Résumé
Some control measures of urban runoff are presented. The behaviour of the hydrological basin, with elliptic form, is studied in face of ground alteration and increased urban areas. By this way, it is shown how the flow created by the waterproofing of the soil, that exceeds the existent drainage capacity, can be stored in retention basin, solving flood situations. At the same time it can be taken advantage of the retained water for other purposes, especially during dry seasons. The types of retention basin and their potentialities are described here. And the existent situations are calculated demonstrating the conclusions obtained in this thesis.

Mots clés : runoff ; flow ; volume ; hydrological basin ; retention basin
