Thank you for your answer.

Yes I know which presentation you are referring to. The presenter mentioned that the clogging occurred when a given wetted area was reached. Then I assume the wetted area is limited to the area with clogging. I was however not able to get the answer to how he effectively implemented a constraint to the wetted area in the "after clogging part" of the BASEMENT modelisation, i.e. how one can limit the wetted area to a given value at a given place in the model.

For some projects it would be important to get the maximum values on the Stringdefs for the "FLOOD" output, e.g. a FloodVar in results.h5/RESULTS/NodeStrg/FloodVar. I know that this is probably not straight forward to implement, but it would be a really useful output.

Hope this feedback helps to further improve the output.

Best regards

I realized that some times it would be good to have the maximum flow velocity vector (vx, vy) of the corresponding maximum absolute flow velocity in the "FLOOD" output (written in results.5/RESULTS/CellsAll/FloodVar) to indicate the flow direction during the peak of a flood event. Note that this is not the same as the separate maximum values of vx and vy.

Hope this feedback helps to further improve the output.

Best regards
Lukas

Thanks for raising those issues. If you send us the modified code, we will gladly evaluate to include it the improvements in the official version and will have a look at issues 1. and 2.

Best,
Matthias

Thanks for reaching out.

It looks like the STANDARD boundaries in_flow1 and in_flow2 are defined inside the mesh domain, please know that STANDARD type boundary only applies at domain boundary and make sure the geometry setting is correct.

I'd like to understand the meaning of thid statement about "capacity transport" in GUI help: [...]
It is also possible to specify a time series with the inflowing sediment volume [m3/s], which then is distributed on the grain fractions according to the calculated transport capacities [...].
Time series stands for "sedimentograph"? in such a case if I insert "file" item, a warning inform me that it will not be used!
Please, someone could explain me how can I add sediment from upward watershed basin into my domain other that "sediment discharge" (giving big problems)?
Thanks.

I would like to ask whether, during mesh generation from a DTM, it is possible to introduce points or lines with known elevations that override the original DTM values locally.

Thank you very much for your time and support.

Kind regards,

However, while running some tests and looking at the influence of the initial conditions, I noticed that if I increase the slope, at the same flow rate, the issue of high inlet velocities is progressively reduced.
That said, this solution is not very realistic in practice. Do you have any other ideas or suggestions?

However, when I try to run the flood hydrograph, everything works correctly up to a certain point (around 16,800 s out of a total of 60,000 s), where there is a sudden increase in the inflow velocities (from 4 m/s to 8–10 m/s), and I don’t understand why. Could this be a problem related to the morphology of the inlet section?

Thank you for your help.

Thank you for Basement 4.2.0.

In previous versions of Basement, there was a description of the input structure for the command file in "doc_BASEMENT.html". Is there an updated version of this file for Basement 4.2.0 ?

Thank you for your answer

I´would like to restart one of my BASEMD modells that is made in BASEMENT 4.1. My initial parameters are

initial I set "file" = results.h5       
"HYDRAULICS": {
          "INITIAL": {
            "type": "continue",
            "file": ".../result.h5"
            "restart_solution_time": -1
          },

Running this creates the following error:

WARNING -> Determining the existing solution times failed: Accessing the HDF5 group
   '/RESULTS/CellsAll/Depth' failed.

WARNING -> Parse error when trying to read the HDF5 restart file: Accessing the HDF5
   group 'RESULTS/CellsAll/Depth' failed..

#=========================
If i change to:

"HYDRAULICS": {
          "INITIAL": {
            "type": "continue",
            "file": ".../restart.h5"
            "restart_solution_time": -1
          },

I get this error:
WARNING -> Not all needed data could be found in restart file.

ERROR -> ERROR opening HDF5 file './\LHSG_restart.h5', error: Opening the HDF5
   file at './\LHSG_restart.h5' failed.
When I look at the result.h5 in hdf5 viewer it seems empty but I do get

#========================

When I look at the results.h5 file inside HDFviewer. di dictionary structure is like this:
results.h5
  .config
  Domain
    LHSG
      .config
      CellsAll
      NodesAll
      RESULTS
        CellsAll
          Depth
             0   - includes data from timestep 0.0 (no data)
             1   - includes data from timestep 4500.000....
          VelocityX
             0   - includes data from timestep 0.0 (no data)
             1   - includes data from timestep 4500.000....   
          VelocityY
             0   - includes data from timestep 0.0 (no data)
             1   - includes data from timestep 4500.000....

The restart file contains the this data as well.

Any ideas or suggestions on what I should try to do to get it running??
