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.

Environmental Air Pollution Analysis In Selected Areas Of Abu Dhabi Emirate, Mahfoodh Abdulla Mohammed Darbool
Environmental Air Pollution Analysis In Selected Areas Of Abu Dhabi Emirate, Mahfoodh Abdulla Mohammed Darbool
Theses
There are little data available for environmental pollution, as well as air pollution and statistical information published in the United Arab Emirates. Especially, Abu Dhabi Emirate, has been the location of the UAE's most persistent and extreme levels of industrial oil waste and chemical smog and air pollutants which produces sulphur dioxide emission. In addition, has a high vehicle population, which produces carbon monoxide emission from the motor vehicle exhaust. The acute toxicity of carbon monoxide (CO) has long been recognized and well documented. The motor vehicle is by far the largest contributor to Co accounting for 55% of total …

The Effects Of Chromated Copper-Arsenate (Cca) Pressure-Treated Wood On Local Sediments And Benthos In A Freshwater Lake, William A. Romeo
The Effects Of Chromated Copper-Arsenate (Cca) Pressure-Treated Wood On Local Sediments And Benthos In A Freshwater Lake, William A. Romeo
Theses
This study looked at the sediment and benthic organism effects of exposure to a Chromated Copper-Arsenate (CCA) treated wood bulkhead in a lake environment with respect to 1) the leaching and accumulation of chromium, copper and arsenic in the nearby sediments, 2) accumulation of these metals in local benthic organisms and 3) the effects of these metals on the local benthic community structure. Sediment samples, taken at regular distances away from a CCA bulkhead and three reference areas in a freshwater lake in Wayne, NJ, were sieved to remove the fine particle fraction (<70µm) which was then analyzed for the metals of concern. Benthic organisms were sampled at the same locations, enumerated, identified, dried and also analyzed for the metals in question. Analysis of sediment metal concentrations revealed high levels of copper at all sampling locations. This was attributed to the annual addition and accumulation Of CuS04 added to the lake. There …70µm)>

An Interdisciplinary Water Quality Curriculum For Middle School Students, Barbara Michelle Cleveland
An Interdisciplinary Water Quality Curriculum For Middle School Students, Barbara Michelle Cleveland
All Graduate Projects
An interdisciplinary curriculum correlating water quality with the disciplines of physical science and mathematics for 6th grade middle school students was developed. Literature examined indicates that the opportunity to explore key concepts and significant issues using an integrated approach provided greater opportunity to formulate meaningful connections between disciplines studied and that achievement was enhanced. The Learning units were developed for use at Wilson Middle School in Yakima, Washington.

A Guide For Extending Nature Lessons At The Yakima Arboretum, Marilou Cori Kinder
All Graduate Projects
The importance of providing a hands on natural environment curriculum was examined. Sources from 1938-1996 were found supporting the importance of such a curriculum. A search was conducted on the availability of a natural habitat curriculum that used a local resource. The search discovered the Yakima Arboretum had seven areas of interest along with a packet of brief lesson suggestions. These lessons were extended to include classroom activities that would provide students with background knowledge prior to a field trip to the Arboretum.

Tourism: Who Needs It?, Joan S. Remington, Marcel R. Escoffier
Hospitality Review
Is tourism economically beneficial? If so, who benefits? How much of the money generated through tourism can be channeled into other projects so desperately needed by the community without harming the local tour market? Will tourism continue to grow forever, or is there an end in sight? The authors discuss how tourism will change in approaching the next century: and how people will change if tourism is to remain such an important economic facto
Evaluating Bighorn Habitat: A Landscape Approach, William C. Dunn
Evaluating Bighorn Habitat: A Landscape Approach, William C. Dunn
United States Bureau of Land Management: Staff Publications
This technical note describes a method that incorporates a landscape approach with the use of Geographic Information Systems (GIs) to measure habitat and impacts for Rocky Mountain and desert bighorn sheep and to rank potential transplant sites. A landscape approach, in which habitat is viewed from a large-scale perspective as an assemblage of patches, is used because: (1) bighorn habitat is naturally patchy due to the affinity of bighorn for terrain that is both open and mountainous; (2) fragmentation (i.e., increased patchiness) often is the most severe consequence of human disturbance; and (3) the proximity and distribution of neighboring bighorn …

Performance Of Vegetative Filter Strips With Varying Pollutant Source And Filter Strip Lengths, Puneet Srivastava, Dwayne R. Edwards, Tommy C. Daniel, Philip A. Moore Jr., Thomas A. Costello
Biosystems and Agricultural Engineering Faculty Publications
Vegetative filter strips (VFS) can reduce runoff losses of pollutants such as nitrogen (N) and phosphorus (P) from land areas treated with fertilizers. While VFS effectiveness is considered to depend on lengths of pollutant source and VFS areas, there is little experimental evidence of this dependence, particularly when the pollutant source is manure-treated pasture. This study assessed the effects of pollutant source area (fescue pasture treated with poultry litter) length and VFS (fescue pasture) length on VFS removal of nitrate N (NO3-N), ammonia N (NH3-N), total Kjeldahl N (TKN), ortho-P (PO4-P), total P (TP), …

Simulation Of Runoff Transport Of Animal Manure Constituents, Yang Wang, Dwayne R. Edwards, Tommy C. Daniel, H. Don Scott
Biosystems and Agricultural Engineering Faculty Publications
Runoff losses of land-applied animal manure constituents can adversely affect the quality of downstream waters. Reliable mathematical simulation models can help estimate runoff losses of animal manure constituents and identify management measures to reduce these losses. The objective of this study was to develop and calibrate an event-based simulation model to describe the runoff transport of solids (soil and manure particles) and nutrients (nitrogen and phosphorus) from areas treated with animal manure. The resulting model, consisting of linked hydrology, soil/manure transport, and nutrient transport components, is process-oriented and uses measurable parameters to the greatest degree possible. The three components of …
A Direct, Approximate Solution To The Modified Green-Ampt Infiltration Equation, Puneet Srivastava, Thomas A. Costello, Dwayne R. Edwards
A Direct, Approximate Solution To The Modified Green-Ampt Infiltration Equation, Puneet Srivastava, Thomas A. Costello, Dwayne R. Edwards
Biosystems and Agricultural Engineering Faculty Publications
Accurately predicting the rainfall-runoff process is of vital importance for water quality models as well as for correct design of various types of hydraulic structures. This article presents a method of describing the cumulative infiltration process as an explicit function of time using an approximation to the modified Green-Ampt equation given by Mein and Larson (1971). The resulting equation is helpful in predicting cumulative infiltration and therefore infiltration capacity for computer simulation models. The proposed method takes about 50% less time than the usual iterative technique for the same degree of accuracy. The maximum error due to approximation was 1% …
