Water resources of northeast Iowa
In 1965 a cooperative investigation with the U.S. Geological Survey produced Water Atlas No. 1 (Twenter and Coble, 1965). It presented information on the occurrence, availability, use, quality, and future demand of water in 10 counties in the central part of the state. Subsequent investigations produced Water Atlases No. 4 (Coble and Roberts, 1971) for southeast Iowa, No. 5 (Cagle and Heinitz, 1

Slope movements triggered by heavy rainfall, November 3–5, 1985, in Virginia and West Virginia, U.S.A.
Study of slope movements triggered by the storm of November 3–5, 1985, in the central Appalachian Mountains, U.S.A., has helped to define the meteorologic conditions leading to slope movements and the relative importance of land cover, bedrock, surficial geology, and geomorphology in slope movement location. This long-duration rainfall at moderate intensities triggered more than 1,000 slope moveme

Accuracy of acoustic velocity metering systems for measurement of low velocity in open channels
Acoustic velocity meter (AVM) accuracy depends on equipment limitations, the accuracy of acoustic-path length and angle determination, and the stability of the mean velocity to acoustic-path velocity relation. Equipment limitations depend on path length and angle, transducer frequency, timing oscillator frequency, and signal-detection scheme. Typically, the velocity error from this source is about

Vegetative changes in a wetland in the vicinity of a well field, Dade County, Florida
Plant communities present in 1978 and 1986 were analyzed at 250 random points on stereoscopic pairs of aerial photographs for four study sites in the vicinity of the Northwest Well Field in Dade County, Florida. Sites NW and NE lie northwest of the well field beyond the cone of depression. Site SW lies in the outer part of the cone, and site SE lies within the cone of depression. Relative frequenc

Hydrological, morphometrical, and biological characteristics of the connecting rivers of the International Great Lakes: a review
The connecting channels of the Great Lakes are large rivers (1, 200-9, 900 m3 • s-1) with limited tributary drainage systems and relatively stable hydrology (about 2:1 ration of maximum to minimum flow). The rivers, from headwaters to outlet, are the St. Marys, St. Clair, Detroit, Niagara, and St. Lawrence. They share several characteristics with certain other large rivers: the fish stocks that hi

Coastal barrier resources system mapping process
The Coastal Barrier Resources Act of 1982 (P.L. 97-348) established the Coastal Barrier Resources System (system), a 452,834 acre system of undeveloped, unprotected coastal barriers along 666 shoreline miles of the Atlantic Ocean and Gulf of Mexico coasts. Within the 186 unites of the Coastal Barrier Resources System, most Federal expenditures that encourage development are prohibited. Section 10

Foods and dietary strategies of prairie-nesting ruddy ducks and redheads
Actively feeding Ruddy Ducks (Oxyura jamaicensis) and Redheads (Aythya americana) were collected from North Dakota wetlands during the 1979-1981 breeding seasons. Foods found within esophagi were analyzed on a wet-weight aggregate percent basis. Male and prelaying and laying female Ruddy Ducks consumed >90% invertebrates, primarily chironomids. Postlaying female Ruddy Ducks consumed 73% invertebra

Flow pattern in regional aquifers and flow relations between the lower Colorado River valley and regional aquifers in six counties of southeastern Texas
The lower Colorado River discussed in this report consists of the 318- river-mile reach from Mansfield Dam near Austin, Texas, to the Gulf of Mexico. The river is underlain directly or indirectly by six regional aquifers the Trinity Group, Edwards, Carrizo-Wilcox, Queen City, Sparta, and Gulf Coast; the Trinity Group aquifer is further subdivided into the lower Trinity, middle Trinity, and upper T

Aquifers in Cretaceous rocks of the central Coastal Plain of North Carolina
Aquifers in rocks of Cretaceous age are the major source of groundwater for public supplies in the central Coastal Plain. These aquifers consist of sand, gravel, and limestone beds of the Peedee, Black Creek, and the upper and lower Cape Fear aquifers, each separated by a confining unit composed of clay and silt beds. The aquifers and confining units (1) rest upon crystalline basement rocks; (2) d

Sediment transport and accretion and the hydrologic environment of Grove Creek near Kenansville, North Carolina
The Grove Creek basin includes an area of about 42 square miles in Duplin County, southeastern North Carolina. This report evaluates sediment transport and sediment-accretion rates in the lowermost 9-mile reach of Grove Creek by using hydrologic, dendrologic, and radioisotopic data collected at seven sites along the study reach.
Hydrologic data indicate two discharge frequencies. In the swampie
