Soil Loss Calculations

Use the Idaho Soil Loss Computation Spreadsheet to assist with calculating concentrated flow and ephemeral gully erosion, classical gully erosion, streambank erosion and mass movement.  There is also an alternative method to calculate gross soil loss from cropland fields where significant rill erosion occurs.
