Effects of gravel on infiltration, runoff, and sediment

Results indicated that there was a threshold in proportion of gravel controlling the infiltration, runoff, and sediment yield in the hydrological and erosion processes in the landslide deposit. Greater proportion of gravel promoted infiltration capacity but reduced runoff generation and sediment production when proportion of gravel was higher

Preventing Washboarding U.S. Roads

The ideal blend produces a gravel that will compact into a dense, tight mass with an almost impervious surface. This will reduce washboarding dramatically. Perhaps the least understood factor in obtaining good surface gravel is the right percentage and quality of fine material. This is the percentage of material that passes the #200 sieve.
