Debris-Flow Research and Engineering Practice

For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews three such complications: the problem of defining debris hydrographs, the effects of variations in debris composition, and the effects of fan geometry on runout and spreading. At present, these complications impede the development of flow frequency relationships and force engineers to oversimplify flow behavior in their models. Research directed toward such complications will permit extension of the advances in debris-flow theory to routine field practice.
