Modèle de lessivage des matières en suspension en milieu urbain

Abstract: Résumé Le présent travail porte sur le développement et la validation du modèle conceptuel RQSM (Runoff Quality Simulation Model). Le modèle RQSM a pour objectif de simuler le lessivage des matières en suspension. Le modèle RQSM considère que l’accumulation est infinie sur les surfaces perméables et imperméables. Il utilise l’énergie cinétique des précipitations pour décrire la mise en suspension des particules solides. Il modélise le transport des matières en suspension à l’aide de la théorie des sy… Show more

“…This is due to a large share of impervious surfaces (51.6–76.0 %), which are easily flushed, and thus, the suspensions, especially organic, in large quantities are transported to the receiver. Such a dependence of the amount of washed out suspensions on the size of impervious areas was already stated by Deletic et al (1997) and Crobeddu and Bennis (2007). Both BOD 5 and suspended solids are dependent on very intensive rainfall (the storm), which is responsible for the flushing of organic matter particles.…”

“…TSS are also responsible for the large presence of heavy metals in the runoff from industrial areas (Fig. 2), since a large amount of chemical elements are associated with particles (Crobeddu and Bennis 2007). The negative correlation of temperature and oxygen content is associated with decrease of the solubility of oxygen in rainwater with the increased temperature.…”
