平成25年度JICA研修の英語資料を公開します
(JICA training materials for watershed management and flood control in 2013)

平成２５年６〜８月に行われたJICA帯広事務所主催の研修「気候変動に対する順応的流域管理：洪水対策と生態系保全」にて当研究所で担当した「流域分析」、「氾濫シミュレーション」に関する英語研修資料を公開致します。研修の詳細につきましては月報第725号をご覧ください。 We provide workshop materials used in the JICA training programs for watershed management and flood control in 2013. (1) Identifying watershed areas and land usage 1. Creating a river basin in Philippine with SRTM and Landsat images [pdf], [DATA 315MB] 2. Classifying land usage of the basin [ppt], [DATA 19MB] For the analysis on a watershed, it is crucial to identify watershed border, area and land usage. Firstly, you make a shape file of a watershed by using “Hydrology Tools” of ArcGIS on SRTM data. Then you clip the Land-sat images the wathershed shape file. Lastly, you make MultiSpec analysis on the clipped Land-sat data and classify the land usage. (2) Flood simulation 1. Processing geographic data and simulating Tsunami at Kamaishi, Japan [pdf], [DATA 75MB] 2. Simulating flood in the Shire River, Malawi [pdf], [DATA 38MB] 3. Simulating flood in the Aceh River, Indonesia [pdf1], [DATA1 33MB], [pdf2], [DATA2 19MB] In order to make flood control plans such as river works and relocation, flood simulation is a useful tool. Firstly, you make the SRTM data into an area you need by using the tool “Clipper” of QGIS. Then you import the clipped data as a geographic data into the iRIC. Lastly, you input some hydraulic conditions such as inflow hydrograph and roughness, and do a calculation.
