How do people speed up the erosion process?

Just add water

...then strip the land

Do you want to cause erosion, or do you want to know what it is people do (on purpose or by accident) which results in erosion?

We do "no-till" farming. We are good stewards of wind erosion.

"No Till" is real big around here. And "Contour Planting" gets quite a bit of play on hilly fields - of which we have plenty.

Up around Great Falls, it's strip farming, but not, I guess for erosion.

I have a feeling that this is either homework or a science fair project. Any soil conservation office of any county in the US has a BMP manual (best management practices). In there they have ideas for control of erosion and sedimentation .Stufflike

1 post construction scouring of land so it isnt compacted and water can infiltrate rather than run off

2riparian buffers so you dont cut down the natural stream side vegetation (These plants act as a filter)

3 Using biofilters for stormwater catchment and ditribution

4 control of storm water by promoting natural levees

5 farming practices like weve already discussed

6 Keeping paved surfaces to the absolute minimum or using permeable pavements

7 dont allow combined sewer/storm water conveyance

8 keep public water and sanitary lines in good maintenance

9 grassy waterways and natural conveyances are better than pits and ponds

10 clearcutting has a price in increased erosion and sedimentation

I cant think of any more but there are a whole slew.

how bout examine the drainage system to see how changes will effect waterflow

I'm quite a big fan of groins

and gullies
