Effects Of Stream Channel Improvements On Downstream Floods, Yang H. Huang, Ronald K. Gaynor

KWRRI Research Reports

This report presents a self-calibrating watershed model for predicting the effect of channel improvements on downstream floods. The model is called MOPSET because it is a modified version of OPSET developed several years ago at the University of Kentucky. OPSET is a computerized procedure for determining an optimum set of parameter values by matching synthesized flows with recorded flows. Major modifications include the replacement of the modified Muskingum method of channel routing by a kinematic finite difference method, the division of the watershed into a number of segments, and the inclusion of a storage routing procedure to take care of …

Statistical Models For Precipitation, Z. Govindarajulu, Peter Purdue, Frank Cioch

KWRRI Research Reports

The available data consists of daily rainfall for the past 24 years (1948-1972) for Lexington, Louisville and Paducah. However, for Ashland, the data is available for the period of 40 years (1932-1972). The problem is to find an appropriate family of distributions indexed by a suitable number of parameters that fits the maximum daily rainfall. Further, there might be seasonal variations. The following seasons were considered: (i) Dry Convective season: August 1-0ctober 30; (ii) Early Convective season: May 1-July 31; (iii) Late Convective season: November 1- April 30. After extracting the yearly maximums for each of these seasons (see Appendix …

Final Report - Lake Mead Monitoring Program, James E. Deacon

Publications (WR)

The Lake Mead monitoring program has developed a substantial body of information on the physical, chemical and biological limnology of Lake Mead since 1972. This report summarizes pertinent aspects of that data, with emphasis on studies completed in 1975 -76. It is our continuing hope that the data developed by us will be useful to an ever broader group of users of the water resource represented by Lake Mead. We have been privileged to see our data have a significant influence in some very important water resource decisions over the past four years. There is every reason to expect that …

Distribution Of Carbonate In Surface Sediments Of The Pacific Ocean, W. H. Berger, Charles Adelseck, Larry A. Mayer

Affiliate Scholarship

The distribution of carbonate on the floor of the Pacific has been remapped on the basis of 1313 points from 80 references stored in the World Ocean Sediment Data Bank of Scripps Institution of Oceanography. Percent distribution maps and carbonate versus depth diagrams generally agree with previously published information and reflect the major controlling factors of carbonate sedimentation (depth, hydrography, fertility, and sedimentary processes). While carbonate distributions are of limited use in attempting to construct dissolution profiles, major trends are identifiable. In particular, the degree of lowering of the equatorial calcite compensation depth (CCD) together with an estimate of the …

Control Of Clay Mineral Distribution By Estuarine Circulation, James River Estuary, Virginia, Jean-Pierre Feuillet

OES Theses and Dissertations

A study was performed on the clay minerals of the James River estuary, Virginia, to determine the predominant factors that influence clay mineral distribution in the estuary. The factors of differential settling, flocculation, and diagenesis show minor or no effects on distribution, while estuarine circulation exerts the strongest influence upon the clay mineral distribution.

There are two clay suites in the James River estuary. The upper James River clay suite is a kaolinite, dioctahedral vermiculite, and mixed-layer suite, with kaolinite being the major mineral. The lower Chesapeake Bay clay suite is an illite, chlorite, and montmorillonite suite, with illite being …

Dynamics And Sedimentology Of Inner Middle Ground - Nine Foot Shoal, Chesapeake Bay, Virginia, Mitchell Alan Granat

OES Theses and Dissertations

The historical, hydrodynamic, and sedimentological development of Inner Middle Ground - Nine Foot Shoal indicates that it is presently in quasi-equilibrium with mutually evasive ebb and flood tidal currents. Bathymetric comparisons among six surveys taken during the past 122 years depict development of the shoal from two linear sand bodies to its present double parabolic morphology. Circulation paths are proposed for each survey.

Information from eight current meter stations on and adjacent to Inner Middle Ground - Nine Foot Shoal were used to determine near-surface and near-bottom tidal current asymmetries and directions. The concepts of bathymetrically diverted currents and mutual …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume Iv - The Effects Upon The Benthic Associations, Louise Russert Kraemer

Arkansas Water Resources Center Technical Reports

The huge and increasing volume of dredged materials being moved in and from the bottoms of waterways of the U.S. is probably well known to the reader. Lee and Plumb (1974) distinguish between the 2 forms of dredging: (1) mining the bottom sediments (as in shell dredging), and (2) developing and maintaining navigable waterways. They indicate some 380,000,000 cubic yards are dredged annually in this country; maintenance dredging accounting for about 80,000,000 cy, and new construction for about 300,000,000 cy.* These figures (based on 5 yr. averages) do not include dredging by private companies. Smith (1975) comments: "With federal dredging …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume V - The Effects Upon The Fish Population, Thomas M. Buchanan

Arkansas Water Resources Center Technical Reports

The Arkansas River extends for 1,450 miles from the eastern slopes of the Rocky Mountains in Colorado, southeasterly through Kansas, Oklahoma, and Arkansas, where it enters the Mississippi River in Desha County. The 448 mile navigation channel which was constructed on the lower portion of this river includes portions of two of its major tributaries, the Verdigris River in Oklahoma and the lower White River in Arkansas. The Arkansas portion of this navigation system consists of three different segments: (1) the lower White River, from its confluence with the Mississippi River to 10 miles upstream, (2) the Arkansas Post Canal, …

Petrology Of The Oceanographer Fracture Zone (35ºn35ºw), Tsugio Shibata

Geology Theses and Dissertations

During a geological and geophysical survey of the Oceanographer Fracture Zone (35°N, 35°W), seventeen dredge hauls containing a variety of rocks were obtained. Petrographic study shows that these rock samples can be classified into six main rock types: fresh basalt, weathered basalt, metabasalt, gabbro, metagabbro, and serpentinite. Most of the dredge hauls were positioned on the steep, southern wall of the fracture zone, and an inference from the dredging results suggests that basalt is the most abundant rock type which outcrops at the junction between the rift valley and the fracture zone; however, as we move away from the junction, …
