GEO 151 Geomorphology Term Project Presentation December, 2001 Performed and Presented by ……

This project analyzes the spatial variability of precipitation on Mount Mansfield in Stowe, Vermont. Data was collected using soup can gauges and shows a linear pattern of increasing precipitation with elevation. The results suggest higher rates of erosion and runoff in upper elevations, which should be considered in planning decisions for surrounding towns. Future considerations include using larger gauges and choosing more uniform collection sites.

  4. Spatial Variability of Precipitation on Mount Mansfield, Stowe, Vermont

  5. Methods • Collected precipitation using nine soup can gauges, constructed ourselves. • Designated an acceptable ridge on which to implement our gauges. • The chosen ridge was the Toll Road Ridge.

  6. Methods CONTINUED… • Collected data as often as possible between 10/27 and 11/17. Four sets of data were collected. • Attempted to avoid collecting during a precipitation event: avoid the skew of data. • Data collected in milliliters of water (samples often had to be melted for measurement).

  7. Precipitation levels collected by each Gauge, 10/31 trip.

  8. Calculations we used • (mL collected in graduated cylinder)(1cm^3/mL) = 1 cm^3 • 1mL = 1 cm^3 • (Volume Collected in Can) / (Can Orifice Area) = cm precipitation • (cm precip)(10 mm/cm) = mm precipitation • Can Orifice Area = 41.854 cm^2 • Short Calculation = (Volume collected) (0.2389258) = mm of Precipitation

  9. Summarized Project Data

  10. Snowpack on Mansfield

  11. What our data means… • Our data displays a linear pattern of increasing precipitation with elevation on Mt. Mansfield. • This increasing pattern of precipitation suggests higher rates of erosion and runoff for upper elevations than would be observed in valleys. • Erosion and runoff rates induced by precipitation should be considered in decisions concerning residential, commercial, and agricultural planning in the towns surrounding Mount Mansfield.

  12. Future Project Considerations • Use of larger gauges to prevent overflow. • Addition of synthetic oil to prevent evaporation and anti-freeze to prevent freezing. • Choosing more uniform collection sites to eradicate variability due to tree cover or overexposure to wind and sunlight.

  13. HIKED!!! We Climbed 11,080 Vertical Feet over a Span of 21 Days. This Project Required more Vertical Climbing than Required to Summit 14,410 ft Mount Rainier from its Base!!

  14. First run of the year –Halloween Night 2001

  15. Happy Birthday Big Boy
