VI. Running a Simple Rainfall-Runoff Simulation

For this exercise we will continue working on the Burns Creek basin. You are expected to have a fully loaded database at this point. If you had troubles downloading data and puting together your database, you can download this zip file, which contains the database developed in the previous sections of this tutorial (click here to download).

  1. Open the Rainfall-Runoff Model Tab
    • Right-Clicking on the outlet (defined in the previous tutorial) will launch a menu of options.

    • Click on the “Rainfall-Runoff” button. It launches the “Rainfall-Runoff” module.

    • Select the “Sample Simulations” tab.

    • Change the values for Runoff intensity and Runoff Duration, and press the “Constant Velocity Simulation” button.
    • A window will pop-up with a request for the directory where the output file will be wirtten.
  2. Data file features
    • Two CSV files are created at the location you chose. They both have the same name of the DEM plus an extension: “Routing_CV.csv” and “wfs.csv”
    • The “Routing_CV.csv” file: This file can be open with Excel or any other spreadsheet. The file looks something like the figure below.

      There is a column of information for the end link of every complete stream in the network (note: order 1 streams are not included in the file).The rows of information include Horton order, upstream area, outlet ID, and discharge for different moments of time. (TIP: you can sort the information by selecting all the rows and using the command “Data -> Sort”, notice that you need to specify that the information is in rows and not in columns).
