Simulation wizard: seepage and evaporation

[leendertvanwolfswinkel]

The API supports the inclusion of hydrological processes that add or remove water to the surface water domain, such as evaporation and seepage; in the API this is called surface sources and sinks. This this functionality is not yet available in the simulation wizard.

The endpoints are very similar to the rain endpoints:

/v3/simulations/{simulation_pk}/events/sources-sinks/constant/
/v3/simulations/{simulation_pk}/events/sources-sinks/rasters/lizard/
/v3/simulations/{simulation_pk}/events/sources-sinks/rasters/netcdf/
/v3/simulations/{simulation_pk}/events/sources-sinks/timeseries/
/v3/simulations/{simulation_pk}/events/sources-sinks/timeseries/netcdf/

I think we can more or less copy the functionality we have for precipitation, and add it to the simulation wizard as "Seepage and evaporation". The "types of precipitation" would change a little bit when applied to seepage & evaporation:

• Constant: sources-sinks/constant/

• From CSV: sources-sinks/timeseries/

• From NetCDF: sources-sinks/rasters/netcdf/ and sources-sinks/timeseries/netcdf/

• From Lizard: sources-sinks/rasters/lizard/

• "Design" and "Radar - NL Only" are not relevant for seepage & evaporation

• Add the following text at the top of the Seepage and evaporation page:

"Processes like seepage and evaporation are grouped in the more generic functionality Surface sources and sinks. This adds and/or extracts water from the 2D surface domain. These source and sink terms can represent any hydrological process, seepage and evaporation being the most common use cases."

• Add a "multiplier" option
