Steady Flow

Performing Steady Flow Analysis in HEC RAS
This post includes the procedure of calculating steady flow water surface profile.
This chapter is divided into two parts.The first part discusses how to enter steady fow data and boundary conditions.The second part discusses how to develop a plan and perform the calculations.

  1. Entering and Editing Steady Flow Data
  2. Performing Steady Flow Calculations
Entering and Editing Steady Flow Data
Once all of the geometric data are entered,the modeler can then enter any steady flow data that are required.To bring up the steady flow data editor,select Steady Flow Data from Edit menu on the HEC-RAS main window.The steady flow data editor should appear.

Steady Flow Data
The user is required to enter the following information: the number of profiles to be calculated;the peak flow data(at least one flow for every river reach and every profile); and any required boundary conditions.
