摘要

潮汐闸已经运行了几个世纪，以阻止海水渗透景观，而风暴闸是相对较新的。风暴闸门只是阻挡严重的风暴潮，而通常保持开放，让海水随潮汐自由地来回移动。本研究评估了在非通航的沿海河流和小溪上设置闸门的成本和防洪效益(避免洪水损失)。研究发现，只有一小部分沿海河流应该有防风闸门。但选定的风暴闸门非常有效，其长期效益是其成本的三倍。在适当的地方，防暴门可以保护脆弱的低洼发达地区免受沿海洪水的影响，同时对环境的影响最小。

The Economics of Storm Gates

Abstract Tidal gates have been in operation for centuries to block salt water from penetrating landscapes, while storm gates are relatively new. Storm gates block just severe storm surges while normally remaining open to allow salt water to move freely back and forth with the tides. This study evaluates the cost and flood benefits (averted flood damage) of storm gates on non-navigable coastal rivers and creeks. The study finds that only a fraction of coastal rivers should have storm gates. But selected storm gates are highly effective with long term benefits that are three times their cost. In the right place, storm gates can protect vulnerable low-lying developed areas from coastal flooding with a minimal environmental footprint.

期刊介绍： Coastal Management is an international peer-reviewed, applied research journal dedicated to exploring the technical, applied ecological, legal, political, social, and policy issues relating to the use of coastal and ocean resources and environments on a global scale. The journal presents timely information on management tools and techniques as well as recent findings from research and analysis that bear directly on management and policy. Findings must be grounded in the current peer reviewed literature and relevant studies. Articles must contain a clear and relevant management component. Preference is given to studies of interest to an international readership, but case studies are accepted if conclusions are derived from acceptable evaluative methods, reference to comparable cases, and related to peer reviewed studies.
