Helpful, I am looking over detail.  The paper I read years back suggested landslide in mountain was caused (such as by dynamite) and landslide and gully erosion and sediment deposits were caught in the valley dam created.  It sounded extreme at the time to do this to landscape, but in places where wet bottomlands are needed for food, I thought the hungry farmers with families might have justified it.  I just waned to know the benefits (food) as well as the negatives (such as eventual dam failure and downstream destruction). Or was the practice sustained, such as with an overflow channel installed to handle floodwaters and prevent failure?  Is it a useful practice, applied in perhaps rare circumstances, or just a bad practice, too many impacts?

There is the AGU "Water Resources Monograph 18: Landslides: Processes, prediction, and land use" that could be useful for your research.
