喜马拉雅中部阿润河谷高山环境下的冰湖溃决洪水研究
发布时间：2023-04-02 18:33
冰川湖泊溃决洪水(GLOF)是一种被研究人员广泛认识的自然灾害,其爆发后的巨大破坏能力对自然生态环境和人造基础设施安全等都构成严重威胁。因此,进行GLOF风险评估是非常必要的,特别是在有水电站的流域内,如果不进行GLOF风险评估,可能会造成巨大的社会经济损失。此外,还需要综合汇编水文、地质、地貌和气候数据,以便对水电站等重要项目进行可行性研究和设计研究。值得注意的是,文献中已有很多方法可用于评估冰湖溃决洪水。这些方法通过方法构造的类型、评价特征的数量和选择、评价过程中所需的输入数据和主观性比率来区分,有些是适应环境设计的,有些是设计来适应的。评价程序对输入数据的要求和主观性的要求通常被认为是其重复使用的根本障碍。最近的一项研究考察了这些方法在高山环境中的适用性。结果表明,所采用的方法均不满足所有规定的标准,且需要耗费大量的人力、时间和成本,因此,需要一种新的方法来适用于高山环境中水电项目安全性评估。此外,由于现有的GLOF风险评估方法的主客观局限性,我们提出了一种新的、易于应用的基于历史冰湖溃决洪水流量和影响规模的四步筛选方法,应用范围更广,不需要根据主题区域进行适应变化,这也允许成本...
