polyacrylamide ( anion and cation ) for preventting soil erosion
Using Polyacrylamide (PAM) to Reduce Erosion on Construction
Therefore, erosion control should always begin with protecting the soil from rain droplets and slowing overland flow by using mulch and vegetation. PAM does not directly protect soil from rain droplet impacts, but it reduces soil detachment, maintains the soil's structure, and increases infiltration rates early in the rain event.

PAM in Furrow Irrigation, an Erosion Control Breakthrough
Divalent cations in water bridge the PAM and soil, increasing soil cohesion and strengthening aggregates contacted in the furrow (De Boodt, 1990; Barvenik, 1994, Sojka and Lentz, 1994b). Soil particles at the furrow's soil-water interface are bound together, preventing detachment and transport of sediments in runoff.

PDF Polyacrylamide (PAM) – michigan.gov
Polyacrylamide (PAM) Definition Polyacrylamides (PAMs), are polymer-based materials used to facilitate erosion control and decrease soil sealing by binding soil particles, especially clays, to hold them on site. In addition, these types of materials may also be used as a water treatment additive to remove suspended particles from runoff.

PDF Soil Infiltration and Erosion Polyacrylamide Molecular Weight
Amendments such as gypsum (or phosphogypsum, PG) and anionic polyacrylamide (PAM) have been used to prevent seal formation, runoff and erosion from a wide range of soils (e.g., Levy and Sumner, 1998; Sojka et al., 2006). Use of PG is effective because upon dissolution PG releases electrolytes into the soil solution thereby
The anionic form of linear, water-soluble polyacrylamide is frequently used as a soil conditioner on farm land and construction sites for erosion control, in order to protect the water quality of nearby rivers and streams. The polymer is also used to make Gro-Beast toys, which expand when placed in water, such as the Test Tube Aliens.
