What we have learnt
- 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.
Key Concepts
- -- 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.
