It has a length of approximately 20 km and is located in North-Rhine Westfalia, passing the cities of Solingen, Hilden, and finally southern parts of Düsseldorf, where the Itter flows into the Rhine river. Three municipal sewage treatment plants, serving in 1996 a total of 182,137 population equivalents, are discharging into the Itter. The incorporation was financed by the Henkel KGaA and carried out by Carsten Schulze. More information about this catchment can be found at http://www.usf.uni-osnabrueck.de/~cschulze/itter/index.en.htm Top of Page Unter-Main Catchment The Unter-Main is a very small application available on the GREAT-ER 1.0x CD, illustrating the application of GREAT-ER for industrial point discharges. Top of Page Main Catchment This application of GREAT-ER to the Main river (Germany) was sponsored by Clariant GmbH and IKW, and was developed by Osnabrueck University. The report "Application of GREAT-ER in the catchment of the river Main" (Dec. 2001) by Joerg Klasmeier and Michael Matthies is attached below. Simulated chemicals are LAS, HHCB and Diclofenac. ETGRTD_JK2.pdf (355 kb) Top of Page Roer Catchment This catchment was developed by Carsten Schulze at Osnabrueck University as part of his PhD thesis, and is available on the GREAT-ER 1.03 - 1.05 CD, GREAT-ER desktop and -web. The project was sponsored by Henkel KGaA. The Rur catchment area has an area of approx. 2,500 square km. It discharges wastewater for about 1 million inhabitants, which is increased by industrial discharges contributing wastewater for an additional equivalent of 900,000 inhabitants. The largest city is Aachen/Aix-La-Chapelle. The upper courses of the Rur and its tributaries are comparable to low mountain rivers, whereas the lower courses are situated in a flat region where significant anthropogenic impacts occur. The border between these two parts is marked by large water reservoirs, e.g. the `Rurtalsperre' which is one of the largest in Germany. These are partly used as drinking water reservoirs.

Top of Page Rhine-NRWF Catchment This subcatchment of the Rhine is limited to the borders of Northrhine-Westfalia (NRWF). This area reaches from km 640 at Bad Honnef to km 853 at Kleve-Bimmen, including the tributary catchments of Sieg, Wupper, Ruhr, Emscher, Lippe and Erft. This project (2005) was developed by Osnabrueck University and was sponsored by the UBA. This catchment is available on a separate data-CD (via the order form), together with the Elbe. For use with GREAT-ER desktop only. Top of Page Elbe Catchment The catchment is limited to the south by the Czechian border, to the north by the barrage of Geesthacht. The area modelled covers about 90.000 km2 and includes the subcatchments of Schwarze Elster, Mulde, Saale and Havel. This project (2005) was developed at Osnabrueck University and is sponsored by the UBA. This catchment is available on a separate data-CD (via the order form), together with the Rhine-NRWF. For use with GREAT-ER desktop only. It is a very large catchment that requires a modern PC and preferably > 512 MB RAM memory.
