While deciding the alignment of a proposed canal taking off from a river at B, three alignments of approximately equal lengths are available. These cross a drainages at C1, C2and C3 where drainage bed levels C1 > C2 > C3, you will provide at site C3

Irrigation engineering is the process of artificially supplying water to the soil in order to grow crops. It is the science of designing and planning an efficient, low-cost irrigation system that is tailored to natural conditions.

Irrigation engineering is also being used to research water recycling methods and develop new ways of minimizing water seepage and evaporation loss.
