Effects Of Zebra Mussel, Dreissena Polymorpha, Infestation On Lake Dardanelle Water Quality, Charles J. Gagen, Joseph N. Stoeckel

Arkansas Water Resources Center Technical Reports

Zebra mussels recently invaded southern waterways including the Arkansas River. Exponential population growth and high filtration capacity of dense populations could alter reservoir ecosystem function. Furthermore, they attach to hard surfaces; thus, threatening normal operations of many artificial structures. We designed this study to provide baseline data prior to high population levels of zebra mussels in Lake Dardanelle. The characterization of spatial and temporal variability in water quality, zooplankton, phytoplankton, and macrophytes will allow testing of several hypotheses. We sampled zebra mussel density and zooplankton at four fixed sites and the other key variables at three of these sites biweekly …

Assessment Of Effectiveness Of Buffer Zones In Removing Impurities In Runoff From Areas Treated With Poultry Litter. Part Ii: Source Areas To Buffer Areas Ratio Effects, P. Srivastava, D. R. Edards, T. C. Daniel

Arkansas Water Resources Center Technical Reports

Vegetative filter strips (VFS) are known to reduce runoff losses of nutrients. solids. and other materials from land areas treated with fertilizers . Although VFS effectiveness is known to depend partially on the relative lengths of filter and pollutant source areas. there is little experimental evidence available to quantify this dependence. This is particularly the case when VFS are implemented down-slope of pasture areas treated with animal manures such as poultry litter. This study assessed the influences of pollutant source area (treated with poultry litter) and VFS lengths on VFS removal of total Kjeldahl nitrogen (TKN). ammonia nitrogen (NH3 -N …

Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt

Natural resources published reports

Buntine West/Wubin land Conservation District was formed when a number of landholders wanted to extend and join on to some existing deep drains. At first the group concentrated on the deep drains with some farmers joining on anda project to connect the drains up througha naturally occurring saline area and to run the main drain into a salt lake system. Funding was attained for 50% of the project and farmers with drains paid for the rest. It was considered unfair for landowners whose land this drain went through to pay all the cost as it was not draining arable land. …

A Search For The Seasonal Variability On The Depositional Fluxes Of 7Be And 210Pb, M. Baskaran

Environmental Science and Geology Faculty Research Publications

Investigations of the atmospheric fallout of ⁷Be and ²¹⁰Pb in many places around the globe indicate that there are seasonal variations on the depositional fluxes of these nuclides: high in winter in a few places, while in most places the high occurs in spring. However, these earlier studies did not address quantitatively the corresponding seasonal variations of the amount of precipitation during these periods. Data on the depositional fluxes of ⁷Be and ²¹⁰Pb in Galveston, Texas, during the years 1989–1991 indicate that the seasonal variation is not uniform from year to year, and the amount of …

Relative Soil Aeration In A Cultivated Prairie Pothole, Alan Olness, J. A. Staricka, J. A. Daniel, G. R. Benoit, J. L. Rinke

Journal of the Minnesota Academy of Science

Many small prairie potholes receive surface runoff from their catchments and serve as a focal point of ground water recharge. Soil aeration controls the solubility and form of many soil chemicals. Platinum electrodes are sensitive to oxygen and provide a very sensitive indicator of its presence. Electrodes were installed at the 15-, 30-, and 45-cm depth across two transects within a shallow, cultivated depression which serves as a recharge site for groundwater. Soils on the rim of the depression remained aerobic throughout two consecutive cropping years even at 45 cm. Soils within the depression became anaerobic briefly in the first …

Relating United States Crop Land Use To Natural Resources And Climate Change, K. G. Hubbard, F. J. Flores-Mendoza

National Drought Mitigation Center: Faculty Publications

Crop production depends not only on the yield but also on the area harvested. The yield response to climate change has been widely examined, but the sensitivity of crop land use to hypothetical climate change has not been examined directly. Crop land-use regression models for estimating crop area indices (CAIs) - the percent of land used for corn, soybean, wheat, and sorghum production - are presented. Inputs to the models include available water-holding capacity of the soil, percent of land available for rain-fed agricultural production, annual precipitation, and annual temperature. The total variance of CAI explained by the models ranged …

Geologic Map Of Morrill County, Nebraska, James B. Swinehart, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Morrill County, Nebraska, is perhaps the most geologically interesting county in the panhandle of Nebraska. Surficial deposits of alluvium, colluvium, loess, and eolian sand of Quaternary age cover large parts of the county. Holocene and latest Pleistocene(?) eolian sand as much as 150 It thick covers much of the area north of North Platte Valley and mantles Quaternary alluvial deposits to the south. A thin veneer of loess overlies bedrock in the uplands of the southern part of the county. Alluvium underlies the valley floors and caps river and stream terraces. Two units of older Quaternary alluvium are exposed in …

Impact Of Erosion, Mass Wasting, And Sedimentation On Human Activities In The Río Grande Basin, Jujuy Province, Argentina, Waldo Chayle, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Nearly all dry mountainous regions are affected by severe erosion, floods, and debris flows during times of intense precipitation. The lithology, geologic structure, and climate in Jujuy Province, Argentina combine to place at serious risk the people who live along the Río Grande, the major river that drains the east side of the Cordillera Oriental and the west side of the Sierras Subandinas. Nearly all precipitation falls during summer (January–March) with little during the remainder of the year; most of the basin is semiarid to arid, although the southern end has a humid subtropical climate. Relief is great, as much …

Freshwater Imperative - Executive Summary, Long Term Ecological Research Network

Long Term Ecological Research Network

Fresh water is a strategic resource in a rapidly changing world. It is a source of energy, an avenue of transportation, habitat for a myriad of organisms, and essential for life. Fresh water structures the physical landscape, is a central feature of climate, and exerts major influences on economic growth and demographic patterns. Yet, as the human population increases, more and more demands are placed on freshwater ecosystems. Already, sufficient clean water and healthy aquatic habitats have become a rare natural resource.

Understanding the abilities and limits of freshwater ecosystems to respond to human-generated pressures has become vital to long-term …
