This course is an advanced course built upon the course of "Soil Erosion" given at undergraduate level. This course consists of three parts. The first part will be concentrated at the mechanics of erosion; the concepts of soil loss estimation model will be taught in the second part of this course; whereas several soil loss estimation models will be introduced in the last part of this course. Graduate students will pick up the skills from learning-by-doing at the end of the semester through online practices so that the international linkage of erosion as well as soil loss estimation will be established.
