Vernaza, Ph.D. Gannon University, Erie, PA Regional Science Consortium 8th Annual Research Symposium

2. History of the Scholarship • Scholars of Excellence in Engineering and Computer Science (SEECS) • NSF, Directorate of Undergraduate Education • Scholarships in Science, Technology, Engineering and Mathematics (S-STEM) • Grant of $600,000 awarded in July 2008 • 11 graduates of the program, to date • 26 current SEECS scholars: five seniors, six juniors, seven sophomores, and eight freshmen • Renewal awarded in May 2012 for $600,000 8th Annual Research Symposium

3. Background • Creeks are becoming polluted • Debris, Toxic contaminants, etc. • Pennsylvania Sea Grant (Non-profit Organization) • - “Promotes the ecological and economic sustainability of • Pennsylvania's coastal resources through research and outreach … focusing on the Lake Erie and Delaware River drainages of Pennsylvania” • - Partnered with Gannon University SEECS program • - Tasked with building a sediment collection device 8th Annual Research Symposium

4. DESIGN Constraints • The device to be prototyped and constructed should meet the following constraints: • Collect two (2) liters of wet sediment • Environmentally friendly • Movable by one person • Under SEECS budget • Anchored in place • Durable and reusable • Collect sediment of different sizes 8th Annual Research Symposium

5. OUTLINE: DESIGN AND BUILDING PROCESS (‘10-’12) • Toured Cascade Creek • Researched methods of sediment collection • Designed, built and tested two prototypes • Combined and optimized initial designs • Constructed final product • Implemented sediment collection device 8th Annual Research Symposium

6. Research • Initial ideas • Pump water out of creek to a filter • Modified downstream defender • Use bedload sampler 8th Annual Research Symposium

7. Sediment Collection Device: • Two designs were prototyped and tested Design 1 Design 2

8. RESULTS OF Weir Tank TESTING Design 1 Design 2 Confetti was employed to simulate sediment. Results were positive. 8th Annual Research Symposium

9. Sediment Collection Device: • Designs were consolidated and collector built Frame Back Box Front Box

10. Frame Dimensions • 4 feet long by 2.5 feet wide • 13 inches tall • 8 inch platforms on sides • Lid with latches • Concrete blocks set on sides • Held in place by L brackets 8th Annual Research Symposium

11. Box Dimensions • Two boxes • 18” long • 12” tall and wide • 8” wide by 5” deep opening • Screen at front and back openings • First Box • Four baffles • Second Box • Three baffles • Elbow joint at exit 8th Annual Research Symposium
