Regime Approach to the Design of Drainage Channels

In designing any water conveyance channel the engineer is very much concerned that the cross-section and slope of the channel will remain stable, thereby reducing maintenance costs and avoiding disruption to adjacent land by bank erosion and shifting of the channel course. The Regime method was originally developed in the Indo-Gangetic plain for the design of large irrigation canal systems so that they remained reasonably stable and free of operational problems. It must be remembered however that, as compared with drainage channels and rivers, the discharge in an irrigation canal during the operating season is relatively constant. Accordingly it is not possible simply to translate the Regime method equations for the design of irrigation canals into equations for the design of drainage channels. Some thought has to be given to selecting a characteristic discharge from amongst the whole range of flows which occur in the channel. This paper is not specifically concerned with the straightforward application of Regime method equations, but rather makes use of the regime concept of a channel which is in balance with the water and sediment flowing in it.
