Analysis of onsite measurements of scour at piers
Existing onsite measurements of local scour at bridge piers were assembled and analyzed to obtain an equation that predicts the expected maximum depth of local scour at a bridge pier. A safety factor is suggested that provides a reasonable margin of error for design purposes.

Applications of satellite telemetry to wildlife research and management in Alaska
Since 1984, the Alaska Fish and Wildlife Research Center, in cooperation with the Alaska Department of Fish and Game and several other agencies, has used the Argos Data Collection and Location System to address wildlife research and management problems in Alaska and other parts of North America. The use of satellite telemetry has overcome some of the logistical problems of working in remote areas

Calibration of water-velocity meters
The U.S. Geological Survey, Department of the Interior, as part of its responsibility to appraise the quantity of water resources in the United States, maintains facilities for the calibration of water-velocity meters at the Gulf Coast Hydroscience Center's Hydraulic Laboratory Facility, NSTL, Mississippi. These meters are used in hydrologic studies by the Geological Survey, U.S. Army Corps of Eng

Determining transit losses for water deliveries by use of stream-aquifer models
Hydrologic modeling of stream-aquifer interaction commonly has been used to quantify transit losses associated with water deliveries, such as those from reservoir storage. This technique requires estimation of model parameters that include stage-discharge relations, channel-storage coefficient, aquifer transmissivity, and aquifer-storage coefficient. Because data to reliably estimate or calibrate

EFFECTS OF METEOROLOGICAL CHANGES ON CONCENTRATIONS OF HELIUM, CARBON DIOXIDE, AND OXYGEN IN SOIL GASES.
Samples were collected from a hollow probe at 0. 75-m depth and from a plastic hemisphere on the ground surface. Soil temperature, air temperature, percent humidity, and barometric pressure were also measured. Soil moisture was measured only indirectly as amount of rain or snowfall. Higher concentrations of CO//2 in both the 0. 75-m and surface samples correlated with higher soil and air temperatu

Effects of the 1982-83 El Niño – Southern Oscillation on Pacific Ocean bird populations
Seabird reproductive success, population size, and movements in the Pacific region responded dramatically to the 1982-83 El Niño – Southern Oscillation (ENSO). At sites within the North and South Pacific Gyres, the onset of seabird responses tracked oceanographic changes related to ENSO; to the north of the gyres, responses were delayed 1 yr. Reproductive failures and high adult mortality were det

Estimation of urban stormwater quality
Two data-based methods for estimating urban stormwater quality have recently been made available - a planning level method developed by the U.S. Environmental Protection Agency (EPA), and a nationwide regression method developed by the U.S. Geological Survey. Each method uses urban stormwater water-quality constituent data collected for the Nationwide Urban Runoff Program (NURP) during 1979-83. Th

Federal microcomputer software for urban hydrology
The purpose of this paper is to describe the development, availability, and general use of selected urban hydrology microcomputer software developed by: U.S. Soil Conservation Service (SCS); U.S. Army Corps of Engineers, Hydrologic Engineering Center (HEC); U.S. Environmental Protection Agency (EPA); and U.S. Geological Survey (USGS). The discussion is limited to software used for design and plann
