2010, Techniques and Methods 3-A8
The techniques and standards for making discharge measurements at streamflow gaging stations are described in this publication. The vertical axis rotating-element current meter, principally the Price current meter, has been traditionally used for most measurements of discharge; however, advancements in acoustic technology have led to important developments in the use...
Stage measurement at gaging stations
Vernon B. Sauer, D. Phil Turnipseed
2010, Techniques and Methods 3-A7
Stream and reservoir stage are critical parameters in the computation of stream discharge and reservoir volume, respectively. In addition, a record of stream stage is useful in the design of structures that may be affected by stream elevation, as well as for the planning for various uses of flood plains....

A new parameterization for estimating co‐occurrence of interacting species
J. Hardin Waddle, Robert M. Dorazio, Susan C. Walls, Kenneth G. Rice, Jeff Beauchamp, Melinda J. Schuman, Frank J. Mazzotti
2010, Ecological Applications (20) 1467-1475
Models currently used to estimate patterns of species co‐occurrence while accounting for errors in detection of species can be difficult to fit when the effects of covariates on species occurrence probabilities are included. The source of the estimation problems is the particular parameterization used to specify species co‐occurrence probability. We...

2010, Conference Paper, Proceedings of the Joint Federal Interagency Conference 2010: Hydrology and Sedimentation for a Changing Future: Existing and Emerging Issues: Las Vegas, NV, June 27-July 1, 2010
The importance of dependable, long-term water supplies, coupled with the need to quantify rates of capacity loss of the Nation’s re servoirs due to sediment deposition, were the most compelling reasons for developing the REServoir- SEDimentation survey information (RESSED) database and website. Created under the auspices of the Advisory Committee...
Computing time-series suspended-sediment concentrations and loads from in-stream turbidity-sensor and streamflow data
Patrick P. Rasmussen, John R. Gray, G. Doug Glysson, Andrew C. Ziegler
2010, Conference Paper, Proceedings of the Joint Federal Interagency Conference 2010: Hydrology and Sedimentation for a Changing Future: Existing and Emerging Issues: Las Vegas, NV, June 27-July 1, 2010
Over the last decade, use of a method for computing suspended-sediment concentration and loads using turbidity sensors—primarily nephelometry, but also optical backscatter—has proliferated. Because an in- itu turbidity sensor is capa le of measuring turbidity instantaneously, a turbidity time series can be recorded and related directly to time-varying suspended-sediment concentrations....

2010, Journal of Geophysical Research B: Solid Earth (115)
We investigated the frictional sliding behavior of simulated quartz-clay gouges under stress conditions relevant to seismogenic depths. Conventional triaxial compression tests were conducted at 40 MPa effective normal stress on saturated saw cut samples containing binary and ternary mixtures of quartz, montmorillonite, and illite. In all cases, frictional strengths of...

Summer stream water temperature models for Great Lakes streams: New York
James E. McKenna, Ryan S. Butryn, Richard P. McDonald
2010, Transactions of the American Fisheries Society (139) 1399-1414
Temperature is one of the most important environmental influences on aquatic organisms. It is a primary driver of physiological rates and many abiotic processes. However, despite extensive research and measurements, synoptic estimates of water temperature are not available for most regions, limiting our ability to make systemwide and large-scale assessments...

James H. Roberts, Nathaniel P. Hitt
2010, Conference Paper, Community ecology of stream fishes : concepts, approaches, and techniques; American Fisheries Symposium 73
Five conceptual models of longitudinal fish community organization in streams were examined: (1) niche diversity model (NDM), (2) stream continuum model (SCM), (3) immigrant accessibility model (IAM), (4) environmental stability model (ESM), and (5) adventitious stream model (ASM). We used differences among models in their predictions about temporal species turnover,...
