Test in Universe: Drought plan in operation

WMO and GWP drought guidelines use several monitored indicators to trigger mitigation and response, while each plan sets its own stages, thresholds and measures.

1. 01 Indicators

   1. 01مخزون الخزاناتDataset · Disclosure regulatorReservoir and lake levels are among the physical indicators to monitor, reflecting drought impacts on water users.
   2. 02Rainfall index (SPI)مجموعة البياناتThe Standardized Precipitation Index uses monthly precipitation over time scales from 1 to 24 months, each suited to a different drought.
   3. 03Groundwater levelsمجموعة البياناتGroundwater levels are monitored with reservoir levels and streamflow. Long-term SPI values are tied to streamflow and groundwater.

2. 02 Plan

   1. 04Drought stageGate · Disclosure regulatorMultiple drought indices trigger mitigation and response, and areas are subdivided so stages follow severity. The plan sets the stages.

3. 03 Measures

   1. 05Allocation rulesStep · Disclosure regulatorA plan can set how water is shared between user classes at each stage, agreed before the drought. The guidelines do not set the rules.
   2. 06Demand restrictionsخطوةA plan can pair stages with demand-reduction measures and public notice. The guidelines do not set the measures.
   3. 07Environmental flowخطوةA plan can set a minimum flow for downstream ecosystems. This is water-resources practice, not from the drought guidelines read.

4. 04 Review

   1. 08Monitoring and forecast reviewالنموذجMonitoring continues through the drought. Review frequency is set by the plan.
   2. 09Step up or exitDecision · Disclosure regulatorThe responsible body decides whether to move to a higher stage or end the response, and records the decision. The body is set by the plan.
