One promising approach to treat sediment-laden turbid water is to introduce chemical flocculants into the turbid water, causing the suspended solids to flocculate. The most common flocculant is polyacrylamide (PAM), but chitosan-based biopolymer has potential to be used for the turbidity control (Orts et al., 2000, Sojka et al., 2007). PAM is a

Therefore, slope is a critical factor in determining a PAM rate for reducing soil erosion and should be considered for proper application.
