However, to determine the rate of siltation of reservoirs, we need to know the weight of suspended particles per unit volume (concentration). Based on research conducted at the reservoir Des obtained correlations between measurements obtained with the nephelometer and the concentration of suspended solids (TSS).stream turbidityconcentration of the weighed particleszaileny reservoirsмутность потокаконцентрация взвешенных частицмутномерзаиление водохранилища
