| Outline and Purpose of the Course | We are having special lectures on sediment yield and transport, sabo techniques and sabo structures to control sediment yield and sediment disasters. Theories and practical techniques are lectured with specific sediment disasters and sabo planning. | |||
| Course Goals | First goal is to study sediment yield, sediment transport, sediment disasters and sabo plannings on basic theories and actual situations. And final goal is to consider and propose the effective sabo planning suitable for the actual conditions. | |||
| Schedule and Contents |
1 to 2 weeks of classes are planned for each of the topics covered in this course, including the following: １．Sediment yield（surface erosion, shallow landslide, landslide）(Kosugi, Nakatani) ２．Sediment transport（bed load, suspended load, debris flow, sediment sheet flow）(Nakatani) ３．Sabo planning（Mitigation of sediment disasters, application to developing countries）(Nakatani) ４．Integrated sediment management（from mountain to coast area）(Nakatani) ５．Sediment control structures（sabo dam or erosion control dam）(Nakatani) ６．Torrent environment conservation（fish, landscape）(Nakatani) ７．Moral for sabo and environment engineers (Nakatani) |

| Evaluation Methods and Policy |
Report examination (60%); class performance (40%) Class performance includes attendance and grades earned in short reports assigned every 2 to 3 classes. Refer to current year's 'Guide to Degree Programs' for attainment levels of evaluation. |
|||
| Course Requirements | It is recommended that Sabo engineering and Forest hydrology have been taken in under graduate courses | |||
| Study outside of Class (preparation and review) | Before the class, collect information about sediment disasters and disaster prevention works in Japan and other countries. After the class, students will notice that disasters and prevention works are related to governments, engineers and local residents. Try to consider effective way to tell the residents about the disasters from the points of governments and engineers using the knowledge from this class. | |||
| Textbooks | Textbooks/References | Materials are handed out in the class. | ||
