Assessing the effectiveness and environmental impacts of using natural flocculants to manage turbidity

Creator:: Kegley, Laura J.
Abstract:: The objective of this research was to determine the feasibility of using chitosan as a natural flocculant to control turbidity during in-stream construction work. A series of field tests in Oak Creek, Corvallis, OR were conducted in order to test the effectiveness for turbidity control and the environmental impacts of...

Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

Creator:: Gillman, Reva A.
Abstract:: The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

The agronomic, environmental, and economic implications of the introduction of terbacil for weed control in Oregon commercial peppermint operations

Creator:: Harris, James O.
Abstract:: The use of terbacil for weed control was adapted by a high percentage of Oregon peppermint growers soon after its introduction in 1967. To help clarify some of the implications of terbacil usage, three studies were undertaken to collect information concerning (a) the movement and build-up of terbacil in various...

Evaluating dairy waste management systems ̓influence on fecal coliform concentration in runoff

Creator:: Grismer, Mark Edward
Abstract:: This paper examines the environmental factors influencing the die-off and transport of fecal coliform bacteria present in wastes applied to the land surface. These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers...

An analysis of two adjacent agricultural watersheds in west central Oregon

Creator:: Schoeneberger, Philip James
Abstract:: Two small adjacent watersheds on the west-central edge of the Willamette Valley of western Oregon were studied. Information was gathered on existing conditions to determine the suitability of the two watersheds for a paired-watershed study design. A soil survey was conducted using slightly modified soil series previously established for the...

An experimental investigation into the dynamic collapse phase of drilling fluid discharged into a stratified, flowing environment

Creator:: Albright, Stephen L.
Abstract:: Dumping drilling mud from offshore drilling rigs into the ocean could have a negative impact on the marine environment. Due to this possible impact, the Offshore Operators Committee (OOC) has deemed it necessary to predict the fate of drilling mud discharged into the ocean. Through the funding of OOC and...
