The kinematics of flow movement in the forebays pumping stations significantly influence efficiency pump operation. This study addresses issue sediment accumulation caused by improper velocity distribution intake structures stations. Research was conducted at water structure Uzbekistan’s Dehqonobod station, located Quva district, Fergana region. involved analyzing hydrodynamic processes within based on principles fluid motion, combining experimental approaches with simulations using COMSOL Multiphysics software suite to develop a 3D structural model prototype structure. Additionally, numerical were performed Newton-Raphson scheme and realizable k-ε turbulence for comparative analysis evaluation. To ensure proper distribution, six vertical columns arranged triangular pattern relative movement, spacing 1 meter between them. arrangement proposed so as enhance technical economic efficiency. results demonstrated that installation increased near right left walls forebay, achieving variation up 20%. Specific recommendations developed optimize conditions improve station's operational
