The main task of the design of earthen channels is to calculate the dimensions of thestable channel shape in which irreversible deformation of the channel cross-section does not occur.This article provides information on calculating the hydraulic parameters of a stable channel shapein the design of earthen channels in which channel deformation does not occur.In this case, the need to adopt dynamic stable channel parameters that can work in harmonywith nature through the method of checking the dynamic stability of the channel with the help ofhydraulic modeling programs is based on modeling using HEC-RAS software and field-experiencedata.Based on the research results, a new approach is required in the hydraulic calculation for thedesign of the earthen canals, taking into account the changing nature of the flow and discharge.Taking into account the natural increase of the bottom slope of the deformed channel bed due tosediment deposition, it is suggested to strengthen the side embankments of the channel and choosethe flow slope that ensures the balance of the sediment balance.The essence of the proposed method consists in adopting dynamic stable channel parametersthat are in harmony with nature and do not require continuous cleaning and repair works in thecalculation of earthen channels. For this, it is necessary to model the sediment transport with thehelp of hydraulic modeling programs of the earthen channels.
