ABSTRACT 



This was a laboratory study of soil erosion, performed 

 on bare soil plots under simulated rainfall. The variables 

 having the greatest effect on erosion by overland flow were 

 rainfall intensity, slope steepness, and the percentage by 

 weight of soil particles greater than 2 mm. The variables 

 having the greatest influence on raindrop splash erosion 

 were rainfall intensity, slope steepness, percentage by 

 weight of soil particles between 60 and 2,000 microns, and 

 soil bulk density.
