Evaluation Of Detention Basins For Controlling Urban Runoff And Sedimentation, C. T. Haan, A. D. Ward
Evaluation Of Detention Basins For Controlling Urban Runoff And Sedimentation, C. T. Haan, A. D. Ward
KWRRI Research Reports
This report summarizes the work completed under the research project "Evaluation of Dentention Basins for Controlling Urban Runoff and Sedimentation." The main project accomplishments were:
(1) a demonstration of the desirability of considering systems of urban stormwater detention basins as opposed to individual basin design,
(2) the development of a systems analysis approach for least cost selection of a system of dentention basins for meeting a preset hydrologic objective,
(3) the development of a mathematical, computer-based simulation model of the performance of sediment retention basins,
(4) partial verification of the sediment basin model and
(5) the development of design recommendations …
The Distribution Of Several Metals And Cation Exchange Capacity In Sediment Fractions From An Artificial And Natural Marsh, James River, Virginia, William Nivens
OES Theses and Dissertations
In order to examine the mechanisms by which Fe, Mn, Ca, Zn, Cu, Ni and Pb are bound in sediments, a sequential selective extraction procedure was employed on sediment samples collected at an experimental dredge disposal marsh and a neighboring natural marsh located near Windmill Point, James River, Va. The metal concentrations were determined in six phases, interstitial water, exchangeable, easily reducible (oxides of Mn), organic, moderately, reducible (oxides of Fe), and residual fractions. In addition, the cation exchange capacity (CEC) of the sediments was determined as well as the actual role of organics and colloidal iron coatings as they …
Stratigraphy, Sedimentary Petrology, And Depositional Environments Of Tillite In The Upper Precambrian Mount Rogers Formation, Virginia, Richard L. Rexroad
Stratigraphy, Sedimentary Petrology, And Depositional Environments Of Tillite In The Upper Precambrian Mount Rogers Formation, Virginia, Richard L. Rexroad
LSU Historical Dissertations and Theses
The upper member of the upper Precambrian Mount Rogers Formation of southwestern Virginia includes thick units of massive conglomeratic mudstone Interpreted as tillite (Rankin, 1970; Blondeau and Lowe, 1972; Blondeau, 1975; Schwab, 1976). The tillite is composed of unsorted angular plutonic, metamorphic, volcanic, and sedimentary rock fragments enclosed within a matrix of sandy hematitic mudstone. The tillite is interbedded with arkosic sandstone, argillite, and conglomerate. Sedimentary structures and textures of these units suggest deposition by glaciers which protruded from land into a standing body of water as floating ice. Glacial drift was deposited in a large body of water, probably …
Geology Of The Lucea Inlier, Western Jamaica, Jack Grippi
Geology Of The Lucea Inlier, Western Jamaica, Jack Grippi
Geology Theses and Dissertations
The Lucea Inlier exposes a Santonian to Campanian 4 km + thick sequence of shale-siltstone, resedimented volcaniclastics, lenses of shallow-water limestone, micritic limestone, pebbly mudstone and sandy pebble to boulder conglomerate. Clastics were deposited by a variety of gravity flow mechanisms. Petrographically sandstones are lithic or feldspathic arenites and contain only very small amounts of detrital quartz. Structurally the inlier is characterized by simple, open, east-west trending folds. A spaced, vertical axial-planar cleavage is developed in shales and fine siltstones. Two major east-west trending left-lateral fault zones, the Fat Hog Quarter and Maryland faults, cut the inlier into three blocks, …
