This book was released on 1977 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: A system of intensively monitored micro-watersheds was constructed to demonstrate the effects of several specific soil surface manipulation treatments on control of runoff, chemistry of runoff, soil water flow, aquifer characteristics and vegetation establishment at five active coal strip mine areas within th etri-state region of Montana, North Dakota and Wyoming. Surface treatments were chiseling and gouging with and without topsoiling practices, and dozer basins with topsoiling. Without exception, topsoiled watersheds underwent less runoff than similar nontopsoiled watersheds. The total amount (depth) of surface urnoff at the Montana and North Dakota Demonstrations was 1.63 cm for topsoil-dozer basins, 2.32 cm for topsoil-gouged, 4.76 cm for topsoil-chiseled, 13.74 cm for nontopsoil-gouged, and 16.70 cm for nontopsoil-chiseled. Quantities of eroded soil material per treatment watershed resulting in gullies at the Montana Demonstration Areas were 2.7 m^3 for topsoil-dozer basins, 8.1 m^3 for topsoil-gouged, 23.7 m^3 for nontopsoil-gouged, 26.5 m^3 for topsoil-chiseled, and 43.1 m^3 for nontopsoil-chiseled. Thus the fundamental principles of less runoff - less erosion was substantiated on these spoil watersheds. The in situ hydrologic balance of the spoil biosphere was determined using weighing lysimeters and neutron probe techniques. Deep percolation characteristics were measured during precipitation periods. Most watersheds eventually lost this deep percolated water through the evapotranspiration process measured on a hydrologic year basis. A minority of watersheds underwent a net loss of 10 to 20 cm of water as deep percolation for the hydrologic year. Levels of NO3-N, Mg, Ca, soluble salts and most trace elements were found in low concentrations in watershed runoff water. Exceptions were Mn and Fe, where concentrations in runoff waters at all Demonstrations often exceeded federal standards for drinking water. Occasional samples contained Cd, Pb and PO4-P levels which exceeded desirable standards. Surface spoil hydrology and aquifer characteristics interrelationships are discussed, and the aquifer chemical quality presented. Manganese was the only trace element in the ground water which consistently exceeded federal standards for human consumption. A comparison of ground-water quality amound the Demonstration Areas indicates that the highest concentrations for most of the observed parameters were in the developing spoils aquifer at the the North Dakota site. This interim report is submitted in partial fulfillment of Contract No. R-803079-01-0 by the Montana Agricultural Experiment Station under the sponsorship of the U.S. Environmental Protection Agency. This report concentrates most directly on data collected during the period May, 1974 to May, 1976. Work is expected to be completed in September, 1978.
