An autonomous, electromagnetic seepage meter to study coastal groundwater/surface-water exchange
Peter W. Swarzenski, Matt Charette, Christian D. Langevin
2004, Open-File Report 2004-1369
The bi-directional exchange of groundwater with coastal surface waters may influence not only coastal-water and geochemical budgets, but may also impact and direct coastal ecosystem change. For example, the widespread discharge of nutrient-enriched submarine groundwater into an estuary or lagoon may contribute directly to the onset and duration of eutrophication,...

2004, Water-Resources Investigations Report 2003-4312
Observed ground-water-level declines from 1991 to 2003 in northern Monroe County, Michigan, are consistent with increased ground-water demands in the region. In 1991, the estimated ground-water use in the county was 20 million gallons per day, and 80 percent of this total was from quarry dewatering. In 2001, the estimated...

David T. Soong, Audrey L. Ishii, Jennifer B. Sharpe, Charles F. Avery
2004, Scientific Investigations Report 2004-5103
Flood-peak discharge magnitudes and frequencies at streamflow-gaging sites were developed with the annual maximum series (AMS) and the partial duration series (PDS) in this study. Regional equations for both flood series were developed for estimating flood-peak discharge magnitudes at specified recurrence intervals of rural Illinois streams. The regional equations are techniques for estimating...

Tannins and terpenoids as major precursors of Suwannee River fulvic acid
Jerry A. Leenheer, Colleen E. Rostad
2004, Scientific Investigations Report 2004-5276
Suwannee River fulvic acid (SRFA) was fractionated into 7 fractions by normal-phase chromatography on silica gel followed by reverse-phase fractionation on XAD-8 resin that produced 18 subfractions. Selected major subfractions were characterized by 13C-nuclear magnetic resonance (NMR), infrared spectrometry, and elemental analyses. 13C-NMR spectra of the subfractions were more indicative...
A method for simulating transient ground-water recharge in deep water-table settings in central Florida by using a simple water-balance/transfer-function model
Andrew M. O’Reilly
2004, Scientific Investigations Report 2004-5195
A relatively simple method is needed that provides estimates of transient ground-water recharge in deep water-table settings that can be incorporated into other hydrologic models. Deep water-table settings are areas where the water table is below the reach of plant roots and virtually all water that is not lost to...

William J. Rose, Dale M. Robertson, Elizabeth A. Mergener
2004, Scientific Investigations Report 2004-5141
Pike Lake is a 459-acre, mesotrophic to eutrophic dimictic lake in southeastern Wisconsin. Because of concern over degrading water quality in the lake associated with further development in its watershed, a study was conducted by the U.S. Geological Survey from 1998 to 2000 to describe the water quality and hydrology...

B. R. Lewelling
2004, Scientific Investigations Report 2004-5133
Riverine and palustrine wetlands are a major ecological component of river basins in west-central Florida. Healthy wetlands are dependent, in part, upon the frequency and duration of periodic flooding or inundation. This report assesses the extent, area, depth, frequency, and duration of periodic flooding and the effects of potential surface-water...
