在中小城市和大城市及其周围地区，城市化正在扩大，这种扩大包括洪水风险高的低洼地区。小流域的洪水风险已经使用精确的数学模型进行了评估。然而，由于数据收集和分析的复杂性，这些模型不能应用于较大的流域。因此，在宏观尺度上的洪水风险和城市周边地区的防洪功能的定量评价，稻田还没有。本文提出了一种区域尺度上评价稻田防洪功能的方法和指标。此外，使用这个系统的全流域管理的一个例子，鬼怒河和Kokai河，这是日本的音河的支流。该方法的适用性进行了评估，使用的数据发生在研究区域的大洪水。
Urbanization is expanding in and around small to medium-sized cities as well as in large cities, and the expansion includes low-lying areas where the flood risk is high. Flood risk in small watersheds has been evaluated using precise mathematical models. However, these models cannot be applied to larger basins due to the complexity of data collection and analysis. As a result, quantitative evaluations of flood risk at macro scales and the flood-prevention function of paddies around urban areas have not been made. This paper proposes a method and an index that can be used to evaluate the flood-prevention function of paddies on a regional scale. In addition, the use of this system for basin-wide management is illustrated by an example for the Kinu and Kokai rivers, which are tributaries of the Tone River of Japan. The applicability of the approach is evaluated using data from a major flood that occurred in the study area.
