This output constitutes the upgraded version of the Solutions model adapted to territorial needs for transnational modelling of Hazardous Substances emissions in the Danube River Basin. The model was implemented within the Danube Hazard m3c project and is denoted as Danube Hazardous Substances Model (DHSM). The DHSM has been set up on the basis of the generic Delft3D open-source modelling framework, the central version of which is maintained by Deltares. The use of this framework is supported by a dedicated portal to download source code and manuals, to exchange experiences and to ask questions. This output consists of a file package and an annex. The file package contains four folders:

DHSM: the generic software plus all input files that together form the implementation of DHSM to the DRB. Scenarios: alternative sets of input data for the P25, best estimate (P50) and P75 emission estimates, and for the scenarios S01-S07. Supportive: some supportive files for presentation of the results. Documentation:

The general principles and operation of the DELWAQ framework used for the DHSM are documented in a User Manual  The input file format is documented in a separate manual The mass balances output is documented in a separate manual, included in the package. The accompanying annex "Danube River Basin Scale Assessment Report" provides a full account of the model approach and implementation.
