| Outline and Purpose of the Course | This lecture discusses causes and consequences of landslides, and make analyses on mechanisms of slope failure. Numerical modeling techniques for landslide predictions are introduced. | ||
| Course Goals | Analyze the case studies on natural disasters such as flooding in river basins and landslides, and develop the ability to determine the causes and make appropriate predictions. | ||
| Schedule and Contents |
Analysis and modeling of rainfall runoff hydrographs (total: 3 sessions) Session 1: Rainfall runoff characteristics in different river basins Session 2: Developing runoff hydrograph models Session 3: Predicting flood and drought Analysis and modeling of water cycles in forests (total: 5 sessions) Session 4: Water retention and permeability in soil Session 5: Vertical infiltration processes of rainwater Session 6: Saturated throughflow and pipeflow Session 7: Bedrock infiltration and evapotranspiration Session 8: Analysis of saturated and unsaturated infiltration Analysis and modeling of the surface failure process (total: 3 sessions) Session 9: Mechanisms of surface failure Session 10: Prediction of location of surface failure Session 11: Prediction of time of surface failure Field data measurement techniques (total: 3 sessions) Session 12: Measurement of precipitation and soil water content Session 13: Measurement of soil thickness, soil porosity and coefficient of permeability Session 14: Analysis of fluctuation characteristics of measurement data Session 15: Questions about lectures and explanations |

| Evaluation Methods and Policy |
Evaluation will be based on attendance, in-class quizzes, the quality of report, and attitude toward class presentation. Refer to 'Guide to Degree Programs' for attainment levels of evaluation. |
||
| Course Requirements | It is highly desirable that students have studied erosion control engineering and forest hydrology in the Faculty of Agriculture. | ||
| Study outside of Class (preparation and review) | It is recommended that students preview the techniques for preparing simulation codes using programing languages such as FORTRAN, in order to gain a better understanding of the course. | ||
