L'augmentation des surfaces imperméables et les modifications des chemins d'écoulement de l'eau par les réseaux d'assainissement unitaires et pluviaux ont un impact sur l'hydrologie des bassins versants. Les bassins périurbains, qui s'urbanisent rapidement, y sont particulièrement sensibles. Les outils de modélisation hydrologique spatialisés, simu...
Managing urban storm water is challenging under the best of situations, and due to projected increases in intensity of rainfall events, is exacerbated by climate change. Institutional and individual aspects of urban storm water management and the implications for low-impact development (LID) are presented. The paper frames storm water as a public g...

Die Klaeranlage Markranstaedt war eine mechanische Behandlungsanlage, bestehend aus Grobrechen, Sandfang und Emscherbrunnen. Die Einleitung des ausschliesslich mechanisch gereinigten Abwassers erfolgte in den empfindlichen Vorfluter 'Roter Graben', der an dieser Stelle keine eigene Wasserfuehrung aufweist. Um die Anlage an die heute ueblichen Reini...

The potential for long-range transport and persistence were proposed as criteria for the evaluation and regulation of plant protection products and industrial chemicals. The inclusion of these criteria was proposed in order to achieve a sustainable and precautionary use of chemicals of environmental relevance. The 'overall persistence' and the 'cha...
