区域洪水风险管理模型构建及应用
发布时间：2018-10-24 19:45
【摘要】：我国是洪涝灾害频发的国家之一,尤其长江在6-10月降雨量大而次多,极易引发洪灾,严重威胁长江沿岸各区域的安全。如何在气候变化和人类活动双重影响的新情势下合理而有效地进行区域洪水风险管理,是一个值得深入研究的问题。通过构建区域洪水风险管理模型,并将其应用于荆江河段区域,推演堤坝溃口条件下区域内洪水变化过程,并评价出洪水对区域内各要素的影响。所构建的模型可靠、实用且结果合理,能够为区域洪水风险管理和水资源保护、防洪减灾措施的制定提供一定的技术支持。
[Abstract]:China is one of the countries with frequent flood disasters, especially the Yangtze River, which has a heavy rainfall in June-October, which can easily lead to floods and seriously threaten the security of various regions along the Yangtze River. How to carry out the regional flood risk management reasonably and effectively under the new situation of climate change and human activities is a problem worthy of further study. By constructing a regional flood risk management model and applying it to the Jingjiang River reach, the process of flood variation in the region under the condition of dike burst is deduced, and the influence of flood on various elements in the region is evaluated. The model is reliable, practical and reasonable. It can provide some technical support for regional flood risk management, water resources protection, flood control and disaster reduction measures.
