New criteria for stormwater discharges into urban streams

摘要: The Germany state of the art for designing stormwater discharges and combined sewer retention tanks is emission oriented. This approach does not adequately reflect needs urban brooks. Literature on topic shows need further research investigations. Firstly, a detailed study used to define hydraulic impact overflows an stream. paper attempts relate in form shear stress with substrate movement. correlation between extent impacts ecomorphological properties considered be significant parameter evaluation runoff. Finally new assessing into brooks presented. divided pollutant components takes consideration.
