Cross drainage on Road

 In an irrigation project, once the network of main canals, branch canals, distributaries, etc. square measure provided, then these canals could be got to cross the natural drainages like rivers, streams, nullahs, etc. at totally different points among the command space of the project. The crossing of the canals with such obstacles can't be avoided. So, appropriate structures should be made at the crossing purpose for the simple flow of water of the canal and emptying within the several directions. These structures square measure called cross-drainage works.

The necessity of Cross-drainage works:

-The water-shed canals don't cross natural drainages. however, within the actual orientation of the canal network, this ideal condition might not be offered and obstacles like natural drainages could also be gift across the canal. So, cross emptying works should be provided for running the irrigation system.

-At the crossing purpose, the water of the canal and therefore the emptying get intermixed. So, for the graceful running of the canal with its style discharge the cross emptying works square measure needed.

-The site condition of the crossing purpose could also be such with none appropriate structure, the water of the canal and emptying cannot be amused to their natural direction. So, the cross emptying works should be provided to keep up their natural direction of flow.
