可持续发展可定义为不降低生活质量。结合可持续发展研究防洪问题,一方面,洪水破坏人类遗产和危害可持续发展,另一方面,按照可持续发展的通常解释,人们不应选择那些可能被后人视为不恰当防洪方案的防洪政策。有些大型防洪工程通常就是这样审查的。非工程措施比较符合可持续发展的要求,更为可逆,能被人们普遍接受,不破坏环境。这些措施包括源头控制(流域/景观工程管理)、法规(包括区划)、经济手段、有效的洪水预警系统、洪水风险评估系统、提高洪水风险意识和洪水相关数据库等。在大多数脆弱地区,仅靠工程措施不能实现洪水安全,必须通过非工程措施进一步降低洪水风险,即只有因地制宜地将工程与非工程措施结合,才可能适当解决洪水安全问题。由于可持续发展需要考虑到后代,因此气候变化问题十分重要。非工程措施可应用于适应气候变化的策略。气候变化影响评估具有较大的不确定性,因此所采用策略的灵活性特别重要。
Sustainable development can be defined as not degrading the quality of life. On the one hand, flood damage to human heritage and endanger sustainable development, on the one hand, and sustainable development, on the other hand, should not be chosen for flood prevention that may be considered by some to be inappropriate flood protection schemes policy. Some large-scale flood control projects are usually reviewed in this way. Non-engineering measures more in line with the requirements of sustainable development, more reversible, can be generally accepted, without damaging the environment. These include source control (basin / landscape management), regulations (including zoning), economic instruments, effective flood warning systems, flood risk assessment systems, awareness raising of flood risk and flood related databases. In most vulnerable areas, flood safety can not be achieved by engineering measures alone. The risk of floods must be further reduced through non-engineering measures, that is, flood safety problems may be appropriately addressed only if the combination of engineering and non-engineering measures are tailored to local conditions. As sustainable development needs to take account of future generations, the issue of climate change is very important. Non-engineering measures can be applied to adapt to climate change strategy. The climate change impact assessment has greater uncertainty and therefore the flexibility of the strategy adopted is of particular importance.
