Hi,

You can use res11read.exe tool (from Mike suite) to do that. Copy-paste the code from below in an empty text file, modify the path to the Mike installation folder (where the res11read.exe is located) and the name of you result file, than save it with extension .bat in the folder where you have the *.res11 file.
------------------------------------------------------------------------
set PATH=%PATH%;C:\Program Files (x86)\DHI\2017\bin\x64

set res11FilePath="%CD%\RiverX Result File.res11"
set outputFilePath="%CD%\RiverX (XY-Nodes).txt"

res11read.exe  -xy %res11FilePath% %outputFilePath%

pause
------------------------------------------------------------------------

After double-click on it, a text file with geographical coordinates (X and Y) for all H and Q calculation points (grid nodes) in the model will be generated. Additionally information are also exported for each grid calculation point: river name, chainage, type of calculation point, bottom level, left bank level, right bank level, XY for left and right extreme end section and XY for marker 1 and 3 (see the attachment).

Kind regards,
Aurelian

Hello,

Yes, you can modify the chainage of cross sections: right click on the chainage of the CS from the tree view from left side -> Click on Rename... -> In the new window , under the section New name, modify the chainage by removeing the decimals. Please see the attached image.

Hello,

I think that the question is a bit broad. It would be very helpful if you can give more details about what do you want to do.

If you want to introduce human control of some hydrotechnical structures which may mitigate the flood, you can use the Control Structure sections (Network file) in Mike 11 (you need license for Structure Operation module to use this option).

Kind regards,

Dear Luca,

You can solve the problem in two steps. First, write the time series (and/or other data) from res11 file to an ASCII file, by using res11read.exe. Second, read the ASCII file with Matlab specific functions.

Hi,

In the boundary file, you have to define boundary conditions for each tributary. The definition of the items must include [b]Point Source[/b] and [b]Inflow[/b] as attributes. Please, see the attachment.

Dear sishodia,

My suggestion is to create a parallel branch with a few cross-sections on it, calculated so as to comply a specific H-V curve, if necessary. Anyway, you must also create a link channel which will transfer the water to the main branch when the specified threshould level is reached.

Please find attached two print screens with some details of a link channel where you cat set the threshould mentioned above.

Kind regards,
Aurelian

Dear Vitor Pessoa,

I don't know why the "Boundaries" menu is not present or available for your setup. It may be caused by your configuration. What modules have you checked ?

I recommend you to make the next test. You can open the example located at "...\Examples\MIKE_HYDRO\River\Demo\Cali.mhydro" and see if the menu named "Boundaries" is there. If you can find it on the menu bar it means that the problem is in your configuration. You can search for similarities and differences between your model setup and the one from examples. This could help you to find a solution.

Please find enclosed an image of a Mike Hydro setup which contains the menu mentioned above.

Best regards,
Aurelian

Dear Alison,

If you faced the Error No. 7 : "In river: SomeRiver, with Topo - ID : SomeTopoID, from  ... meter to ... meter no cross sections exist in the database ...", than the problem is that Branch Name of some of your rivers from nwk11 file doesn't match with the River Name field in xns11 file.

Please see the attachment where I illustrate a setup which generates the above error.

Kind regards,
Aurelian

Dear Humayun Malik,

I think that the problem is related to location of your structures. It's important to have the same location for dam (usually, represented at least by a weir structure) and for dambreak stucture. Also, if you want to set the failure mode by providing time series for the breach level, width and slope, you have to have, in addition of river name and chainage, the same value at the filed "ID" in Dambreak Str. (nwk11 file) and at the specific boundary item at the field Gate ID (bnd11 file).

I attached 3 files in order to be easier for you to understand what I mean. The example I gave you is a working one from my past work.

Kind regards,
Aurelian

Hi Eswar,

I think that what are you trying to do is quite unusual. Why not considering Branch2 as Main channel ? Think about the junction of two streams of water. How human culture conceptualizes the stream which is downstream that junction ? Is that a completely new river with a new name or is it considered as the continuation of one of the streams upstream that point?

From a technical point of view, a Mike 11 branch can end up with an open boundary condition or with a connection to another branch, even if it's a regular branch or a link channel. If you try to connect the ending point of a branch with two new branches, Mike will become confused which one to choose to connect with, since it can't split the water in two in this way.

The solution is two consider either Branch1 or Branch2 as the normal continuation of the Main channel (use connection tool for that) and the second branch can be connected via a Link Channel. This connection can be done just a few tens of meters upstream the end point of the Main channel (see the files attached*).

Note.
The "Diversions" option is available to do in the manner you tried only for routing channels, not on branches where the fully dynamic equations are applied (and I assume this is your case). For more information about this option, please consult the Help documentation (Mike 11-> River Network Editor -> Tabular View: Routing -> Diversions)

*After download the attachments, change the extension of Net1.txt to Net1.nwk11 in order to view the setup.
