- Abstract
This study presents a new methodology not only to evaluate willingness to pays (WTPs) for the improvement of hydrological vulnerability using a choice experiment (CE) method but also to do a cost-benefit analysis (CBA) of some feasible alternatives combing the derived WTPs with an alternative evaluation index (AEI). The hydrological vulnerability consists of potential streamflow depletion (PSD), and potential water quality deterioration (PWQD) and can be quantified using a multi-criteria decision making technique and pressure-state-response (PSR) framework. PSD and PWQD not only provide survey respondents with sufficient site-specific information to avoid scope sensitivity in a choice experiment but also support the standard of dividing the study watershed into six sub-regions for site-fitted management. Therefore CE was applied to six regions one after the other, in order to determine WTPs for improvements on hydrological vulnerability considering the characteristics which are vulnerability, location, and preferences with regard to management objectives. The AEI was developed to prioritize the feasible alternatives using a continuous water quantity/quality simulation model as well as multi-criteria decision making techniques. All criteria for alternative performance were selected based on a driver-pressures-state-impact-response (DPSIR) framework, and their weights were estimated using an Analytic Hierarchy Process (AHP). In addition, the AEI that reflects on residents' preference with regard to management objectives was proposed in order to incite the stakeholder to participate in the decision making process. Finally, the economic values of each alternative are estimated by a newly developed method which combines the WTPs for improvements on hydrologic vulnerability with the AEI. This social-economic-engineering combined framework can provide the decision makers with more specific information as well as decrease the uncertainty of the CBA.
