It becomes a challenge task of water-resources management to find a strategy simultaneously meeting human and environmental water needs. In this study, a multi-level environmental flow is incorporated into a basin-scale simulation model and applied to Hsintien Creek basin located in northern Taiwan to achieve this goal. Two types of indicators comprise human indicators (water-supply, hydropower production, and flood peak attenuation) and environmental indicators (frequency of small floods, annual minimum 7-day flow, monthly flow hydrograph, and coefficient of variation for daily flow) are used to derive the optimal operating strategy. The results show that the current scenario is slightly better than the no environmental flow scenario. The optimal scenario has great improvements in altered natural flow regime, but at a cost of deterioration of human indicators.
