Using Polyacrylamide (PAM) to Reduce Erosion on Construction
Dry granules have been applied directly with limited success, but dissolved PAM is more reliable because of better distribution and soil contact. Overall considerations for using PAM to augment erosion control include: PAM should not be applied alone for erosion control, but in combination with mulch and seeding.

How to Prevent Soil Erosion: 15 Steps (with Pictures) – wikiHow
How to Prevent Soil Erosion. Erosion is the loss of soil. As soil erodes, it loses nutrients, clogs rivers with dirt, and eventually turns the area into a desert. Although erosion happens naturally, human activities can make it much worse. Plant grass and shrubs. Bare soil is easily swept away by wind and water, the
Causes of Soil Erosion | Water and Wind Erosion Causes
Erosion by Water. Rainfall Intensity and Runoff: The impact of raindrops will break up the soil and water build-up will create runoff, taking sediment with it. Soil Erodability: Based on the characteristics of each unique soil, it is more or less susceptible to erosion. Recurring erosion is more typical for soil in areas that have experienced erosion in the past.

"Soil erosion is one form of soil degradation. Soil erosion is a naturally occurring process on all land. The agents of soil erosion are water and wind, each contributing a significant amount of soil loss each year. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing serious loss
