Název v původním jazyce

Dynamics of dangerous substances and study of resuspendation of polluted sediments

Popis výsledku v původním jazyce

The dynamics of dangerous pollutants in streams originates of the movement of suspended load. The total amount of it is related to washing-up processes in the watershed, the sludge outlets and re-suspended sediments. Three new empirical models are presented for estimation of suspended-load transport. Moreover, using regressions between concentration of suspended load and concentration of pollutants in it, the transport of different pollutants may be computed. The re-suspension of cohesive sediments maybe well described by two-dimensional mathematical model with imputed criterion for the velocity of re-suspension of sediments dependent on the local mean velocity of the stream. This way of modeling enables the estimation of the amount of re-suspended sediments during any flood event even in a very complicated river bed geometry.
