Water Resources Management — Revision Notes

⚡ 30-Second Revision

Basin ≠ administrative boundary.
Withdrawal − recoverable returns is not automatically a universal consumption formula; state the boundary.
Example: 100/60/40 → 80/60/20 leaves consumption unchanged.
Aquifer extraction is rival.
Policy adoption: 28 December 2012.

2-Minute Revision

Water management combines physical accounts with allocation, access and governance. Return flows and scale changes can alter the meaning of efficiency claims. Distinguish the hydrological unit from jurisdiction, and evaluate interventions through quantity, quality and distribution rather than a withdrawal figure alone.

5-Minute Revision

Explain the 100/60/40 to 80/60/20 water-balance example, stating its recoverability assumption. Then change the scenario so irrigated area expands and identify the additional measurements needed before claiming a basin saving.
