Reservoir-type water source vulnerability assessment: a case study of the Yuqiao Reservoir, China

In this study, we developed a method to assess reservoir-type water source vulnerability (WSV) and adapted the method to the Yuqiao Reservoir (in Tianjin in North China). First, we identified the factors that influence reservoir vulnerability and selected suitable indexes for vulnerability assessment. Second, the CRITIC, AHP and integrated weighting methods were applied to quantify the index weight. Third, the information diffusion method was applied to process the index data. Finally, the vulnerability of the Yuqiao Reservoir was assessed, and the results showed that the vulnerability of the Yuqiao Reservoir is high, with social factors (i.e. the road traffic system, automatic management control system, potential menace in evaluation scope, destructive man-made accidents, emergency management plan, and per capita water consumption) being the main reasons.
