STANDARDS OF CANAL CROSS-SECTION

## Standards of canal cross section

STANDARDS OF CANAL CROSS-SECTION Usual dimensions of canal cross-section elements have been given here and there inappropriate articles. The standards as suggest by CWPC are given as follows.   1. General. A trapezoidal section is recommended for the canal. The longitudinal slope of the canal is determined depending upon the average slope. The natural ground along the proposed alignment. This is the maximum average slope that can be provided on the canal. 2. Side Slopes. These are dependent on the local soil characteristics and are designed to withstand. The following conditions during the operation of the canal. (a) The sudden drawdown condition for inner slopes. (b) The canal running full with banks saturated due to rainfall. Canal in the filling will generally have side slopes of 1.5: 1. For canals in cutting, the side slope should be between 1: 1 and 1.5: 1 depending upon the type of soil. 3.…
