1 GS407-507 GIS Applications in Earth Sciences End-of-Workshop Project DUE: Monday June 27, 2005 Your job is to compile a complete set of GIS vector map themes, digital elevation models, and DRG’s for a select watershed in western Oregon. In addition you will calculate some basic watershed parameters from your GIS compilation. _________________________________________________________________________________________ Student Assigned Coast Range Watersheds Kari Carr 1. Gales Creek Watershed (Tualatin Basin, Washington County) Jeff Kent 2. Elk River Watershed (Sixes River Basin, Curry County) Katie Noll 3. Calapooya Creek Watershed (Umpqua Basin, Douglas County) Dane Wagner 4. Schooner Creek-Drift Creek Watershed (Siletz-Yaquina Basins, Lincoln County) Instructions: All final project materials will be included at the end of your portfolio binders Make sure you organize your final projects by Task No., and clearly label the sections in order of appearance below. Task 1. Using the Coast Range Watersheds theme from the class website (under the final project section), find all of the subbasins that are contained within your assigned watershed. Task 2. Identify the County(ies) in which your watershed (and related subbasins) is (are) contained. Task 3. Identify all of the USGS 7.5-minute quadrangles that contain portions of your watershed. Task 4. Using ArcView, select your watershed sub-basins from the Coast Range Watershed theme and convert them to a new, stand-alone shape file. Task 4A. Create a map layout, with name, title, scale, north arrow, legend, etc. Print your new watershed subbasin theme map. Task 5. Using ArcView, dissolve your sub-basin polygons into one large watershed polygon for your study site. Task 5A. Create a map layout, with name, title, scale, north arrow, legend, etc. Print your new consolidated watershed boundary theme map. Task 6. Using ArcView and the 1:24000 State Quadrangle polygon theme from the class web site (under the final project section), select all of the quads that contain your watershed footprint. Convert the selected quadrangles to a new, stand-alone shape file that can be used as an overlay on your watershed footprint. Task 6A. Create a map layout, with name, title, scale, north arrow, legend, etc. Print your new quadrangle map with watershed footprint overlay. Task 7. Using ArcView and the “Coast Range Streams” theme from the class web site (under the final project section), clip the stream coverage so that it forms an overlay within your watershed footprint. Task 7A. Create a map layout, with name, title, scale, north arrow, legend, etc. Print your new watershed footprint theme map with stream pattern overlay.2 Task 8. Use the ArcView table manager and your newly created watershed themes to determine the following watershed parameters: Total Drainage Area (sq. meters) _________________________ Total Drainage Area (sq. km) _________________________ Total Length of Watershed (sq. km) _________________________ Total Width of Watershed (sq. km) _________________________ Watershed Length/Width Ratio _________________________ Total No. of Subbasins in Watershed _________________________ Average Area of Subbasins in Watershed _________________________ Total No. of Stream Segments or Tributaries in Watershed _________________________ Total No. of First Order Stream Segments _________________________ Total No. of Second Order Stream Segments _________________________ First Order Stream Frequency (Total No. / Drainage Area) _________________________ Task 9. For your selected watershed, use the GIS web links on the class web site (plus any others that you may find) to download and assemble the following GIS themes: USGS DRG (raster) Soils (vector) USGS DEM (raster) Vegetation (vector) Bedrock Geology (vector) Roads (vector) City Boundaries (vector) Streams (vector) Parameters: 9-1. convert all map themes to UTM meters, Zone 10 North (NAD_1927) 9-2. Clip each vector file so that each theme perfectly overlays the watershed boundary footprint. 9-3. Using layout with student names, quadrangle name, map theme title, scale, north arrow, legend, print the following and assemble in a neat looking package to include in each of your portfolios: Printout for each watershed A. Quad DRG’s D. Soils on DEM G. Cities on DRG B. Quad DEM’s E. Bedrock on DRG’s H. Streams on vegetation C Vegetation with polygons labeled F. Roads on bedrock Task 10. Using the class web site resources and download links, find and assemble all of the Digital Orthophoto Quads for your watershed (Mr. Sid files are the most compact and easiest to use). Using layout with student names, quadrangle name, map theme title, scale, north arrow, legend, print the DOQ’s to include in each of your portfolios.3 Task 11. save and assemble all of your data and project files on a CD to submit with each of your portfolios, respectively Task 12. Using ArcView Spatial Analyst, your assembled DEM’s, and watershed themes, calculate the following watershed parameters: Minimum Watershed Elevation (feet) _______________________ Maximum Watershed Elevation (feet) _______________________ Minimum Slope (decimal degrees) _______________________ Maximum Slope (decimal degrees) _______________________ Task 13. Copy/Save/Compile all of your GIS themes, shapefiles, grids, and raster graphics onto a CD. Organize your data folders according to projection and theme topic. Include an MS-word document that provides a list of the GIS files you have compiled, a brief explanation of what the files are comprised of, and a list of projections. This word document will serve as your
