Numerical modeling of subsurface radioactive solute transport from waste seepage ponds at the Idaho National Engineering Laboratory
John B. Robertson
1976, Open-File Report 76-717
Aqueous chemical and low-level radioactive effluents have been disposed to seepage ponds since 1952 at the Idaho National Engineering Laboratory. The solutions percolate toward the Snake River Plain aquifer (135 m below) through interlayered basalts and unconsolidated sediments and an extensive zone of ground water perched on a sedimentary layer...

History of dredging and filling of lagoons in the San Juan area, Puerto Rico
S. R. Ellis
1976, Water-Resources Investigations Report 76-38
Laguna La Torrecilla, Laguna de Pinones, Laguna San Jose, and Laguna del Condado, in the San Juan, Puerto Rico area, are located within a metropolitan area of more than 1 million people. Bathymetric maps made during the study, in 1973, showed that Lagunas La Torrecilla, San Jose, and del Condado...
Simulation procedure for modeling transient water table and artesian stress and response
J.E. Reed, M. S. Bedinger, J. E. Terry
1976, Open-File Report 76-792
The series of computer programs described in this report were designed specifically to model the ground-water regime in sufficient detail to determine the effects of the imposition of various types of stress upon the system, and to display the results in a convenient manner during calibration and when presenting projected...

A technique for estimating the time of travel of water in Indiana streams
Stephen E. Eikenberry, Leroy G. Davis
1976, Water-Resources Investigations Report 76-9
Estimates of the traveltime of waterborne particles in streams is important for pollution studies and in the event of spills of contaminants. This report provides data for the 16 Indiana streams on which time-of-travel information has been obtained and a means for estimating the velocity of any naturally flowing stream...

Waterlogging in an alluvial aquifer near Lake Minnequa, Pueblo, Colorado
Patrick J. Emmons
1976, Water-Resources Investigations Report 76-53
The Lake Minnequa area, located immediately south of the Arkansas River near Pueblo, Colo., is mantled with as much as 46 feet (14 meters) of alluvium covering bedrock of Pierre Shale and Niobrara Formation. Surface water enters the area by the Minnequa Canal and the St. Charles Flood Ditch. The...

Statistical analysis of water-level, springflow, and streamflow data for the Edwards Aquifer in south-central Texas
Celso Puente
1976, Open-File Report 76-393
Water-level, springflow, and streamflow data were used to develop simple and multiple linear-regression equations for use in estimating water levels in wells and the flow of three major springs in the Edwards aquifer in the eastern San Antonio area. The equations provide daily, monthly, and annual estimates that compare very...
Stability of highwalls in surface coal mines, western Powder Ridge Basin, Wyoming and Montana
Fitzhugh T. Lee, William K. Smith, William Z. Savage
1976, Open-File Report 76-846
Preliminary results from the first part of a two-part investigation of the stability of highwalls in open-pit coal mines in the Fort Union Formation of the western Powder River Basin of Wyoming and Montana indicate that these highwalls are subject to time-dependent deformation. Field investigations and laboratory physical-properties tests of...

Man has altered the original south Florida ecosystem to a new three-part ecosystem which incorporates an agricultural component, an urban component, and a component of the original ecosystem that is largely unchanged but still has been affected by man. These components are interrelated through the flow of energy and material....
