利用综合水力学模型，我们评估了北江（日本福井县）和阿多江（日本滋贺县）的开放式堤防的减灾功能。结果表明，明堤系统不仅能有效降低规划基准点的洪峰水位，而且能有效防止干流决堤，排除内涝和洪水，限制洪水淹没面积。在社会实施方面，提出了以流域减损量来评价开放式堤防的效果。我们还建议，开放的堤防，应与传统的和不变的河流规划在河流低的流域和洪泛区的其他对策分开的规划系统。
Using the integrated hydraulic model, we evaluated the disaster reduction functions of the open levees in the Kita River (Fukui Pref. Japan) and Ado River (Shiga Pref. Japan). As a result, it was clarified that the open levee system is effective not only in lowering the peak water level at the planning reference point, but also in preventing embankment breakage of the main river, draining inland and flooded water, and limiting the flooded area. For social implementation, it was proposed that the effect of open levee should be evaluated by the amount of damage reduction in the river basin. We also suggested that the open levees should be managed with a planning system separate from the traditional and unchanging river planning under River Low like other countermeasures in watershed and floodplain.
