8.6.5. Schedule of Area Statistics and Channel Dimensions The calculations for the design of an irrigation channel are usually carried out in tabular form. The table containing these calculated values is called the ‘schedule of area statistics and channel dimensions’. The calculations start from the tail end and the design is usually carried out at every kilometre of the channel downstream of the head of the channel. Intermediate sections are designed only in special circumstances such as a large reduction in discharge due to an offtaking channel in between the adjacent two sections. Example 8.10 illustrates the procedure for the preparation of schedule of area statistics and channel dimensions for an irrigation channel.
