Bacterial Source Tracking Of A Watershed Impacted By Cattle Pastures, Celina Phelps

Theses and Dissertations

Pathogenic microorganisms introduced by cattle may be transported to distant locations via watershed runoff. Escherichia coli, Enterococcus spp., and Streptococcus spp. are a few species present in runoff from land impacted by humans, cattle, and wildlife. Initial data reveals that E. coli concentrations in water are greater in areas impacted by cattle than by humans. And, wildlife contributes greater concentration fluctuations than either humans or cattle. When cattle are removed from a pasture, the bacterial concentrations rapidly decrease; however, slight variations in cattle herd size do not appear to significantly influence these counts. Amplified fragment length polymorphisms (AFLP) and repeated-sequence …

Lake Samish Monitoring Project 2006 Final Report, Robin A. Matthews, Joan Vandersypen, Kara Hitchko

Lake Samish

Lake Samish is a valuable aquatic resource, providing public access for boating, fishing, swimming, picnicking, and other water and lakeshore activities. Residents around the lake enjoy outstanding views of both the lake and its surrounding watershed, and the lake serves as a water supply for many of the lakeshore residents.

Lake Samish is located in the Washington State Department of Ecology’s water resource inventory area #3 (WRIA 3), and discharges into Friday Creek, a salmon spawning tributary of the Samish River. The Lake Samish monitoring project was initiated in June 2005 to collect monthly water quality data from the lake …

Predicting Impacts Of Water Management In Coastal Zones By Hydraulic And Salinity Modeling, C. T. Hoanh, N. D. Phong, J. W. Gowing, T. P. Tuong, N. X. Hien, N. D. Dat

International Congress on Environmental Modelling and Software

Tidal effects and salinity intrusion are two defining characteristics of coastal zones. The firstcauses complex variations of water level and unsteady flows in the river and canal network. The second is aconstraint to agriculture and freshwater fishery, but provides suitable conditions for brackish wateraquaculture. These phenomena bring about conflicts in the development of agriculture, fishery andaquaculture due to different requirements of water quality. Hydraulic and salinity modeling have beendeveloped and applied to simulate tidal propagation and salinity intrusion, and to analyze the effects of watermanagement on hydrological and salinity conditions that control land use in the coastal zones. This paperpresents …

Impacts Of Agriculture And Dairy Farming On Groundwater Quality: An Optimization Problem, Tomaz Dentinho, R. Minciardi, M. Robba, Roberto Sacile, V. Silva

International Congress on Environmental Modelling and Software

A decision model for groundwater quality preservation in areas affected by intensive agriculture and dairy farming, with specific reference to the Azores islands, is presented. In these islands, the exigency to find appropriate instruments to support decisions in Integrated Water Management (IWM) is particularly felt because the increase of tourism and the dairy farming have increased water demands and depletion of water quality. An optimization problem, in terms of decision variables, objectives, and constraints is formalized. The physical/chemical/ecological models are embedded as constraints in the decision model. Specifically, four types of models (hydraulic model, chemical model, agricultural model, and dairy …

Development Of An Integrated Decision Support System For Water Quality Control In The Upper Litani Basin, Lebanon, Hamed Assaf, Mark Saadeh

International Congress on Environmental Modelling and Software

Compared to the limited water supply in the Middle East, Lebanon is perceived to be a water rich country. Yet, it faces a growing water supply problem due to many factors including increases in demand, inadequate investment in infrastructure, and deterioration of water quality. Being the foremost water resource in Lebanon, the Litani River is at the center of several major water supply and irrigation schemes. However, the river water quality is severely impacted by the current practice of releasing untreated sewage into its water body, specifically in its upper basin which is home to about half a million inhabitants. …

Decision Support For Nitrogen Management In Tile-Drained Agriculture, P. Heilman, R. W. Malone, L. Mac, Jerry L. Hatfield, L.R. Ahuja, J. Ayen, K. Boyle, R. Kanwar

International Congress on Environmental Modelling and Software

Farmers will adopt alternative management systems to improve water quality more readily if they understand how those management alternatives affect the release of contaminants, crop yields, and ultimately, their net income. We propose a method to address these issues by integrating observed data from field experiments, a comprehensive simulation model, review by local experts, and application through a decision support system by technically trained conservationists. An example for reducing nitrogen loading from tile-drained corn and soybean production in Iowa demonstrates the approach. Fourteen years of observed data from 30 research plots on the Northeast Research and Demonstration Farm near Nashua, …

Ten Steps Applied To Development And Evaluation Of Process-Based Biogeochemical Models Of Estuaries, Barbara J. Robson, Ian T. Webster, David P. Hamilton, Terence Chan, Teemu Kokkonen

International Congress on Environmental Modelling and Software

The procedures involved in model development may be set out ten-step process, beginning with defining the purpose of the model and ending with evaluation of the appropriateness and utility of the completed model. This process, recently outlined by Jakerman et al. [2006], is often iterative as model development is a continuous process that refines and improves the indented capacity of the model. Here, we show how the ten steps of model development are relevant to process-based biogeochemical modeling of aquatic systems, using examples from two case studies: a model of phytoplankton succession and nutrient concentrations in the Swan-Canning Estuary (Western …

Application Of The Elbe-Dss To Water Quality Issues, Michael Matthies, Jürgen Berlekamp, N. Grafa, Sven Lautenbach

International Congress on Environmental Modelling and Software

The Decision Support System for the Elbe river basin (Elbe-DSS) was developed as a tool to assist water managers. A user can select various measures and compare them to evaluate their relative effectiveness in achieving a good ecological and chemical status of the Elbe and its tributaries. Two subsystems, the catchment and the river network, represent the whole German Elbe river basin (96.900 km2). This approach allows for better representation of management objectives, scenario development and decision-making. The implemented measures can be classified into the groups: ‘reduction of pollution from urban areas’, ‘modification of agricultural land allocation’, ‘changes in agricultural …

Willingness To Pay For Improved Water Service In Manaus, Amazonas, Brazil, James F. Casey

James F Casey

The 1.5 million residents of the city of Manaus form the epicenter for economic activity and development in the Amazon Basin. The current water treatment facilities were built when there were a mere 100,000 people living here. The fifteen-fold increase in population has made access to water a major public health concern. Families that can afford to buy bottled water do and those that can not are susceptible to water-borne disease and illness at an ever-increasing rate. In order to determine how much citizens are willing to pay for universal access to water service in the home, the University of …

Growing Chinese Cabbage In Western Australia, John Burt, Dennis Phillips, David Gatter

Bulletins 4000 -

Chinese cabbage is a member of the Brassiceae family, which may be called brassicas, crucifers or cole crops. This includes various crops such as broccoli, Brussels sprouts, cauliflower, cabbage, radish, turnips, swedes and weeds such as wild radish.

In general trade, the term Chinese cabbage can loosely be given to both the heading types (Brasssica rapa L. subsp. pekinensis) and to non heading types such as pak-choi (Brassica rapa L. subsp. chinensis). This Bulletin deals with the heading type of Chinese cabbage. The Chinese name is Wong Bok, and this name is often used in Australia.
