Table 1.

Detailed information of the different environmental flow policies and related scenarios.

Policy Scenarios Hypothesized Conditions
1. Fraction of Inflow (FOI) Scenario 1, FOI = 0.1;
Scenario 2, FOI = 0.2;
⁞
Scenario 9, FOI = 0.9.		 This policy offers a promising way that allows for extensive trade-offs between water supply for human and environmental flow requirement.
2. Flow Components (FC) Scenario 1, 10% of ADF as e-flow during dry season and 30% during the wet season, and 3*1 high-flow events;
Scenario 2, 10% of ADF as e-flow during dry season and 30% during the wet season, and 3*2 high-flow events;
 ⁞
Scenario N (N = INT[the total number of high-flow events/3]), 10% of ADF as e-flow during dry season, 30% during the wet season, and 3*N high-flow events.		 This policy attempts to provide occasional high-flow releases for habitat improvement.
3. Four-period release approach (FP) Scenario 1, (i) Floods: bankfull discharge as e-flow; (ii) Base flows: 10% of ADF as e-flow during the dry season and 30% of ADF during the wet season; (iii) Extreme low flows: e-flow equals to the reservoir inflow; (iv) High-flow pulses: all high-flow are released. This policy attempts to provide the full range of natural flow regime alterations, including floods and droughts, in which the riverine ecosystem is adapted.
