- Abstract
This study proposes a novel optimization system to assess ecological flow regime in which ecological requirements of river inflow as well as wetland are integrated for sustainable water supply. Fuzzy hydraulic habitat simulation was used to assess hydraulic habitat losses of the river ecosystems. Furthermore, an ANFIS-based data-driven model was applied to assess ecological status of the wetland ecosystem. Then, the ecological models were utilized in the structure of an optimization system in which three objectives were considered including (1) minimizing water supply loss, (2) minimizing ecological impacts in river ecosystems, and (3) minimizing ecological impacts in the wetland ecosystem. Based on case study results, average root means square error for habitat loss is 20% in the river habitats which means the model is able to mitigate impacts on the ecosystem. Moreover, ecological water level in the wetland is improved. The performance of the optimization model was acceptable in terms of water supply for farms because it can provide the 50% of the ideal farmers' revenue in the study area. The model can balance the ecological requirements and the benefits for the farmers fairly which means it is recommendable to apply it for integrated management of river and wetland ecosystems to provide sustainable water supply.
