Alluvial soil constitute the largest soil group in India, constituting 80 % of the total land surface. 4. Hydrological soil group 'D'with slow rate of infiltration covers more than half of this area. 5. The most prevalent hydrologic soil groups are C ( 80 percent ) and B ( 20 percent ). 6. Technosols are a new form of soil group in the World Reference Base for Soil Resources ( WRB ). 7. The dominant hydrologic soil groups in the watershed include C ( 80 percent ) and B ( 20 percent ). 8. References, such as from USDA indicate the runoff curve numbers for characteristic land cover descriptions and a hydrologic soil group . 9. The runoff curve number is based on the area's hydrologic soil group , land use, treatment and hydrologic condition. 10. The watershed's soils are in mostly the hydrologic soil groups B and C . However, the hydrological soil group D is also present.
