“…These watersheds are affected by one or more climatically different seasons: frontal rainstorms and snowmelt in the winter and spring, and spotty intensive thunderstorms in the summer. The combination of lithology, catchment area, and rainfall and runoff regimes render these basins highly productive in sediment yield and suspended matter concentration during the summer, while less affected by erosion and transport during the winter (as is clearly demonstrated by the Paria River; data from Iorns, Hembree and Oakland (1965). U.S. Geological Survey Water Supply Paper 1995).…”

SUMMARYSediment transport for five small watersheds in arid southern Israel, eroded into shales, chalks, anhydrites and alluvium is studied. Analysis includes data from three large watersheds in the southern United States. Results indicate that floodwater heavily laden with suspended load (10-60 per cent, by weight) is characteristic of watersheds cut in erodible materials. No correlation was found between environmental characteristics such as lithology, catchment area, angle of slope or rainfall intensity and suspended-sediment concentration or texture. The carrying capacity for sands, derived both from hillslopes and channel alluvium is greatly increased by high suspended silt concentratlon, the trend being R cc C;2'5 (where R = ratio, % fines/% sand; C, = suspended load concentration, per cent by weight). The high concentration of fine sediment effectively causes more sand transport than would normally occur. This is also true for transport of coarser clastics; higher velocities, typical of highly concentrated silt suspensions, increased competence for transporting pebbles and boulders. The action of a large variety of processes (splash, wash, rilling, gullying, sliding, mudflow) combine with low infiltration and high erodibility to render every rainstorm erosionally effective, and high concentrations of washload increase both the capacity and competence of coarse clastic transport. Whole basins are thus subjected to high rates of denudation (2-10 mm/yr).

“…Again, these sediment concentrations are 38 percent greater for the Yampa River and 61 percent greater for the Little Snake River than those estimated by lorns, Hembree, and Oakland (1965). Although the average-annual suspended-sediment concentration in the Little Snake River is an order of magnitude greater than in the Yampa River, the total sediment load from the Yampa River subbasin is about 3 to 4 times greater, due to the relatively lower flow from the Little Snake River subbasin.…”

“…Based on analysis of these records, the estimated mean annual suspended-sediment load from the basin is about 2.0 million tons (1.8 million t), which is 11 percent higher than that estimated by lorns, Hembree, and Oakland (1965). The difference may be accounted for largely by the inclusion of bedload estimates in Andrews (1978) computations.…”

Expanded coal production and conversion in the Yampa River basin, Colorado and Wyoming, may have substantial impacts on water resources, environmental amenities, and socioeconomic conditions.Preliminary results of a 3-year basin assessment by the U.S. Geological Survey are given for evaluation of surface-and ground-water resources using available data, modeling analysis of waste-load capacity of a Yampa River reach affected by municipal wastewater-treatment plant effluents, and semiquantitative descriptions of ambient air and water-quality conditions. Aspects discussed are possible constraints on proposed development due to basin compacts and laws regulating water resources, possible change; in environmental-control regulations, and policies on energy-resource leasing and land use that will influence regional economic development.

DescriptorsWater resources, Regional development, Planning, Energy conversion, Coal-mine wastes, Environmental effects, Water-supply decision making, Water quality, Systems analysis, Water rights, Water demand, River-basin development, Public lands, Land use, Colorado, Wyoming, Data collection A major concern of the American public is the enhancement and protection of the environment at minimal social costs, particularly with respect to development and utilization of the Nation's energy resources. The substantial investments made over recent years to protect and to improve air and water quality are being evaluated critically for effectiveness and social desirability. A review of existing and pending legislation which establishes acceptable national goals for environmental protection (including air-and water-quality standards, and land-use planning) is being conducted with the intent of setting more realistic goals in response to changing policies on economic development and energy consumption.The Yampa River basin assessment is one of a series of multidisciplinary studies supported by the U.S. Geological Survey. Each study has considered unique circumstances regarding the physical setting and forms of economic development affecting the environment. In the case of the Yampa River basin, coal resources, population growth, limited water availability, and associated economic development pose as potential problems affecting existing conditions and lifestyle in the region. These studies will help to determine the types and forms of hydrologic, geologic, and other information useful to decisionmaking administrators in their analyses of policies affecting development and use of natural resources.Decisions affecting energy-resource development need to consider the environmental and economic impacts of such development. Expanded energyresource development will lead to increased generation and discharge of residual waste materials to the land, surface and ground waters, and the air. Through modification or treatment, some residuals may be converted to commercial products of economic value. Discharged residuals generally will have an impact on environmental qu...
