Researchers conducted studies to understand erosion on highways and how to stabilize it effectively. They focused on factors affecting runoff, erosion, and sediment production from highway cuts. Measurements showed soil loss varied from 25 to 359 tons per acre annually. Frost action and bank orientation were major contributors to erosion. Vegetative cover, especially mulching, was found to be crucial for stabilizing steep slopes. Crownvetch was identified as the most effective plant for roadside vegetation.
