The command area of irrigation refers to the specific extent of land that can receive a reliable supply of water from a designated water source.
Understanding the Command Area (CA)
As defined, the command area, often abbreviated as CA, of a water source represents the extent of area which can be reliably irrigated from that source. This definition highlights the crucial aspect of water availability and its direct impact on the land area it can serve for irrigation purposes.
What is Reliable Irrigation?
Reliable irrigation is a key component in determining the command area. According to the definition, reliable irrigation means that the availability of water is always larger than or equal to the irrigation need of a scheme. This ensures that the crops within the command area receive sufficient water consistently, without shortages, allowing for successful agricultural activities.
In essence, the command area is the land explicitly designated and capable of being supplied with water from a specific dam, reservoir, canal, or other water source, under the condition that the water supply is dependable enough to meet the irrigation demands of that area.
