how to apply multiple rain gages

[jbensabat]

hello
I am running a case with NUFLOOD over a basin of ~50 Km2 in which the rainfall (intensity and geographic distribution is not uniform. One way to do so is to use multiple rain stations. Is there a way to do that ?

Do you mean that you want to introduce water to the system via independent volumetric point sources? If so, I've added another example, point_source/flat within the Nuflood examples repository. If you read the data documentation and the JSON file of this scenario, this scenario adds two point sources at different locations within the domain, where the volumetric flow out of each point source is defined via a CSV file. This is a very basic example, but hopefully it is understandable. If this isn't what you're looking for, please let me know since I may have misunderstood your question.

Hello and thanks for your reply
I did not explain myself clearly.
I have a case in which the rainfall is distributed in an heterogenous way both in terms of cumulative rainfall and distribution in time. For this I need to have the possibility to load multiple raingages
I modified the ISources class in the common library so it can accomodate more then one timeseries (actually a map of timeseries) and a additional grid file in which each cell is associated with a raingage (or timeseries, identified by an id).
now I am trying to figure out how to modify the code so it can calculate the rainfall on cell basis with the new data.
From what I have seen in the code, this option does not seem to be implemented.

Okay, I think I understand now. You're correct that such a feature is not implemented. It sounds like you may be on the right track with your implementation, though.
