Input And Distribution Of Sewage Derived Sedimentary Material Adjacent To Chesapeake-Elizabeth Sewage Outfall, Virginia Beach, Virginia, Robert Carroll Brown Apr 1983

Input And Distribution Of Sewage Derived Sedimentary Material Adjacent To Chesapeake-Elizabeth Sewage Outfall, Virginia Beach, Virginia, Robert Carroll Brown

OES Theses and Dissertations

The concentrations of coprostanol and hydrocarbons were measured in the effluent from the Chesapeake-Elizabeth sewage treatment plant and surface sediments from the area surrounding the effluent discharge site. Most of the coprostanol (>84%) and hydrocarbons (>91%) were associated with particulates in the effluent. Some of these particles were incorporated into the sedimentary column within the study area, while some may have escaped from the area.

The study area is found to be a dynamic area where changes in the percentage and distribution of fine-grained sediments occur over periods of months. The movement of fine-grained sediments is an important …

Long Term Vole Control In Ontario Apple Orchards, Zia Siddiqi, W. D. Blaine, Stan Taylor Mar 1983

Long Term Vole Control In Ontario Apple Orchards, Zia Siddiqi, W. D. Blaine, Stan Taylor

Eastern Pine and Meadow Vole Symposia

The results obtained so far in this 3 year study have shown that the plots with poisoned bait feeder stations suffered significantly less tree girdling than the plots treated with the fall broadcast application of 2% zinc phosphide. Similar timings were also observed in number of voles per plot, however, the vole population was much lower than the previous year. Considerable interest has been shown by apple growers in adopting this method of vole control at a commercial level.

Evaluation And Accessing Of Data For A Water Resources Simulator, Richard C. Peralta, Roberto Arce, Timothy Skergan Mar 1983

Evaluation And Accessing Of Data For A Water Resources Simulator, Richard C. Peralta, Roberto Arce, Timothy Skergan

Arkansas Water Resources Center Technical Reports

This report evaluates the availability of data needed to use a groundwater simulation model for real time conjunctive water management in the Arkansas Grand Prairie. It is assumed that the goal of such management is to protect existing groundwater rights by maintaining water levels so that wells do not go dry, even in time of drought. Sufficient hydrogeologic data exists to use the simulation model to predict the effect of known pumping rates on groundwater levels. Developing an optimal set of "target" levels and annually managing pumping to achieve those levels requires additional data: fall groundwater levels, degree of connection …


Expansion Potential For Irrigation Within The Mississippi Delta Region, Robert N. Shulstad, Ralph D. May, Jon Mark Erstine, Blake N. Phillips, Billy E. Herrington Jr. Mar 1983

Expansion Potential For Irrigation Within The Mississippi Delta Region, Robert N. Shulstad, Ralph D. May, Jon Mark Erstine, Blake N. Phillips, Billy E. Herrington Jr.

Arkansas Water Resources Center Technical Reports

17.6 million acres, or 73 percent, of the Mississippi Delta Region is currently cropland and possesses the physical characteristics of slope, texture and soil type which are recommended for irrigation. Economic feasibility of expanding irrigation by flood, furrow and center pivot methods were examined under 24 scenarios representing two sets of crop prices, yield levels, production costs, opportunity costs and six crop rotations. Irrigation was economically feasible for 56 to 100 percent of the cropland across all scenarios. Approximately 88 percent of the cropland can be economically irrigated with flood or furrow in its present form, 8 percent yield highest …


The Costs And Benefits Of Soil Erosion Control In The North Lake Chicot Watershed, Robert N. Shulstad, C. Tim Osborn, Alan D. Mcqueen Mar 1983

The Costs And Benefits Of Soil Erosion Control In The North Lake Chicot Watershed, Robert N. Shulstad, C. Tim Osborn, Alan D. Mcqueen

Arkansas Water Resources Center Technical Reports

Lake Chicot is divided by a levee into two basins, the high quality northern basin and the extremely polluted southern basin. Water quality in the northern basin of Lake Chicot is diminishing due to soil erosion. Costs for alternative control programs for the seventeen fare, 11,470 acre northern watershed were estimated. Twenty-nine combinations of rotations and best management practices were evaluated. Soil loss can be reduced almost 25 percent from 4.2 tons per acre to 3.2 tons per acre, while increasing net returns to farmers from $83.94 per acre to $107.28 per acre by altering present cropping patterns. A prohibition …

