Abstract

Optimum value of the radius of curvature to be provided to join the bed of a trapezoidal channel with side slopes has been worked out, to minimize the head loss in the channel. It has been found to be equal to 0.4 R, where R is the mean hydraulic radius of the channel, for all values of side slopes. Provision of curves with a radius equal to the depth of the channel has been found to increase the head loss instead of decreasing it, thus defeating the very purpose for which it is provided.
