Detailed Solution
Download Solution PDFDuty: It is the number of hectares of land irrigated for full growth of a given crop by a supply of 1 cumec of water continuously during the entire base period of that crop.
Duty of water changes from place to place, it will be maximum at the field and minimum at the head of the main canal.
Duty is the area that can be irrigated by the discharge of 1 cumec of water.
At the head of the canal, there are numerous losses to occur later which requires more amount of water to irrigate a particular field. However, if considered on the field, all losses have already occurred and a lesser amount of water is required to irrigate the same considered area.
