The relationship of soil surface roughness with hydrologic variables on natural and reclaimed range land in New Mexico

Soil surface roughness values have been used to predict runoff and infiltration rates from crop lands, forest lands, and range lands. The strength of association between roughness and runoff and infiltration has been weak as shown with correlation analysis. The purpose of this study was to determine...

Summary:Soil surface roughness values have been used to predict runoff and infiltration rates from crop lands, forest lands, and range lands. The strength of association between roughness and runoff and infiltration has been weak as shown with correlation analysis. The purpose of this study was to determine relationships of roughness on the contour to roughness perpendicular to the contour as related to infiltration rates and sediment production on range lands. Roughness up and down slopes (vertical) gave a higher correlation than roughness along the contour (horizontal). Adding or subtracting the vertical and horizontal roughness did not increase correlation values. Highest correlation values resulted from entering vertical and horizontal roughness values into a multiple regression equation.
