La diffusion du contrôle à la source des eaux pluviales urbaines : confrontation des pratiques à la rationalité hydrologique

Abstract : Urban stormwater management is facing a major evolution since 1960: from a strategy based on the complete and fast conveyance of stormwater outside of the urban area, to a strategy based on source control (SC). Recently, SC is becoming a common practice, in connection with the increasing diffusion of flow regulations. These regulations prescribe, for all new urban development, to build facilities (Best Management Practices, BMP) to reduce the flow-rate or the volume of stormwater entering the sewer system. A wide application of flow regulations will determine the future hydrological behaviour of many urban catchments. The choice of a regulation is a complex task for local authorities, involving several logics, whose global coherence can be discussed. This thesis analyses SC policies and regulations and discusses them in terms of their long-term hydrological effects. Two complementary approaches are developed. The first is based on the analysis of the evolution of SC policies in six French authorities, and it aims to define and discuss the logics applied. The second consists in the hydrological modelling of the consequences of SC regulations on the behaviour of two experimental catchments. This hydrological analysis allows (i) to evaluate the pertinence of actual SC policies and (ii) to discuss which tools urban hydrology can provide to support the development of coherent SC policies, according to the hydrological functioning of urban catchments
