a particular cross section are for the losses that occurred between that section and the next section downstream.

RAS Mapper Results

Within the HEC-RAS software application, when performing an unsteady flow analysis, RAS Mapper is a tool that you can use to be build various type of inundation maps (Depth(max), Velocity(max), WSE(max), D*V(max), Arrival Time). If the HEC-RAS model alternative in an HEC-RTS forecast run, includes running RAS Mapper, and an HEC-RTS forecast compute is successfully, then you will have inundation map(s) that you could view in the Map Window. To view RAS Mapper inundation maps:

  1. From the Modeling module, to view RAS Mapper inundation maps, make sure you have an active forecast and at least one forecast run selected (checkbox) for viewing results. From the Forecast Runs Detail section, select an HEC-RAS model alternative (Russian River Real-Time), from the Forecast tabs, click Reports.
  2. From the Reports section, there are three buttons – Depth (Max), D_V(Max), and Arrival Time (2ft hrs). These buttons are toggles, which will cause the RAS Mapper inundation maps to display in the Map Window (Figure 12). For example, in Figure 12, you have clicked Arrival Time (2ft hrs), which will cause the associated inundation map to display. If you click Arrival Time (2ft hrs) again, the inundation map will no longer display. For further details on the RAS Mapper tool, refer to the HEC-RAS User's Manual (Chapter 20).
