Filtration from trapezoidal channels in homogeneous medium
Abstract
Some methods of calculating filtration from channels. In the design of trapezoidal-shaped channels, establishing the magnitude of water loss to filtration is essential. For unlined canals, to which the overwhelming majority of permanent and temporary irrigation canals belong, the question of loss values is usually related to determination of design flow rate under different operation modes. For canals intended for other purposes, which are in the stage of temporary operation before lining, the values of filtration losses play a well-known role in various calculations of hydraulic engineering works. Finally, in artificial colmatage (sealing) of slopes and bottoms of unlined canals, the value of filtration loss is also used in relevant calculations.
