जल संतुलन जलाशय: नहर कमान में एक कुशल जल भंडारण संरचना
Water balancing reservoir is also known as Diggies or Tanks or Farm pond or intermediate storage structures in canal command. It is a water storage structure in canal command to store the water delivered from the water courses to farms and regulate the flow of water for agricultural irrigation.
Water is pumped out of this and is distributed to the field through channels or micro irrigation system. It helps to supply irrigation water when the crop requires it, the most. All these interventions contribute to higher yield, production and water productivity.
However, water balancing reservoirs are shown to be cost-effective for landholdings above 4 ha. Thus, it can directly help medium to large fully irrigated landholdings. In India, 8 % of the irrigated landholdings are in this category and they account for 24 % of the irrigated land.
The right combination of water balancing reservoir or tank with canal command areas as inlet and micro-irrigation as outlet hold the key to achieve high yield and better quality of produce.
Need of water balancing reservoir in the canal command areas
Water balancing reservoir is very important water harvesting structure in canal command to meet the demand and supply of water to agricultural farm. It is advantageous in...
