Patterns and sources of fecal coliform bacteria in three streams in Virginia, 1999-2000
Kenneth Hyer, Douglas Moyer
2003, Water-Resources Investigations Report 2003-4115
Surface-water impairment by fecal coliform bacteria is a water-quality issue of national scope and importance. In Virginia, more than 175 stream segments are on the Commonwealth's 1998 303(d) list of impaired waters because of elevated concentrations of fecal coliform bacteria. These fecal coliform-impaired stream segments require the development of total maximum daily load...

An overview of coastal land loss with emphasis on the southeastern United States
Robert A. Morton
2003, Open-File Report 2003-337
This report represents a general overview of the primary causes and consequences of coastal land loss. Most of the examples and references are from states bordering the Gulf of Mexico and the Atlantic Ocean where the largest magnitudes and highest rates of coastal land losses in the United States are...

Southeastern U.S. vegetation response to ENSO Events (1989–1999)
Albert J. Peters, Elizabeth Walter-Shea
2003, Climatic Change (60) 175-188
El Niño/Southern Oscillation (ENSO) is considered one of the most powerful forces driving anomalous global weather patterns. Large-scale seasonal precipitation and temperature changes influenced by ENSO have been examined in many areas of the world. The southeastern United States is one of the regions affected by ENSO events. In this...

Pesticides in surface water in the lower Illinois River basin, 1996-98
Robin B. King
2003, Water-Resources Investigations Report 2002-4097
Surface-water quality samples were collected from April 1996 to September 1998 from eight locations in the Lower Illinois River Basin, a study unit of the U.S. Geological Survey?s National Water-Quality Assessment program. The study area is approximately 15,600 square miles and encompasses most of central and western Illinois. The dominant...
Research observation: Hydrolyzable and condensed tannins in plants of northwest Spain forests
M. P. Gonzalez-Hernandez, J. Karchesy, E. E. Starkey
2003, Journal of Range Management (56) 461-465
Tannins are secondary metabolites that may influence feeding by mammals on plants. We analyzed hydrolyzable and condensed tannins in 30 plant species consumed by livestock and deer, as a preliminary attempt to study their possible implications on browsing and grazing in forest ecosystems. Heathers (Ericaceae) and plants of the Rose (Rosaceae) family had tannins, while forbs, grasses and shrubs other than the heathers did not show...
Simulation of streamflow and estimation of streamflow constituent loads in the San Antonio River watershed, Bexar County, Texas, 1997-2001
Darwin J. Ockerman, Kenna C. McNamara
2003, Water-Resources Investigations Report 2003-4030
The U.S. Geological Survey developed watershed models (Hydrological Simulation Program—FORTRAN) to simulate streamflow and estimate streamflow constituent loads from five basins that compose the San Antonio River watershed in Bexar County, Texas. Rainfall and streamflow data collected during 1997–2001 were used to calibrate and test the model. The model was...
Water-quality assessment of the eastern Iowa Basins: Selected pesticides and pesticide degradates in streams, 1996-98
Douglas J. Schnoebelen, Stephen J. Kalkhoff, Kent Becher, E.M. Thurman
2003, Water-Resources Investigations Report 2003-4075
Water samples were collected in streams of the Eastern Iowa Basins study unit from 1996 to 1998 as part of the U.S. Geological Survey’s National Water-Quality Assessment (NAWQA) Program. More than 350 samples were collected to document the occurrence, distribution, and transport of pesticides and pesticide degradates. The Eastern Iowa...
Urban land-cover change detection through sub-pixel imperviousness mapping using remotely sensed data
Limin Yang, George Z. Xian, Jacqueline M. Klaver, Brian Deal
2003, Photogrammetric Engineering and Remote Sensing (69) 1003-1010
We developed a Sub-pixel Imperviousness Change Detection (SICD) approach to detect urban land-cover changes using Landsat and high-resolution imagery. The sub-pixel percent imperviousness was mapped for two dates (09 March 1993 and 11 March 2001) over western Georgia using a regression tree algorithm. The accuracy of the predicted imperviousness was...

Tracing reclaimed water in the Menifee, Winchester, and Perris-South ground-water subbasins, Riverside County, California
Charles A. Kaehler, Kenneth Belitz
2003, Water-Resources Investigations Report 2003-4039
As a component in the management of water resources in the Menifee, Winchester, and Perris-South subbasins in Riverside County, California, ponds are operated by the Eastern Municipal Water District for the temporary storage of reclaimed water that is produced by several regional water-reclamation facilities. A primary goal of this study...

Using sensitivity analysis in model calibration efforts
Claire R. Tiedeman, Mary C. Hill
2003, Book chapter, Proceedings of the International Workshop on Uncertainty, Sensitivity, and Parameter Estimation for Multimedia Environmental Modeling
In models of natural and engineered systems, sensitivity analysis can be used to assess relations among system state observations, model parameters, and model predictions. The model itself links these three entities, and model sensitivities can be used to quantify the links. Sensitivities are defined as the derivatives of simulated quantities...

Determination of water depth with high-resolution satellite imagery over variable bottom types
Richard P. Stumpf, Kristine Holderied, Mark Sinclair
2003, Limnology and Oceanography (48) 547-606
A standard algorithm for determining depth in clear water from passive sensors exists; but it requires tuning of five parameters and does not retrieve depths where the bottom has an extremely low albedo. To address these issues, we developed an empirical solution using a ratio of reflectances that has only...
