Les modèles physiques en hydraulique urbaine
Physical models in urban hydraulics
SAFEGE Ingénieurs Conseils, Hydraulic Models Limited
Physical models are a means of in-depth investigation. In Urban Hydraulics they can be used for most types of infrastructure, including pumping stations, treatment facilities and the more complex sewer system components. Models can serve not only to check and adjust the design of new works prior to their construction but also to determine the exact causes of impaired operation of existing facilities and propose solutions for their rehabilitation - solutions which will have been tried and tested beforehand on the model.
This paper outlines the mathematical equations underlying model design, demonstrating, in the process, the constraints set by Physical Science on the design, construction and use of the model, which will be crucial to the success of the investigation. The procedure generally adopted in a model-based study is then described, together with recommendations on suitable model materials and on the contents of the report to be submitted to the client.
The final part of this paper deals with pumping stations, treatment works and the more complex network components, respectively. The problems specific to each type of facility are described as well as particular aspects of the modelling procedure on their corresponding models.
