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 …

Geology Of The Stateline District, Utah-Nevada, Terry Moore Collins

Masters Theses

"The rocks exposed in the Stateline District, Iron County, Utah and Lincoln County, Nevada, are Tertiary volcanics, which serve as hosts for gold and silver bearing quartz veins. The Miocene rhyolites and dellenites, a possible caldera, cupola-associated rock textures, and the faults and styles of deformations indicate the geologic setting of Stateline is in harmony with the tectonic framework of the southern Great Basin. Four map units, subdivided into nine members, are recognized. X-ray fluorescence analyses for SiO₂, TiO₂, Fe₂O₃, CaO, and K₂O differentiated the map units, while variations in the primary quartz, sanadine, plagioclase, biotite, hornblende, and total crystal …

Lower Mississippian Sedimentation In Northwestern Montana, Forest E. Haines

Doctoral Dissertations

"Thirty-three measured sections, nine with thin sections and insoluble residues, were studied to determine the depositional history of the Allan Mountain Limestone and the lower member of the Castle Reef Dolomite of the Madison Group in northwestern Montana.

The Allan Mountain base is a fossiliferous limestone, herein named the Brownback Gulch Member, which thickens and becomes cherty to the southwest where the section at Lone Butte resembles that of the Bridger Range Waulsortian-type reefs. A crinoidal lag deposit marks a dis- conformity at the top. In the overlying silty limestone member a thin black shale (Unit 1) grades into normal …

Nitrobacter In Mammoth Cave, C. B. Fliermans, E. L. Schmidt

International Journal of Speleology

Mammoth Cave, a large limestone cavern in Mammoth Cave National Park in the Central Kentucky karst, was first mined for saltpetre in 1808 and was a major source of nitrates used in the manufacture of gunpowder during the War of 1812. The mechanism of saltpetre formation is unknown, although hypotheses encompassing both biotic and abiotic functions have been suggested. Present studies were conducted in various saltpetre caves using species specific fluorescent antibodies in order to determine if the chemoautotroph, Nitrobacter, were present. Population densities and species distribution of Nitrobacter were studied in relation to chemical and physical parameters for …

Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard Living In Different Habitats I. Morphology, Gary W. Dickson

International Journal of Speleology

Populations of the troglobitic (i.e., obligatory cavernicole) amphipod Crangonyx antennatus living in two distinct aquatic habitats were examined for possible morphological variation. Collections were made seasonally for one year in six Lee Co., Virginia caves, three with mud-bottom pools and three with small gravel-bottom streams. Environmental parameters thought to influence population variation were recorded for each of the six caves. Body length of mature amphipods was found to be greater in the mud-bottom pool habitats, whereas stream amphipods possessed more first antennal segments per unit body length. Variation was also observed in integument coloration; stream amphipods were characterized by a …

Geology Of The Northern Lewis Hills, Western Newfoundland, Jeffrey Alan Karson

Geology Theses and Dissertations

The Lewis Hills is the southernmost of the four Bay of Islands Ophiolite Complex massifs. These massifs are considered to be the dissected remnants of a once nearly continuous thrust slice of oceanic crust and upper mantle of Early Ordovician age. The Lewis Hills Massif may be divided into three north south trending zones. The eastern zone (Bay of Islands Complex) is composed of variably deformed and recrystallized gabbro, troctolite, wehrlite and dunite cumulates and harzburgite tectonites. The western zone (Little Port Assemblage) consists of greenschist facies metagabbros, diabase dikes and minor quartz-diorite bodies. The central zone (Mount Barren Assemblage) …

Stratigraphy, Depositional Environment And Structure Of The Taconic Allochthon, Central Washington County, New York, Louise D. Jacobi

Geology Theses and Dissertations

The Taconic Allochthon contains rocks of Cambrian (?), Cambrian and Ordovician age. It measures approximately 200 kilometers by 25 kilometers and is located in contiguous sections of New York, Vermont, Massachusetts, and Connecticut. The rocks are predominantly slates with lesser amounts of arenites, wackes, limestone, chert, and conglomerates. All have been subjected to chlorite or biotite grade metamorphism and two tectonic deformations. The study area in central Washington County, New York, contains most of the Taconic sequence, and because of both natural and man-made exposure it is more accessible than most other locations. A lithostratigraphic column has been identified which …

Water Supplies On Wheatbelt Farms : A General Picture, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

In good rainfall years, farm dams provide water fo more than 50 per cent of the total stock in the wheatbelt.

Other sources include ground water supplies and the piped Comprehensive Water Scheme.

The March 1970 census included questions on farm water supplies including how farmers coped in the 1969-70 drought.

Farm Dams In The Wheatbelt, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

Of the estimated 76 000 farm dams in the wheatbelt, about 8 per cent either leak or are salt affected. The remaining 70 000 dams are capable of holding water for livestock use and can be regarded as sercicable dams.

A great many of the serviceable dams are unreliable water supplies due to the combined effects of lack of runoff from catchments, shallow depth of storage and small size of storage in relation to expected demand from livestock and evaporation loss.

Design Standards For Farm Surface Water Supplies, J L. Frith

Journal of the Department of Agriculture, Western Australia, Series 4

Design is usually concerned with getting adequate return from limited recources. Farm dams which dry up represent dam failure. Less seriously, so too do dams which, although not drying out, never fill; they waste a recource.

Geology Of The Southern Half Of The Stoutland, Missouri Quadrangle, Chester Encell Nichols

Doctoral Dissertations

"The dissertation area lies on the western flank of the Ozark uplift between Lebanon and Camdenton, Missouri. In the northwestern corner of the study area a portion of the Decaturville cryptoexplosive structure is exposed. The dominant structure outside the disturbed zone is a northwest-trending asymmetrical anticline with a subsidiary normal fault dipping southwest on the steeper southwest limb.

The area is mapped in considerable detail in order to describe subtle structural features. To overcome a problem of poor exposures, new key beds are defined which greatly increase structural control. Significant structures recognized as a result are the Dry Auglaize anticline, …
