Designing gully control systems for eroding watersheds

Effective design of gully control systems must consider the gully network as a whole and be based on geomorphologie indicators such as type of network, stream order, and stage of development. Consideration of geomorphologic characteristics allows a ranking of gully treatment priorities that, in turn, promises the highest return for expenditures. Relationships between sediment catch, channel gradient, treatment cost, and height of check dams in a treatment system are presented. Return is considered within a physical rather than economic framework. Future soil savings are the main focus.
