Evolution of coarse gravel bed forms: Field measurements at flood stage
Field measurements to investigate the origin and growth of mesoscale gravel bed forms in deep flows were made in the North Fork Toutle River, Washington. Sonar observations of the gravel streambed at a stationary point were recorded during two storm flows in December 1989 and January 1990 with concurrent bed load sampling and continuous velocity measurements. Mean diameter of bed load was about 3

Sensitivity of ground - water recharge estimates to climate variability and change, Columbia Plateau, Washington
The sensitivity of groundwater recharge estimates was investigated for the semiarid Ellensburg basin, located on the Columbia Plateau, Washington, to historic and projected climatic regimes. Recharge was estimated for predevelopment and current (1980s) land use conditions using a daily energy-soil-water balance model. A synthetic daily weather generator was used to simulate lengthy sequences with

Methods of analysis by the U. S. Geological Survey National Water Quality Laboratory-Determination of organonitrogen herbicides in water by solid-phase extraction and capillary-column gas chromatography/mass spectrometry with selected-ion monitoring
A method for the isolation of organonitrogen herbicides from natural
water samples using solid-phase extraction and analysis by capillary-column
gas chromatography/mass spectrometry with selected-ion monitoring is
described. Water samples are filtered to remove suspended particulate matter
and then are pumped through disposable solid-phase extraction cartridges
containing octadecyl-bonded por

Hydrologic research at the Princeton, Minnesota management systems evaluation area
The Management Systems Evaluation Area (MSEA) program is part of a multi-scale, inter-agency initiative to evaluate the effects of agricultural management systems on water quality. The program resulted from the integration of the U.S. Department of Agriculture (USDA) Research Plan for Water Quality and the U.S Geological Survey (USGS) Mid-Continent Herbicide Initiative and is part of the President

Hydrologic data for the Big Spring basin, Clayton County, Iowa, water year 1990
Hydrologic data were collected in the Big Spring basin located in Clayton County, Iowa, during the 1990 water year. The data were collected by the U.S. Geological Survey in cooperation with the Iowa Department of Natural Resources, Geological Survey Bureau, to provide information on variation and movement of agricultural chemicals in the hydrologic cycle in the basin. Precipitation, surface-water,

A modular finite-element model (MODFE) for areal and axisymmetric ground-water-flow problems, Part 2: Derivation of finite-element equations and comparisons with analytical solutions
MODFE, a modular finite-element model for simulating steady- or unsteady-state, area1 or axisymmetric flow of ground water in a heterogeneous anisotropic aquifer is documented in a three-part series of reports. In this report, part 2, the finite-element equations are derived by minimizing a functional of the difference between the true and approximate hydraulic head, which produces equations that

Analytical solutions for one-, two-, and three-dimensional solute transport in ground-water systems with uniform flow
Analytical solutions to the advective-dispersive solute-transport equation are useful in predicting the fate of solutes in ground water. Analytical solutions compiled from available literature or derived by the author are presented for a variety of boundary condition types and solute-source configurations in one-, two-, and three-dimensional systems having uniform ground-water flow. A set of user-

Selected papers in the hydrologic sciences, 1988-92
Selected Papers in the Hydrologic Sciences, a U.S. Geological Survey-managed journal-type publication in the Water-Supply Paper series, is aimed at meeting widespread public and professional needs for results of state-of-the-art broad-based hydrologic studies. The results of these studies are derived from integrated water-resource projects of the Federal research program, Federal-State cooperative
Evaluation of selected methods for determining streamflow during periods of ice effect
Seventeen methods for estimating ice-affected streamflow are evaluated for potential use with the U.S. Geological Survey streamflow-gaging station network. The methods evaluated were identified by written responses from U.S. Geological Survey field offices and by a comprehensive literature search. The methods selected and techniques used for applying the methods are described in this report. The m
