Detailed Solution

In the flood plains of West Bengal, people developed an Inundation channel to irrigate their fields.
Inundation channels are used in West Bengal. In Bengal, there are certain flood regions. In the flood plains, water is collected through Inundation channels and transferred from the inundation channel to the fields. Inundation channels are used to collect water in flooded and rainy areas. By this, water is utilised from flood plains to the fields. There are certain fishes in the flood water that are also collected. Those fishes and larvae are used to treat mosquitoes. This technique allows mosquitoes to be controlled, which can also control dengue and malaria. People in Bengal used this technique for irrigation of fields and controlling floods.
