Seasonal and semi-permanent wetlands in eastern South Dakota were surveyed in 1995 and 1996 to identify habitat characteristics influencing wetland use by Canada geese (Branta canadensis maxima). Position of a wetland within the landscape and its area were important landscape-scale features influencing wetland use by geese. Our delineation of potential...

1997, Environmental Science & Technology (31) 3341-3347
The chemical interactions of hydrophobic organic contaminants (HOCs) with soils and sediments (geosorbents) may result in strong binding and slow subsequent release rates that significantly affect remediation rates and endpoints. The underlying physical and chemical phenomena potentially responsible for this apparent sequestration of HOCs by geosorbents are not well understood....

1997, Water-Resources Investigations Report 96-4315
Washout and recolonization of macroinvertebrates and algae associated with a spring and summer storm were measured at three sites in Ohio's Big Darby Creek Basin. Related factors, such as streamflow magnitude, shear stress, and streamed disturbance were considered when interpreting observed changes in densities and community structure of macroinvertebrates and...

1997, Water-Resources Investigations Report 96-4299
The 1993 measured winter snow, maximum winter snow, net, and annual balances in the Gulkana Glacier basin were evaluated on the basis of meteorological, hydrological, and glaciological data measured in the basin and are reported herein. Averaged over the glacier, the measured winter snow balance was 0.81 meter on March...

Geohydrology and water quality of Marine Corps Logistics Base, Nebo and Yermo annexes, near Barstow, California
Jill N. Densmore, Brett F. Cox, Steven M. Crawford
1997, Water-Resources Investigations Report 96-4301
Because ground water is the only dependable source of water in the Barstow area, a thorough understanding of the relationship between the geology and hydrology of this area is needed to make informed ground-water management andremediation decisions. This report summarizes geologic and hydrologic studies done during 1992-95 at the Marine...
Use of isotopic data to evaluate recharge and geologic controls on the movement of ground water in Las Posas Valley, Ventura County, California
John A. Izbicki, Peter Martin
1997, Water-Resources Investigations Report 97-4035
Injection, storage, and recovery of imported water is planned for aquifers underlying Las Posas Valley. To evaluate sources of ground-water recharge and the age of the water (time since recharge), and to identify barriers to ground-water flow prior to the injection of imported water, samples from wells and surface sources...
Method for rapid estimation of scour at highway bridges based on limited site data
S.R. Holnbeck, Charles Parrett
1997, Water-Resources Investigations Report 96-4310
Limited site data were used to develop a method for rapid estimation of scour at highway bridges. The estimates can be obtained in a matter of hours rather than several days as required by more-detailed methods. Such a method is important because scour assessments are needed to identify scour-critical...
Ground-water development and the effects on ground-water levels and water quality in the town of Atherton, San Mateo County, California
Loren F. Metzger, John L. Fio
1997, Water-Resources Investigations Report 97-4033
The installation of at least 100 residential wells in the town of Atherton, California, during the 198792 drought has raised concerns about the increased potential for land subsidence and salt water intrusion. Data were collected and monitor ing networks were established to assess current processes and to monitor future conditions...
