Aim. Assessment of damage to aquatic bioresources.Methods.This article presents the results of testing of the simulation mathematical model of propagation of suspended particles to determine the areas of increased turbidity in the assessment of damage to Cherek River water biological resources because of Nizhne-Cherek HPS Cascade exploitation. In order to establish the basic characteristics of annual and seasonal runoff in the hydraulic structures dam locations on the river Cherek are used data on runoff in support hydrological dam locations of the Hydrometeorological Service, generalized in the reference book "Surface water resources."Results. A mathematical model developed on the basis of probability theory and stochastic processes emissions theory, based on the normal law of distribution of horizontal and vertical components of the instantaneous flow velocity and Rayleigh law for the distribution of their peaks is used to calculate the " turbidity plume " in the washing of the head unit settler and deep washing of Kashkhatau HPS head unit.Conclusion. The studies found that the negative impact of "turbidity plume" in the Cherek river will be traced for approximately 3 km.
