Ground-water flow beneath levee 35A from conservation area 2B, Broward County, Florida
Leo J. Swayze
1988, Water-Resources Investigations Report 87-4280
Conservation Area 2B is an area of recharge for the surficial aquifer system in Broward County. Water stored in the conservation area provides the hydraulic potential for downward flow to the high permeability zone of the Biscayne aquifer. A 5.64 ft head differential (average for the period of record) between...
Water withdrawals, use, and trends in Florida, 1985
Richard L. Marella
1988, Water-Resources Investigations Report 88-4103
Total water withdrawn for use in Florida for 1985, in million gal/day, was 17,057 of which 6,259, or nearly 37%, was freshwater and 10,798 was saline. The majority of freshwater withdrawn was groundwater (64%) and the majority of saline water withdrawn was surface water (99%). Thermoelectric power generation accounted for...
Effects of two stormwater management methods on the quality of water in the upper Biscayne aquifer at two commercial areas in Dade County, Florida
Donald J. McKenzie, G. A. Irwin
1988, Water-Resources Investigations Report 88-4069
This study is part of a continued effort to assess the effects of urban stormwater recharge on the water quality of the Biscayne aquifer in southeast Florida. In this report, the water-quality effects on shallow ground water resulting from stormwater disposal by exfiltration trench and grassy swale were investigated at...

Assessment of the role of bottomland hardwoods in sediment and erosion control
A. Molinas, Gregor T. Auble, C.A. Segelquist, Lee S. Ischinger
1988, Report
Drainage and clearing of bottomland hardwoods have long been recognized by the U.S. Environmental Protection Agency (EPA) and the U.S. Fish and Wildlife Service (Service) as important impacts of Federal water projects in the lower Mississippi River Valley. More recently, the water quality impacts of such projects (e.g., increases in...

Numerical analysis of Landsat Thematic Mapper images of Antarctica
Olav Orheim, Baerbel K. Lucchitta
1988, Annals of Glaciology (11) 109-120
Landsat-5 Thematic Mapper (TM) data from Dronning [Queen] Maud Land, Antarctica, have been analysed to provide insights into physical properties of the ice sheet. Brightness (at-satellite) temperatures calculated from digital numbers of the thermal band (TM band 6), using state-of-the-art equations and constants (Markham and Barker 1986), are...

The Mount Mazama climactic eruption (6900 BP) and resulting convulsive sedimentation on the continent, ocean basin, and Crater Lake caldera floor
C. Hans Nelson, Paul R. Carlson, Charles R. Bacon
1988, Book chapter, Sedimentologic consequences of convulsive geologic events
The climactic eruption of Mount Mazama and the resulting sedimentation may have been the most significant convulsive sedimentary event in North America during Holocene time. A collapse caldera 1,200 m deep and 10 km in diameter was formed in Mount Mazama, and its floor was covered by hundreds of meters...

Mg/Mn partitioning as a test for equilibrium between coexisting Fe-Ti oxides
Charles R. Bacon, M.M. Hirschmann
1988, American Mineralogist (73) 57-61
Partitioning of Mg and Mn between titanomagnetite and ferrian ilmenite of volcanic rocks provides a test for equilibrium between coexisting phases. A plot of log(Mg/Mn)-, vs. log(Mg/Mn),, for 213 homogeneous oxide pairs from volcanic rocks yields a straight line over more than two orders of magnitude variation in Mg/Mn. Analyses...

Western state instream flow programs: a comparative assessment
Matthew J. McKinney, Jonathan G. Taylor
1988, Report, Instream Flow Information Paper
During their early history, Western States water rights laws were primarily means for facilitating and regulating water diversions for offstream, consumptive use. More recently, a countervailing concern for instream values such as fish and wildlife habitat, recreation, aesthetic values, and water quality has emerged in the legislative and administrative handling...

My purpose here is to review historic changes in the major fish resources of the five Great Lakes, and to identify the cause or causes for those changes. In some instances it will be clear that intensive fishing was the primary cause of change; in other instances it will be...

Responses of aquatic and streamside amphibians to timber harvest: a review
R. Bruce Bury, Paul Stephen Corn
1988, Book chapter, Streamside management: riparian wildlife and forestry interactions
Stream-dwelling amphibians, which can be the dominant vertebrates of small streams in forests of the Pacific Northwest, are prototypic riparian or ganisms. Larvae of several species are totally aquatic, while adults use the terrestrial streamside (riparian) habitat to varying degrees. Impacts of timber harvest vary among species, physical habitats, and...
