DETERMINATION OF THE KINETIC ENERGY COEFFICIENT IN THE ZONE OF LOCAL EROSION OF THE EARTHEN CHANNEL CONNECTED TO THE LOWER REACH

Abstract

The study focuses on analyzing the kinetic energy of the water stream flowing from spillway structures and its potential to cause erosion in the downstream channel. When water is discharged through a spillway, a large amount of kinetic energy is generated, which can directly erode the channel bed and banks located behind the structure. This process poses a serious threat to the stability and durability of hydraulic structures. The research emphasizes the importance of protecting the downstream channel from erosion through appropriate engineering solutions. Special hydraulic calculation methods were applied to determine the flow velocity and energy distribution behind the spillway. Based on the obtained results, recommendations for effective energy dissipation and channel reinforcement are proposed. The study aims to enhance the safety, reliability, and efficiency of spillway structures by preventing erosion and maintaining the stability of the downstream channel.
