Environmental Resources
: Issues and Options, NREM 210/PEPS 210

Student literacy and appreciation of food production systems, use of natural resources, and the environment often seem at odds. Students have difficulty in understanding the complex interactions between food and fiber production systems, population growth, and environmental quality. The political and popular discourse on these subjects is often polarized and contentious, rather than thoughtful and illuminating. This science-based course provides students with the foundation for making critical judgments concerning agriculture, management of natural resources, and the environment.

Small Watershed Modeling, NREM 491 (Spring 2005)

This course will introduce students to process-based modeling of watershed with emphasis on current concepts and model applications. It deals with the characterization and simulation of small watershed systems including land and channel phase hydrologic processes and pollutant transport processes. Significant time will be given to the investigation of the structure and capabilities of current watershed computer models. The students will have an opportunity for "hands-on" use of some currently available watershed models and will be expected to use computers extensively.

Soil Erosion and Conservation, NREM 461

The course will evaluate past and present problems in soil and water conservation. The principles of water and wind erosion will be discussed and students will learn to use the Revised Universal Soil Loss Equation and the Wind Erosion Prediction Equation. Water conservation issues such as irrigation, drainage, salinization, and storm water management will be discussed. Emerging issues such as total maximum daily load development, land-based threats to coastal zones, and integrated watershed management will be covered. Finally, programs and agencies responsible for soil and water conservation in the U.S. and the international community will be studied.

Watershed Hydrology, NREM 662

This course will provide students with a fundamental understanding of the hydrologic cycle, the interactions among the hydrosphere, atmosphere, and land-use management effects on the amount, timing, and quality of water resources. Students will also develop the ability to quantify the magnitude of hydrologic entities in small watersheds. They will have some hands on watershed management such as rainfall, effective rainfall, canopy rainfall interception, evapotranspiration, infiltration, stream flow, and hydrographs.
