Figure 3-20: Display at the map the location of the time series. You might want to disable the Discharge Location, so you can only see the places where time series have been written. The three channel flows presented above correspond to the three location presented in the map. Figure 3-21: Time Series Location in the map. Before continuing with the next example, just remove the layer called channel flow from the list of layers. You can do this by selecting the layer and choose remove remove from the context menu.

25 4 Example 2 Rainfall & Infiltration The next example is based on the same watershed as the previous example, but in this configuration, the porous media module is activated and real meteorological conditions are provided. Rainfall should infiltrate into soil. Go to Explorer and select the simulation Watershed with soil. Figure 4-1: Example 2 Watershed with soil. Run the example in the same way you did for example 1: 1. Select Run Now from the Main Menu 2. Wait for the simulation to finish 3. Check the status of the model execution. As mentioned previously, this example contains soil, so precipitation infiltrates into the soil. We can analyze model result time series to verify model behavior. Time series with extension *.srb contain general basin data, time series with extension *.srp contain soil property data. A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 20

26 To see the amount of rain, select the Watershed with Soil simulation and double click the file 25_57_9.srb file in the list of time series results. Figure 4-2: Loading time series with rain information On the next window, select the Precipitation Rate series and hit OK to show it in form of a graph. A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 21

27 Figure 4-3: Selecting the Precipitation Rate series The graph window shows that there are two small rain events. Figure 4-4: Two small rain events Go back to the explorer and double click again on the same file (25_57_9.srb). This time, select the infiltration rate and select Add to exiting window. A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 22

28 Figure 4-5: Loading infiltration rate into the same graph window With this configuration, the graph shows a comparison between the precipitation rate vs. infiltration rate. Figure 4-6: Comparing precipitation rate and infiltration rate A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 2 3

We expect that the water which infiltrates increases the soil water content (soil moisture). We can verify this by loading the time series of the porous media properties.

29 We expect that the water which infiltrates increases the soil water content (soil moisture). We can verify this by loading the time series of the porous media properties. Just double click on the file 25_57_9.srp and then select the series relative water content. Figure 4-7: Loading the relative water content The resulting graph shows that the relative water content increases during the rain events. A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 24

The time series which has been analysed is located just over a channel network (it s the middle one of Figure 3-20: Display at the map the location of the time series. ).

30 Figure 4-8: Increase of soil water content during rain events. The water which does not infiltrate will pond on the surface of the soil. It can either infiltrate over time, runoff as overland flow or drop into a channel. The time series which has been analysed is located just over a channel network (it s the middle one of Figure 3-20: Display at the map the location of the time series. ). So water from this cell will result in channel flow. By double clicking the channel flow time series (channel flow.srn), and selecting one of the series, you can see channel flow generated by this specific simulation. Figure 4-9: Channel flow generated by the two rain events A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 25

To see all this features in form of map, go back to the explorer, select the simulation Watershed with Soil and double click on the Drainage Network.hdf5 file.

31 To see all this features in form of map, go back to the explorer, select the simulation Watershed with Soil and double click on the Drainage Network.hdf5 file. Load the channel flow layer (see previous example). Using the timer, you can step through the results and see the channel flow generated from the two small rain events. Figure 4-10: Channel flow generated by the two rain events (maps) Before continuing with the next example, just remove the layers called channel flow from the list of layers. You can do this by selecting the layer and choose remove remove from the context menu. Also close all opened graph windows. A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 26

5 Example 3 Rainfall & Infiltration & Surface Runoff The next example is a continuous simulation from the previous example, but this time a much stronger rain event will occur.

32 5 Example 3 Rainfall & Infiltration & Surface Runoff The next example is a continuous simulation from the previous example, but this time a much stronger rain event will occur. Go to Explorer and select the simulation Heavy Rain. Figure 5-1: Example 3 Heavy Rain. Run the example in the same way you did for example 1 and 2: 1. Select Run Now from the Main Menu 2. Wait for the simulation to finish 3. Check the status of the model execution. A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 27

33 As mentioned previously, this example contains soil, so precipitation infiltrates into the soil. The precipitation intensity is set so high that it exceeds infiltration capacity of the soil, so not all water will infiltrate. Excess water will result in surface runoff. After the simulation finished, analyse the time series like in example 2 Next figure shows the comparision between precipitation rate and infiltration rate. As you see, precipitation exceeds largely infiltration capacity. Figure 5-2: Precipitation vs. Infiltration Rate From the HDF results load the channel flow (Drainage Network 6.hdf5), as described in the previous examples. To load the overland flow (surface runoff), select (not double click) the file RunOff_6.hdf5 in the list of HDF result files. Click on the small icon with arrows next to the list, as shown in the next figure. A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 28

34 In the next window, just hit OK. Figure 5-3: Loading surface runoff Figure 5-4: Loading surface runoff (second step) A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 29

Switch to the map window and select the layer called flow [0] ( ). Double click it to configure the layer. Configure the layer as shown in the next figure. Then close to go back to the map.

35 Switch to the map window and select the layer called flow [0] ( ). Double click it to configure the layer. Configure the layer as shown in the next figure. Then close to go back to the map. Figure 5-5: Configuring the overland flow layer By using the timer and the zoom functions, you can check the overland flow pattern, as shown in the next figure. A c t i o n M o d u l e r s - w w w. a c t i o n m o d u l e r s. c o m 30

36 Figure 5-6: Overland flow When you step through the results, you will first see the overland flow, as response to the heavy rain event. Next you will see some arrows which appear along the channels. This always occur when the channel capacity is exceeded and the channel gets adjacent areas to the channel get flooded.
