dc.description.abstract The paper presents a way of analyzing the erosion phenomenon of riverbeds. Theoretical study and experimental research was carried out on a sector of the Moldova River in the area of Sochi, Iasi County. The study of the stability of the river bed was carried out by analyzing the value of the shear stress on the perimeter watered in characteristic cross sections. The river bank has been measured topographically in transverse and longitudinal profiles positioned on the river section (at the entrance, exit, and imposed sections). For analysis of bed stability was determined the wet perimeter distribution of the hydraulic parameters (v, h and n) in the imposed sections. For the study of the erosion of the bed, a theoretical hydraulic-mathematical model was developed. The analysis model resolves in the first stage the equation of the progressive variable fluctuations in riverbeds by the finite difference method. In the second stage, shear stresses are determined at characteristic points on the perimeter of the bed. The hydraulic - mathematical model (coded MPGV_ River_Bed.m) was solved in the MATLAB programming environment. The obtained results allowed the erosion zones to be highlighted in the river bed. en_US
