Runoff Using A Combined Geographic Information System And Curve Number Approach, Keshia M. Koehn
Runoff Using A Combined Geographic Information System And Curve Number Approach, Keshia M. Koehn
Inquiry: The University of Arkansas Undergraduate Research Journal
Stormwater runoff can transport nutrients, sediments, chemicals, and pathogens to surface water bodies. Managing runoff is crucial to preserving water quality in rapidly developing urban watersheds like Northwest Arkansas. A watershed containing much of the University of Arkansas campus was identified as the target area for this study because stormwater from this location drains into the West Fork of the White River, designated as an impaired water body due to siltation. The project objective was to develop a methodology to test existing stormwater drainage infrastructure, identify potential areas of improvement, and estimate potentially contaminated runoff by combining two widely used …
Land-Use/Land-Cover Characterization Using An Object-Based Classifier For The Buffalo River Sub-Basin In North-Central Arkansas, Robert C. Weih Jr., D. White Jr.
Land-Use/Land-Cover Characterization Using An Object-Based Classifier For The Buffalo River Sub-Basin In North-Central Arkansas, Robert C. Weih Jr., D. White Jr.
Journal of the Arkansas Academy of Science
Sensors for remote sensing have improved enormously over the past few years and now deliver high resolution multispectral data on an operational basis. Most Land-use/Land-cover (LULC) classifications of high spatial resolution imagery, however, still rely on basic image processing concepts (i.e., image classification using single pixel-based classifiers) developed in the 1970s. This study developed the methodology using an object-based classifier to characterize the LULC for the Buffalo River sub-basin and surrounding areas with a 0.81- hectare (2-acre) minimum mapping unit (MMU). Base imagery for the 11-county classification was orthorectified color-infrared aerial photographs taken from 2000 to 2002 with a one-meter …
Characterization And Analysis Of Hailstorms In The Northern Great Plains, Thomas Sando
Characterization And Analysis Of Hailstorms In The Northern Great Plains, Thomas Sando
The Journal of Undergraduate Research
Hail is a meteorological occurrence that appears frequently during spring and summer across the Northern Great Plains. This paper first characterizes patterns associated with reported hail events occurring within a five-state region (North Dakota, Minnesota, South Dakota, Iowa, and Nebraska) from 2000-2006 using records taken from the National Climatic Data Center (NCDC) Severe Storms database. Patterns of interest include the seasonality of hail activity for each state and across the region, observational bias in the reporting of hailstone size, and temporal trends in the number of hail reports across the region and in each state. This paper then explores a …