Nutrients And Acid In The Rain And Dry Fallout At Fayetteville, Arkansas (1980-1982), George H. Wagner, Kenneth F. Steele Mar 1983

Nutrients And Acid In The Rain And Dry Fallout At Fayetteville, Arkansas (1980-1982), George H. Wagner, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

Wet and dry fallout at Fayetteville, Arkansas have been collected separately and analyzed since April, 1980. The precipitation-weighted-average pH for two yearly periods of rainfall were 4.72 (6/80-5/81) and 4.75 (6/81-5/82). This corresponds to a concentration of the acid ion, H+, of about 18 parts per billion (ppb). Pure water in equilibrium with the CO2 of the air would have a pH of 5.65 (2.2 ppb of H+). The range of pH during this two year period was 3.86-7.74(140-0 ppb H+) for the rainfall. Aqueous extracts of the dry fallout were always in the 6.75-7.87 pH range, i.e., neutral to …


Monitoring Of Groundwater Levels For Real-Time Conjunctive Water Management, Richard C. Peralta, Vince Mazure, Paul Dutram Mar 1983

Monitoring Of Groundwater Levels For Real-Time Conjunctive Water Management, Richard C. Peralta, Vince Mazure, Paul Dutram

Arkansas Water Resources Center Technical Reports

Water users in the Arkansas Grand Prairie wish to maintain sufficient groundwater levels to: insure adequate groundwater reserves for time of drought, protect themselves from litigation caused by wells going dry, and insure a sustained yield. Achievement of these goals requires regular measurement of groundwater levels. Review of monitoring practice and technology indicates that spring and fall measurements taken over the entire area using steel tape and acoustic device is preferred for most long range planning. Continuous monitoring is indicated for critical parts of the region where saturated thicknesses are small. Desirable attributes of a data collection/transmission system for such …


A Survey Of Soils Irrigated With Arkansas River Water, John T. Gilmour, H. D. Scott, R. E. Baser Mar 1983

A Survey Of Soils Irrigated With Arkansas River Water, John T. Gilmour, H. D. Scott, R. E. Baser

Arkansas Water Resources Center Technical Reports

Interest in the use of Arkansas River water for irrigation has increased recently as land adjacent to the river is converted to crop production and river water is considered as an alternative to depleted underground supplies. Since the Arkansas River can contain elevated concentrations of sodium chloride, this study was designed to determine if soil conditions adverse to crop growth were developing where river water has been used. The impact of river water on sites where river water was used as either the sole source for up to 3 years or as a supplement to another surface source for up …


The Effects Of Forest Harvest On Water Quality And Aquatic Life (Phase I), Edmond J. Bacon Mar 1983

The Effects Of Forest Harvest On Water Quality And Aquatic Life (Phase I), Edmond J. Bacon

Arkansas Water Resources Center Technical Reports

A long term study on the effects of clearcut forest harvest and regeneration was conducted in a representative watershed of the Ouachita National Forest. Fourteen water quality parameters were analyzed to characterize baseline water quality. Water quality was classified as excellent. A total of 350 quantitative benthic samples and 15 ultraviolet light trap samples yielded 173 species of macroinvertebrates. Mean densities of macroinvertebrates ranged from 4,800/m2 to 23,040/m2 and averaged 12,499/m2 in the upper Little Missouri River. Twenty-two quantitative collections of fishes were made at representative riffles and pools. The average biomass estimates for riffles and pools were 5.69 kg/ha …

Hydraulic Analysis Of Surcharged Storm Sewer Systems, Don J. Wood, Gregory C. Heitzman Mar 1983

Hydraulic Analysis Of Surcharged Storm Sewer Systems, Don J. Wood, Gregory C. Heitzman

KWRRI Research Reports

Surcharge in a storm sewer system is the condition in which an entire sewer section is submerged and the pipe is flowing full under pressure. Flow in a surcharged storm sewer is essentially slowly varying unsteady pipe flow and methods for analyzing this type of flow are investigated. In this report the governing equations for unsteady fluid flow in pressurized storm sewers are presented. From these governing equations three numerical models are developed using various assumptions and simplifications. These flow models are applied to several example storm sewer systems under surcharge conditions. Plots of hydraulic grade and flow throughout the …
