Soil Erosion Control: Four Factors and Practical Fixes

Backyard erosion from rain. Four factors: 1) Agent (water/wind), 2) Particle size (sand resists, clay moves), 3) Porosity (air space absorbs), 4) Slope (steeper = faster flow). Interventions: vegetation intercepts rain, mulch sponges water, barriers on contour (logs, timbers) create terraces, French drains/pipes channel water. City engineering dept may help.

Match fix to problem scale.
