This article presents an improved hydraulic calculation method for accurately assessing erosion and deformation processes on the banks of earthen irrigation canals, taking into account the uneven distribution of flow velocities and bed shear stresses across the cross-section. Results from field studies and laboratory experiments on the Amu-Bukhara Machine Canal (ABMC) are provided. A multi-objective optimization model based on the NSGA-II genetic algorithm has been developed to determine optimal geometric parameters for canal reconstruction, ensuring minimal filtration losses and overall costs. This approach contributes to improving the technical reliability of canals in Uzbekistan's water management sector.
