The proper consideration of the filtration process is one of the most significant and challenging challenges in the design of earthen channels. The hydraulic properties of the current channels and the makeup of the channel soil must be considered in order to lower the cost of filtration in unlined channels. The quantity of filtration taking place in the soil bed is calculated when both sides of the channel are coated with concrete. Additionally, it was shown that utilizing a screen constructed of the local raw bentonite clay as an anti-filter coating in unlined channels can greatly minimize the amount of filtration, based on the measured values. The article outlines how to choose a theoretical foundation in the right way for reducing filtration costs
