Bulgaria Diffuse Pollution model setups in Mobius2

These are model setups for models made with the Mobius2 model framework. See https://nivanorge.github.io/Mobius2/ for how to install and use the framework. The 'models' folder is a snapshot of the models folder of the Mobius2 repository in case the models in the main repository change to be incompatible with the setups here. The setups are further described in the NIVA (Norwegian Institute for Water Research) report "CAPACITY BUILDING FOR DEVELOPING AND IMPLEMENTING A METHODOLOGY TO ASSESS PRESSURE AND IMPACT OF POLLUTION SOURCES ON BLACK SEA MARINE WATERS Results from the pilot study areas: the Yantra catchment and the Beloslav Lake–Varna Lake–Varna Bay System" (to appear) They were developed as a part of the project DIP (Diffuse Inland Pollution to Surface Waters), funded by the Environment protection and climate change Programme co-funded by the EEA FM (2014-2021), bilateral fund. The data in the included model setups are for use with the included models only. If you want to use the data for another purpose, you should obtain the data from their original source(s). Water quality observations originally come from the Danube River Basin Directorate (Yantra) and the Black Sea Basin Directorate (Varna). River discharge data is from the Bulgarian National Institute of Meteorology and Hydrology. Nitrogen deposition data is from the EMEP gridded dataset. Meteorological data is from ERA5-land (Copernicus Climate Data Store (CDS)) and from local meteorogical stations.
