Evaluation du fonctionnement des déversoirs d'orage latéraux par le logiciel de modélisation "calDO".

Abstract

The knowledge of the real hydraulic operation of the outfalls of storm is one of the main issues today if one wants to succeed in limiting the pollution brought to the natural environment, in more it is paramount in any study of diagnosis or dimensioning of the networks of cleansing. For this purpose, this work was interested in modeling of operation of the outfall of storm of Ben Aknoun by being based on the software “calDO” in order to hydraulically diagnose their operation in particular in times of rain. We calculated the flow poured according to the flow upstream, the watermark along the overflow crest, the curve of operation of the outfall like its flow of reference and at the end one noted that the operation of outfall of storm is satisfactory.
