摘要: Abstract This study developed a new framework to quantify spatial vulnerability for sustainable water resources management. Four hydrologic indices – potential flood damage (PFDC), drought (PDDC), quality deterioration (PWQDC), and watershed evaluation index (WEIC) were modified damage, deterioration, overall risk considering the impact of climate change, respectively. The concept sustainability in Driver–Pressure–State–Impact–Response (DPSIR) was applied selecting all appropriate indicators (criteria) change impacts. In examination future meteorological data obtained using CGCM3 (Canadian Global Coupled Model) SDSM (Statistical Downscaling Model), stream run-off simulated HSPF (Hydrological Simulation Program — Fortran). four then calculated TOPSIS, multi-attribute method decision analysis. As result, ranking can be changed consideration represents attempt manner that takes into account both impacts sustainability.
