MoRE (Modeling of Regionalized Emissions)
The Directive 2008/105/EC (on environmental quality standards) of the European Parliament and the Commission ask all Member States an inventory of emissions of priority substances for all river basin districts (EP, 2008). This task requires appropriate data and approaches for the description of the current state of surface water bodies and the evaluation of appropriate measures for the reduction of emissions into the surface water bodies to achieve a good ecological state of surface water bodies and to meet the quality standards set.
Based on these requirements the proven MONERIS concept that was developed for modelling of nutrient emissions into the water bodies (Behrendt et al., 2000), was adapted for the pollutant emissions and implemented in an open source environment as river basin management system MoRE (Modelling of Regionalized Emissions).
The MoRE system comprises approaches for the emission pathways: municipal wastewater treatment plants, industrial direct dischargers and emissions of historic mining for pathways related to point sources and the following emission pathways related to diffuse sources: sewer systems, surface runoff, erosion, groundwater, tile drainage, direct atmospheric deposition onto water surfaces and inland navigation. In addition to the modelling of emissions into the water bodies an estimation of the river load is carried out to verify the model results. The above mentioned modelling approaches and sources of input data are described in detail in Fuchs et al. (2010).
The MoRE system is based on an open source PostgreSQL/SQLite database, a generic calculation engine and two different graphical user interfaces (GUI): the MoRE Developer GUI and the MoRE Visualizer GUI (Figure 1). The GUIs have been developed for user interaction with the PostgreSQL database. The PostgreSQL database content can be easily read, changed and extended via the MoRE Developer GUI. Also, modelling can be launched via a calculation engine which is incorporated in the Developer GUI with a dynamic linkage to the PostgreSQL database. Modelling results can be output as table in MoRE Developer or visualized as map or chart via a GIS-browser (MoRE Visualizer). Users can work with the MoRE river basins management system either on a multi-user basis using the PostgreSQL database via internet or via a single user application for PC.
