Katariina,

as dummy reach (or Storage Area) I mean a fictitious reach that doesn’t exist in the system you want schemayize.

You can create a normal reach, define it with simply rectangular cross sections, define flow upstream and water level downstream, than link the output of your pumping station to this reach.

In this way your pumping station works and it doesn’t matter what happen in the dummy reach.

Katariina,

if you are not interested on the outlet you can create a dummy reach or better dummy SA with very large volume.

You have to get this result from DSS.

Open the DSS with DSSView and select:

PART A: “the Reach you want”
PART C: LOCATION-ELEV
PART E: MAX STAGE
PART F: “the run you want”
click the Tabulate icon (top left)
Here you have the max stage for each RS

PART A: “the Reach you want”
PART C: LOCATION-FLOW
PART E: MAX FLOW
PART F: “the run you want”
click the Tabulate icon (top left)
Here you have the max flow for each RS

PART A: “the Reach you want”
PART C: LOCATION-TIME
PART E: MAX STAGE
PART F: “the run you want”
click the Tabulate icon (top left)
Here you have the number of hours after the simulation start when the max stage happen

PART A: “the Reach you want”
PART C: LOCATION-TIME
PART E: MAX FLOW
PART F: “the run you want”
click the Tabulate icon (top left)
Here you have the number of hours after the simulation start when the max flow happen

I’m not completely agree that delete the area occupied by buildings is the best solution.

If the inside of the buildings can be flooded using the high n number (eg. 10) in the buildings area could well represent this phenomenon. The hydrodinamic (velocity) around the buildings will not be so different in the 2 approaches.

To define high n value in the buildings area you need to define the mesh elements exactly around the specific areas.

At the end, if you already have the DTM with the buildings it will be easier to use directly the DTM, if you have to modify the DTM to include the buildings, probably define the higher n value could be better.

Adnan,

I’m not completely sure but junction has only 3 reaches. To solve your problem you can create a dummy reach between two junctions. In the US juction you will have the 2 inflow plus dummy reach, in the DS junction you will have the dummy reach and the 2 outflow. To define the dummy reach you can use 2 XS very close.

I had this problem some years ago.

I think, but I’m not sure, I solved the issue defining the deck from the first point of the US XS.
You can define the elevation of high cord at the same level of XS points.

I guess the flow under the bridge is only in a width as the XS next to the Bridge DS XS depicts.
In this case I suggest to define the Bridge DS XS with this width and not for the whole bridge.

Paolo

[PaoloP]

No, you can’t.

If you are not interested on tributary and the flow from the tributary is not influnced by level in main river, you can delete the tributary and add it as lateral inflow BC.

Thanks Chris, I googled and I found this:

to close (or open) an APP see:
http://www.taltech.com/support/entry/opening_and_closing_an_application_from_vba

but I discovered that closing RAS the APP doesn’t work for a second RUN (I guess it is linked with public declaration of HECRAS Controller)

For this reason I decided to close Excel at the end of the run, to do this see:
