For the most economical trapezoidal section of a channel with regards to discharge, the required condition, is
Hence conditions for most economical trapezoidal section are: 1. b+2ny2=y√n2+1 (i.e. Half of top width = One of the sloping sides) 2. Hydraulic radius, R=y2 3. A semicircle drawn from O with radius equal to depth of flow will touch the three sides of the trapezoidal channel.
