Inundation Canal Systems

Inundation canal systems are constructed along the side of a perennial river. As soon as the flood in the river reaches a certain level, water starts to flow in the canals towards the fields. Just like flood rise irrigation, it makes use of rising water levels.

An important aspect of inundation canal systems is maintenance of the canals. Sediments can make the level of the canals rise or even block the canals so water cannot reach the fields. Maintaining the right depth of the canals is very labour intensive but necessary to create a productive system.
