<br />Chapter 3 Working With HEC-RAS - An Overview <br /> <br /> <br />Figure 3.6 Steady Flow Data window <br /> <br />Performing The Hydraulic Computations <br /> <br />Once all of the geometric data and flow data are entered, the modeler can <br />begin to perform the hydraulic calculations. As stated previously, there are <br />four types of calculations that can be performed: Steady Row Analysis; <br />Unsteady Row Analysis; Sediment Transport Analysis; and Hydraulic Design <br />Functions. The modeler can select any of the available hydraulic analyses <br />from the Simulate menu bar option on the HEC-RAS main window. An <br />example simulation window is shown in Figure 3.7, which is the Steady Row <br />Analysis window. <br /> <br />3,8 <br />
