Population Impacts On Surface Water Quality In The Little Papillion Creek Watershed., Steven L. Bartosh Aug 2002

Population Impacts On Surface Water Quality In The Little Papillion Creek Watershed., Steven L. Bartosh

Student Work

This study involved monthly monitoring of water quality at 30 rural and urban sites in Douglas County, Nebraska from January 1996, to December 1996. Eight water parameters were measured or calculated for each sample and the results were then analyzed. Nitrate, potassium, chloride and sodium were the four parameters used in the thesis to display the strongest relationships between the land uses and quality of water. This thesis examines how rural and urban land uses affect the concentrations of the chemical constituents. Additionally, this thesis will correlate the number of businesses and residents with nitrate, potassium, chloride and sodium. Rural …


Hyperspectral Reflectance From Restored Tallgrass Prairie Under Different Management., Sung-Jun Kim Apr 2002

Hyperspectral Reflectance From Restored Tallgrass Prairie Under Different Management., Sung-Jun Kim

Student Work

Tallgrass Prairie has been highly fragmented and severely disturbed by overgrazing and land development with most of the tallgrass prairie remnants less than 100 hectares in size. The small size results in increased edge effects, potential invasion by undesirable or exotic species, low genetic diversity in local populations and increased extinction rates. To conserve tallgrass prairie remnants, some types of active management are needed. The most common management methods are prescribed burning, haying and mowing. It is essential to monitor the status of tallgrass prairie in order to determine if management objectives are being met. In this study, close-range hyperspectral …
