Tools for Managing Army Training Lands
Army land managers and planners are responsible for managing large, diverse parcels of training land for sustained use. The highly variable but often destructive training requires a systematic...
Chaparral Watershed Management: A Systems Approach
The predicted environmental and economic effects of partial chaparral conversion for increased water yield on an experimental watershed in the Prescott National Forest, Arizona, are examined...
Mass. Municipal Watershed Management?Case Study
Most of the estimated 200,000 acres of municipally-owned watershed land in Massachusetts currently suffers from a lack of wise, multiple-use forest management which has resulted in lost...
An Annual Water Balance for a Surface Mining Overburden Waste Embankment
The embankment contained a volume of 257 thousand cubic yards and resulted from a phosphate surface mining operation in southeastern Idaho. The elevation of the embankment is about 7500...
Simulation of Hillslope Hydrologic Response to Snowmelt in Southwestern Idaho
A two-dimensional, variably saturated porous media flow model was applied to vertical hillslope cross section on a first order study basin in southwestern Idaho. The dominant source of...
Modeling Streamflow Response from Minnesota Peatlands
A deterministic, continuous simulation model was developed to predict the effects of peatland development on streamflow. The Peatland Hydrologic Impact Model is largely physically based...
Landslide Hazard Rating for the Oregon Coast Range
The landslide hazard rating system for shallow soils on steep terrain over hard sandstone has three components: ground water response to precipitation, soil shear strength (including root...
Synthetic Unit Hydrographs for Ozark Watersheds
Few concepts in modern hydrology have been more widely used and abused than unit hydrograph theory. Nevertheless, during the years since its introduction in 1932 as an extension of the...
Predicting Forest Snow Water Equivalent
In California, the snowpack of the Sierra Nevada provides more than one-third of the state's water needs. Regression models used to forecast this supply do not include measurement...
Soil Movement and Surface Roughness on Wyoming Rangelands
Soil movement and surface roughness parameters were evaluated as a function of response to livestock grazing and semiarid shrub control treatments. Repeated elevation measurements of erosion...
Erosion, Productivity and Rangeland Watershed Planning
The Bureau of Land Management is responsible for the management of over 160 million acres of rangeland in the western United States. The principal uses of these rangelands are the grazing...
A Methodology of Assessing Nonpoint Source Pollution from Agricultural Watersheds
Appraisals of water quality impacts induced by applying watershed management practices are difficult due to many factors. Lack of existing research data base, the diffusive characteristics...
Modeling Off-Site Impacts
The off-site impacts of a flood water control program were evaluated by applying the SWRRB (Simulation of Water Resources on Rural Basins) model to a treated basin, primarily agricultural,...
A Giardia Source Investigation in a National Forest Municipal Supply Watershed
For nearly 100 years, the City of Missoula, Montana, obtained most of its municipal water from a surface water supply, Rattlesnake Creek. The Rattlesnake watershed lies within the Lolo...
Prediction of Nutrient and Heavy Metal Transport Capacities of Suspended Sediment in the Southwestern United States
SEDCON, a computerized prediction technique (using forest type and geology as inputs) has been developed to estimate the impacts of land management practices on physical and chemical characteristics...
Cyanide Heap Leaching Problems at Elk City, Idaho
A cyanide heap leaching operation for gold recovery was started in 1983 above the water intake for the community of Elk City in north central Idaho which turned into a problem during the...
Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
Snow Management at Ski Areas: Hydrologic Effects
Several types of snow management are practiced at downhill ski areas. Each of these activities has a variety of hydrologic consequences. The extent to which these management practices...
Closed Negotiations?Out with the Poker Players
The paper describes the closed negotiation process employed by one owner/client, the U. S. Army Corps of Engineers, in procuring firm, fixed price design service contracts. Although not...
Seepage Control at Cochiti Dam, New Mexico
Significant design data, design assumptions and computations, and performance of the seepage control features provided at Cochiti Dam are summarized in this paper. The dam is a rolled...
