| This paper quantifies the transformed effectiveness of alternatives for
watershed management caused by climate change and urbanization and
prioritizes five options using multi-criteria decision making techniques. The
climate change scenarios (A1B and A2) were obtained by using a statistical
downscaling model (SDSM), and the urbanization scenario by surveying the
existing urban planning. The flow and biochemical oxygen demand (BOD)
concentration duration curves were derived, and the numbers of days required
to satisfy the environmental flow requirement and the target BOD
concentration were counted using the Hydrological Simulation Program-Fortran
(HSPF) model. In addition, five feasible alternatives were prioritized by
using multi-criteria decision making techniques, based on the driving
force-pressure-state-impact-response (DPSIR) framework and cost component.
Finally, a sensitivity analysis approach for MCDM methods was conducted to
reduce the uncertainty of weights. The result indicates that the most
sensitive decision criterion is cost, followed by criteria response, driving
force, impact, state and pressure in that order. As it is certain that the
importance of cost component is over 0.127, construction of a small
wastewater treatment plant will be the most preferred alternative in this
application. |
