The paper presents a part of the SDSS approach from the FLUMAGIS-project. In the prototype several case-studies are developed to test the planning and assessment tools. This comprises the representation of flowing waters and landscape ecological aspects as well as aspects of water and emission balances in the study area of the upper Ems catchment (3740 km\302\262) in the northwest of Germany. One focus of the project was the role of urban areas affecting the river system in different ways, e.g. as priority pollutants from urban areas and hydrological stress caused by storm water discharge. An overview of the applied and developed methods and functionalities in FLUMAGIS is given. Further more an extract of the urban relevant case studies is offered. This comprises an integrated evaluation of river sections, considering hydrological aspects as well as an emission balance of rainwater discharge. However, due to the high interdisciplinary approaches only a few aspects can be described within this paper.
