summary |
Reservoir road surfaces can be seen as equipment of the future, in that they have two functions in the same structure (circulation and hydraulic functions). They can thus be laid without immobilising land, which is very expensive and prized in urban areas. Furthermore, they enable the limitation of the flow or volumes of running water, and thus help control rainwater, resulting in better flood risk management. The questions asked by drainage designers are how can we design these structures in the best way? How are they going to work for different types of rain (rain from storms, prolonged winter rain ....)? As for the public administrators, they wonder how a series of areas equipped with this type of technique (total flow management) would work. By solving this latter problem, we could really arouse interest in flood risk management. Given the diversity of structures possible for reservoir road surfaces (regulated, non-regulated, draining surface, dispersion surface...), we suggest comparing design and simulation methods, taking into account the measurement and total flow management problems mentioned above. So as to validate these comparisons and to give some directions concerning the use of one or the other methods, we use flow-metre measures on two different sites in Lyons. One of these sites is a car- park on a tertiary activity zone on the La Doua campus in Villeurbanne, the other a refuse dump in the Greater Lyons area in the town of Craponne. They are both interesting as they have different features. The first is non-regulated downstream and is used on a car-park for light motor-vehicles. The other is regulated and the traffic on it is made up of lorries. These sites will be described in this article. |
