Chemical Properties Of Soils And Streams In Natural And Disturbed Forest Ecosystems In The Ouachita Mountains, R. S. Beasley, E. L. Miller, E. R. Lawson

Arkansas Water Resources Center Technical Reports

One year of pre-harvest and five years of post-harvest water chemistry data were collected and analyzed for N03-N, TKN, TP, OP, K and Ca on nine small watersheds in the Ouachita Mountains of central Arkansas. Gross exports of all nutrients except TKN were significantly increased by cl earcutting followed by mechanical site preparation and broadcast burning of slash. Discharge-weighted nutrient concentrations were increased only for OP, K and Ca. The treatment effect was brief, lasting only one year. The first harvest of a selection system regime had no measurable effect on gross losses or concentrations of nutrients. Precipitation chemistry measurements …

Development Of A Combined Quanity And Quality Model For Optimal Groundwater Management, R. C. Peralta, J. Solaimanian, S. A. Prathapar, C. L. Griffis

Arkansas Water Resources Center Technical Reports

Presented is a procedure for incorporating solute transport as linear constraints within computer models for optimizing regional groundwater extraction strategies. The MODCON modelling procedure uses linear goal programming, embedded linearized equations for flow and solute transport and a MOC simulation model. Assumed is 2D flow and solute transport and a dispersed conservative contaminant. The MODCON procedure develops steady groundwater extraction strategies that will satisfy future groundwater quality constraints while simultaneously causing future piezometric heads to be as close to current heads as possible. The procedure is applied to a 160 square mile area in southeastern Arkansas.

Land Use Effects On Ground Water Quality In Carbonate Rock Terrain, Kenneth F. Steele, James C. Adamski

Arkansas Water Resources Center Technical Reports

A control site with a natural setting and an experimental site with significant agriculture land use were studied in the Ozark Region of Arkansas in order to determine the effect of land use on water quality in a carbonate rock terrain. The vast majority of the two sites have the Boone Limestone exposed which combined with the underlying St. Joe is the major aquifer for drinking water in the area. The sites also are similar in terms of lineament patterns (number, length and orientation), soil, slope and vegetation. Ground water samples were collected primarily from springs during three seasons (late …

Growth Rate Of Stony Corals Of Broward County, Florida: Effects From Past Beach Renourishment Projects, Richard E. Dodge, Broward County Erosion Prevention District Environmental Quality Control Board

Marine & Environmental Sciences Faculty Reports

The skeletal growth of hermatypic (reef-building) corals is a sensitive indicator of environmental conditions and perturbations. In particular, excessive sedimentation and turbidity act to depress coral growth because energy expenditure is required to remove sediment and because turbidity reduces light energy necessary for coral health and nutrition.

Normalized annual growth (linear skeletal extension) rates of Broward County, Florida reef-building corals were over 16 years (1985-1970). Star corals (Montastrea annularis) and brain corals (Diploria labyrinthiformis) were collected from each of four reef sites at two depths (9m and 18m). Collection areas were located in the vicinity of …

Comparison Of Littoral And Limnetic Zooplankton Communities Of Lake Mead, Patrick Joseph Sollberger

Publications (WR)

Microfaunal communities were studied in littoral (inshore) and limnetic (offshore) areas of the lower basin in Lake Mead to compare species composition and abundance between the two zones. Planktonic forms (zooplankton) dominated inshore and offshore habitats and the occurrence of littoral species was low. Therefore, high similarity in zooplankton species composition was found among all sampling stations. This was perhaps due to two main factors: (i) the physical and chemical environment among the stations were very similar and (ii) the lack of aquatic vegetation in the littoral zone reduced the occurrence of littoral species.

Although species composition did not vary …

The Exclusive Economic Zone: The Impact Of The 1982 Law Of The Sea Treaty On Worldwide U.S. Naval Operations, John C. Meyer

Marine Affairs Theses and Major Papers

The focus of the Third United Nations Conference on the Law of the Sea (UNCLOS III) was on the development of an international legal regime for the peaceful use of the world's oceans. The maritime powers, particularly the United States, viewed this new regime in terms of preserving traditional high seas freedom of navigation and overflight, and limiting expanding coastal state claims over their adjacent water and airspace. Developing countries, emerging from a period of decolonization, sought to enhance their security and gain economic benefit from this new legal regime, through the seaward extension of claims to jurisdiction over what …

Statistics provided by the Nova Scotia Department of Tourism show that a significant volume of vehicle traffic which enters Nova Scotia originates at points in the United States which are to the south and west of Boston. The existence of this traffic supports the assumption that …

Maritime Boundaries Between Trinidad And Tobago/Venezuela/Barbados And Grenada - Its Impact On Offshore Oil, Patty Marajh

Marine Affairs Theses and Major Papers

The future of the economy of Trinidad and Tobago is heavily dependent upon the exploitation of the hydrocarbon resources in its continental shelf. Trinidad's geographical proximity to the Venezuelan mainland is relevant because both states share the same continental shelf in areas not delimited by the 1942 gulf of Paria Treaty. The continental shelves of Barbados and Grenada also intersect and these areas have not been delimited and defined by any agreement. The current expansion of the exploration and exploitation of crude oil and natural gas have raised several problems within recent years. This thesis will focus attention to the …
