Water is crucial for energy production, agriculture, and flood control.
Effective management of surface water supply is essential for sustainable water use.
Irrigation requirements vary by crop type, reflecting the need for efficient water management.
Water Withdrawals
The total amount of water extracted for various purposes, including agriculture and energy production.
Duty and Delta
Duty is the area irrigated per unit flow of water, while delta is the total water depth needed by crops during their growth period.
Irrigation Methods
Various techniques used to supply water to crops, including surface, sub-surface, sprinkler, and drip irrigation, each with its advantages and limitations.
Consumptive Use
The total amount of water lost through evaporation and transpiration by crops throughout their growth cycle.
