Harvey E. Jobson, Thomas N. Keefer
1979, Professional Paper 1136
A coupled flow-temperature model has been developed and verified for a 27.9-km reach of the Chattahoochee River between Buford Dam and Norcross, Ga. Flow in this reach of the Chattahoochee is continuous but highly regulated by Buford Dam, a flood-control and hydroelectric facility located near Buford, Ga. Calibration and verification...

Anthony J. Gogel
1979, Open-File Report 79-1055
Saline-water inflow from Permian rocks has resulted in the degradation of freshwater systems in several areas of central and south-central Kansas. Solution of evaporite beds has occurred along the eastern edge of the Wellington Formation, chiefly within the Hutchinson Salt Member and associated gypsum units. The solution, caused by leakage...

1979, Open-File Report 79-1651
Core samples from a roll type uranium deposit in Live Oak County, south Texas have been studied and results are reported for Se, Mo, FeS2 and organic-carbon distribution, sulfide mineral petrology, and sulfur isotopic composition of iron-disulfide phases. In addition, sulfur isotopic compositions of dissolved sulfate and sulfide from the...
Water resources of the Marquette Iron Range area, Marquette County, Michigan
N.G. Grannemann
1979, Open-File Report 79-1339
Dependable water supplies are vital to the mining industry in the Marquette Iron Range in Michigan. Development of processes that concentrate and pelletize low-grade iron ore has permitted mining to expand during the past two decades. Water demand has increased both for iron ore concentration processes and for the area...

William J. Todd, C.C. Blackmon, R.G. Rudasill Jr.
1979, Practicing Planner (9) 6-10
Since the adoption of a Regional Development Plan in 1975, the Atlanta Regional Commission has investigated methods for monitoring regional development patterns in a periodic, efficient manner. A promising approach appears to be the use of Landsat satellite data. In cooperation with the Earth Resources Observation Systems (EROS) Data Center,...
A two-dimensional hydrodynamic model of a tidal estuary
Roy A. Walters, Ralph T. Cheng
1979, Advances in Water Resources (2) 177-184
A finite element model is described which is used in the computation of tidal currents in an estuary. This numerical model is patterned after an existing algorithm and has been carefully tested in rectangular and curve-sided channels with constant and variable depth. One of the common uncertainties in this class...

Managing the rippling stream: decisionmaking in natural resource administration
Harvey R. Doerksen, Berton L. Lamb
1979, Journal of the American Water Resources Association (15) 1707-1715
This article addresses the conflict which exists within the water resources decisionmaking arena over the allocation of water for instream uses. The discussion reviews the literature on public administration regarding decisionmaking, and is based on research performed by the authors which synthesizes a model of decisionmaking. This model can be...
Robust estimation of population size when capture probabilities vary among animals
K.P. Burnham, W.S. Overton
1979, Ecology (60) 927-936
A model is given for multiple recapture studies on closed populations which allows capture probabilities to vary among individuals. The capture probability of each individual is assumed to be constant over time. Based on this model we give a nonparametric estimation procedure for population size. The estimator...
Contribution of groundwater modeling to planning
J.E. Moore
1979, Journal of Hydrology (43) 121-128
The consideration of groundwater in water-resource planning frequently has been neglected because many planners believed that groundwater could not be adequately evaluated in terms of availability, quality, cost of development, or effect of development on the surface-water supply. The development of predictive groundwater models now provides the water planner with...

William Normark, D.J.W. Piper, Gordon R. Hess
1979, Sedimentology (26) 749-774
The deep-tow instrument package of Scripps Institution of Oceanography provides a unique opportunity to delineate small-scale features of a size comparable to those features usually described from ancient deep-sea fan deposits. On Navy Fan, the deep-tow side-scanning sonar readily detected steep channel walls and steps and terraces within channels. The...
A parametric generalization of the Hayne estimator for line transect sampling
Kenneth P. Burnham
1979, Biometrics (35) 587-595
The Hayne model for line transect sampling is generalized by using an elliptical (rather than circular) flushing model for animal detection. By assuming the ration of major and minor axes lengths is constant for all animals, a model results which allows estimation of population density based directly upon sighting...
