Ephemeral Gullies
• They recur in the same area each time • They frequently form in well-defined,
shallow depressions in natural drainage ways
Ephemeral Gullies

• They are partially or totally erased and filled by tillage operations
Ephemeral Gullies
• They recur in the same area each time • They frequently form in well-defined, shallow
depressions in natural drainage ways • They are partially or totally erased and filled
by tillage operations• Soil is typically removed to the depth of the
tillage layer
Ephemeral Gullies

operations• Soil is typically removed to the depth of the tillage layer• Ephemeral gully erosion is NOT calculated by
RUSLE2
Magnitude of problem
• A special report written jointly by the USDA-ARS and NRCS estimated that 40 percent of watershed sediment yield
• The report also emphasized the need for vastly improved ephemeral gully erosion science that should be based on physical model development.
Landowner outreach
• Outreach to 811 landowners • List narrowed to 50
– Receive map of ephemeral erosion– Offer for grassed waterway design– Follow up with landowner advocate– Provide waterway design
• Survey results
