The design standard of structural engineering measures could not stand with the extremely intensified flood disasters. In addition, such structural engineering measures might mislead the public that such areas are safe. In fact, urban stormwater integration planning and management has been implemented in the worldwide. After setting the flood protection "protection standards" for the region, the plan is adopted according to the standard. As a whole, it is the key to setting a reasonable, objective and scientific regional "protection standard" for the city. Therefore, the study will then clarify the theoretical connotation of “protection standards” and collect domestic and foreign past protection standards. Afterwards, the study will then develop a framework for “protection standards” suitable for operation in Dali River Basin in Taiwan. The cost-benefit analysis will then be applied to do the calculation.enGlobal Climate ChangeProtection StandardCost-Benefit AnalysisFloodsArticle1770-1779
