Water quality in Rhode River at Smithsonian Institution Pier near Annapolis, Maryland, January 1976 through December 1978
Robert L. Cory, P.V. Dresler
1980, Water-Resources Investigations Report 79-109
Water temperature, salinity, turbidity, dissolved oxygen, pH, and water level data were continuously monitored and recorded from the Smithsonian Institution pier near Annapolis, Md., from January 1976 through December 1978. Daily maximum and minimum values are tabulated and summarized, and monthly averages and extremes are presented. Water temperature ranged from...
Extension of transient-flow model of the Sacramento River at Sacramento, California
Richard N. Oltmann
1980, Water-Resources Investigations Report 80-30
The multiple-reach method-of-characteristics flow-simulaltion model that was successfully applied in 1976 to a 10.8-mile tide-affected reach of the Sacramento River, in California, from Sacramento to Freeport has been extended 10.5 miles farther downstream of Hood. The model reach was extended to improve the quality of the model 's output during...
An annotated bibliography of devices developed for direct measurement of seepage
Mark R. Carr, Thomas C. Winter
1980, Open-File Report 80-344
The need for information on the interrelationship of groundwater and surface water is causing a growing interest in methods used for direct measurement of seepage to and from surface-water bodies. Instruments developed for measurement of seepage date from about the mid 1940 's largely in response to the need for...
Hydrologic analysis of the proposed Badger-Beaver Creeks artificial-recharge project: Morgan County, Colorado
Alan W. Burns
1980, Water-Resources Investigations Report 80-46
A hydrologic analysis of the proposed Badger-Beaver Creeks artificial-recharge project in Morgan County, Colo., was made with the aid of three digital computer models: A canal-distribution model, a ground-water flow model, and a stream-aquifer model. Statistical summaries of probable diversions from the South Platte River based on a 27-year period...
Technique for estimating the magnitude and frequency of floods in the Houston, Texas, Metropolitan Area
Fred Liscum, B.C. Massey
1980, Water-Resources Investigations Report 80-17
A technique for estimating the magnitude and frequency of floods in the Houston, Texas, metropolitan area was developed by use of a multiple-regression flood-frequency analysis of flow data from unregulated streams in the area. A regression model, relating flood-peak discharge to concurrent rainfall and antecedent soil moisture conditions, was used...
Aeromagnetic map of Montana
Isidore Zietz, Francis P. Gilbert, Stephen L. Snyder

Relationships between aerodynamic roughness and land use and land cover in Baltimore, Maryland
F.W. Nicholas, J.E. Lewis Jr.
1980, Professional Paper 1099-C
Urbanization changes the radiative, thermal, hydrologic, and aerodynamic properties of the Earth's surface. Knowledge of these surface characteristics, therefore, is essential to urban climate analysis. Aerodynamic or surface roughness of urban areas is not well documented, however, because of practical constraints in measuring the wind profile in the presence of...
Biological premonitors of earthquakes: A validation study
Leon Spelly Otis, W.H. Kautz
1980, Open-File Report 80-1152
For the greatest ultimate usefulness to society, the two most important facets of earthquake prediction are (1) a fundamental scientific understanding of the earthquake-triggering process and (2) the identification of reliable and measurable premonitors. A possible approach to both of these problem areas, and one that has received almost no...
Potential effects of increased ground-water pumpage on Barka Slough, San Antonio Creek Valley, Santa Barbara County, California
Michael J. Mallory
1980, Water-Resources Investigations Report 80-95
Ground-water use in San Antonio Creek valley is expected to increase significantly as a result of planned extensive agricultural development in the basin. The effects of this additional stress on the ground-water system, particularly on the environmentally sensitive Barka, Slough, are of concern in the basin.Expectations of the developer are...
The influences of land use and land cover on climate; an analysis of the Washington-Baltimore area that couples remote sensing with numerical simulation
R.W. Pease, C.B. Jenner, J.E. Lewis Jr.
1980, Professional Paper 1099-A
The Sun drives the atmospheric heat engine by warming the terrestrial surface which in turn warms the atmosphere above. Climate, therefore, is significantly controlled by complex interaction of energy flows near and at the terrestrial surface. When man alters this delicate energy balance by his use of the land, he...
