Temporal Variability Of Organic C And Nitrate In A Shallow Aquifer, D. E. Clay, S. A. Clay, T. B. Moorman, K. Brix-Davis, K. A. Scholes, A. R. Bender

Agronomy, Horticulture and Plant Science Faculty Publications

The loading of organic substrates into shallow aquifers may follow seasonal cycles, which will impact the transport and fate of agrichemicals. The objective of this research was to measure temporal changes in the groundwater dissolved organic C (DOC) and nitrate concentrations. Groundwater monitoring wells were installed and sediment samples from the aquifer were collected in 1991. Sediment samples were used to evaluate denitrification potentials, while water samples were collected at periodic intervals in 1992 and 1993 from the surface of the aquifer. Water samples were analyzed for nitrate-N and DOC-C. Denitrification was observed in sediment amended with nitrate and incubated …

(1) to initiate the establishment of a hydrologic database archive necessary for characterizing rainfall and runoff associated with flash-flooding;
(2) identification of appropriate modeling approaches for evaluating site-specific flash-flood runoff behavior.

Specific tasks accomplished to meet the objectives include the following:
(1) development of a rainfall and streamflow data archive using existing measurement gages and identification of the rain gage data from two sources for preliminary quality control;

Global Climate Change Response Program, Water Yield In Semiarid Environment Under Projected Climate Change, United States Department Of The Interior

Water

This paper presents the practical application of a distributed parameter climate vegetation hydrologic model (CVHM) and its ability to simulate hydrologic response under existing conditions and under assumed CO₂-induced climate and vegetation change. Applying the model to the Weber River basin provided a basis for determining the impacts of climate change on the hydrologic response. By using a "what if" scenario this model included the changes in plant transpiration rates and in vegetation cover under a CO₂-altered climate change and the effects of these changes on water yield.

Landuse And Landcover Classification For Independence, Union, Bradley And Cleveland Counties Of Arkansas, H. Don Scott, Kimberly Hofer

Arkansas Water Resources Center Technical Reports

Landuse/landcover (LULC} is a function of natural factors such as soils, climate and water and of anthropogenic factors such as predominant use. In Arkansas, the primary use of the land varies depending on the physiographic region. For example, in the Mississippi Delta region of eastern Arkansas row crop agriculture predominates, whereas in the Gulf Coastal Plains forestry dominates. In both regions LULC is spatially and temporally . variable. Knowledge of LULC can be used in estimating the potential for agricultural production, locations of critical ecological areas, siting of homes, small businesses, industries, roads and landfills as well as source areas …

Land Use Patterns In Relation To Lake Water Quality In The North Pond Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: East and North Ponds (2011, 1999, 1996, 1991)

Human activity within the watershed can greatly accelerate the eutrophication process by increasing the rate at which nutrients such as phosphorus and nitrogen enter the lake (Fernandez et al. 1992). Increased nutrient loading causes dramatic increases in algal populations resulting in algal blooms. Many New England lakes develop a greenish tint because of algal blooms during early summer or early fall. Populations of bacteria which feed on organic material rise because of increased food supply. Bacterial activity decreases the level of dissolved oxygen in the lake (Henderson-Seller and Markland, 1987). A sharp decrease in dissolved oxygen levels can cause massive …

Task Lll Report: Deficit Analysis, L. Ormsbee, J. Herman

KWRRI Research Reports

This report summarizes the water supply deficit results of Phase lll of the KWRRI Kentucky River Basin Water Supply Assessment Study commissioned by the Kentucky River Authority. The purpose of Phase lll is to quantify water supply in the Kentucky River Basin during a severe drought for the existing supply system/resources under current and projected demand forecasts. A quantification of the susceptibility of the basin to a severe drought is necessary for the Authority to properly develop a long-range water supply plan.

This is part 3 of a three part Assessment Study of the River basin water supply.

Simulated Growth And Production Of Endangered Snake River Sockeye Salmon: Assessing Management Strategies For The Nursery Lakes, Chris Luecke, Wayne A. Wurtsbaugh, Phaedra E. Budy, H. P. Gross

Watershed Sciences Faculty Publications

We examined the potential of employing a series of lake management strategies to enhance production of endangered Snake River sockeye salmon (Oncorhynchus nerka) in its historical nursery lakes in central Idaho. We used a combination of limnological sampling, experimentation, and simulation modeling to assess effects of lake fertilization and kokanee reduction on growth and survival of juvenile sockeye salmon. Juvenile sockeye salmon from a broodstock of this endangered species are being introduced into the lakes from 1995 to 1998. Results of our analyses indicated that several lakes were suitable for receiving broodstock progeny. Field experimentation and simulation modeling indicated that …

Something Fishy Is Going On - Aquaculture, David Berry

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

Aquaculture id Australia's fastest growing primary industry. Product from fish farms is currently valued at $399 million, forecast to exceed $5oo million by 2000.

Whilst the figure pales into insignificance alongside world production (about $45 billion) it does represent a huge window of opportunity for prospective investors and for Australian primary producers who are keen to diversify.

David Berry reports on the prospects for yabbie and marron farming in Western Australia.

Water Use Estimation And Forecasting For The Kentucky River Basin: A Preliminary Draft Report, Glenn C. Blomquist, William Hoyt, Dayuan Hu, Colleeen G. Scott

KWRRI Research Reports

We estimate aggregate monthly water use for summer, peak demand and nonsummer off-peak demand periods for the Kentucky River Basin. Using Kentucky Division of Water use data, U.S. Census data for county demographic and economic conditions, and U.S. Weather Service data for weather conditions we estimate use for the 1970-1993 period. Our model allows for idiosyncratic effects of each of the 27 counties in the sample. We find factors such as population and manufacturing employment effect use and temperature and rainfall in current and preceding months effect use during the summer, peak period. The model predicts well within the sample …

Comparison Of Daily Water Table Depth Prediction By Four Simulation Models, Eric D. Desmond, Andrew D. Ward, Norman R. Fausey, Stephen R. Workman

Biosystems and Agricultural Engineering Faculty Publications

The Agricultural Drainage And Pesticide Transport (ADAPT) model was compared to the water management simulation models DRAINMOD, SWATREN, and PREFLO. SWATREN and PREFLO are one-dimensional finite-difference models while ADAPT and DRAINMOD are one-dimensional mass balance models. ADAPT, an extension of the computer model GLEAMS, also provides chemical transport information. All four models were tested against field data from Aurora, North Carolina. Observed water table depth data were collected during 1973 through 1977 from a water table management field experiment with three subsurface drain spacing treatments of 7.5, 15, and 30 m.

Both the standard error of estimate and the average …

Effects Of Daphnia Availability On Growth And Food Consumption Of Rainbow Trout In Two Utah Reservoirs, R. Tabor, Chris Luecke, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

We monitored the diet and growth of stocked rainbow trout Oncorhynchus mykiss in two Utah reservoirs during 1986 and 1989–1990. For the first month after stocking, juvenile rainbow trout in both reservoirs fed extensively on large Daphnia spp. In East Canyon Reservoir where Daphnia were abundant, this pattern continued throughout the summer, fall, and winter. Growth of rainbow trout in East Canyon Reservoir was generally good throughout 1989–1990. In Causey Reservoir, where Daphnia were less abundant and smaller, rainbow trout fed progressively less on smaller Daphnia throughout the summer, fall, and winter, while other prey items (snails, aquatic insects, and …
