概要KsEdge 2D模型是京都大学开发的分布式水文模型，在日本的许多流域得到了很好的研究和成功的应用。由于该模型最初是利用日本地形和河流网络数据开发的，由于输入地形和河流网络数据格式的差异，不可能适用于国际流域。这项研究提出了扩展的KsEdge 2D模型，使用全球可用的地形数据。开发了名为DEM-V0-Maker的用户友好软件，用于生成KsEdge 2D模型所需的地形和河道网络输入数据。两个盆地，Kamishiba盆地，日本和梅查姆盆地，泰国被选中应用KsEdge 2D模型使用免费提供的地形数据。两个流域的计算结果与实测资料进行了比较，结果显示出良好的一致性。
Synopsis The KsEdge2D model is a distributed hydrological model developed at Kyoto University and it has been well studied and successfully applied for many basins in Japan. As the model was initially developed to utilize the Japanese topographical and river network data, it is not possible to apply for international basins due to the discrepancy of input topographical and river network data formats. This study presents the extension of the KsEdge2D model to use globally available topographic data. User friendly software named, DEM-V0-Maker was developed to generate the required topographical and channel network input data for the KsEdge2D model. Two basins, the Kamishiba Basin, Japan and the Mae Chaem basin, Thailand were selected to apply the KsEdge2D model using freely available topographic data. The results of both basins were compared with the observed data and it showed a good agreement.
