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...
This report examines 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 the...
An experimental protocol to determine the effects of temperature and light on the dissipation of xenobiotic substances in pesticide deposits is presented. A factorial design laboratory experiment is used to develop isothermal models of the dissipation of compounds over time in authentic pesticide deposits on excised leaves arid glass microscope...
Stream buffer strips are an important tool for protecting the stream environment. This research documents the losses from 40 stream buffer strips, in the Western Cascades of Oregon, established 1 to 15 years before the study. Predictive equations are developed
which identify the major reasons for buffer strip losses. Losses...
Logging on skid trails restricted to 10 percent or less of the harvested stand can reduce the area of compacted soil by at least two-thirds, In a comparative study, productivity of Douglas-fir logs per hour was just as great In an area with designated trails as In an adjacent area...
