Assignment

• To develop a few hypothesis about the Fourmile
  watershed, in order to demonstrate our knowledge
  of Watersheds and water quality issues

Variables) Excel Spreadsheets Gathered
Information About The Fourmile Watershed

Hypothesis

• H1 When the QHEI (Qualitative Habitat
  Evaluation Index) increases, the ICI
  (Invertebrate Community Index) and the IBI (Index
  of Biotic Integrity) increase
• H2 The closer the creek is to the city the lower
  the ICI and the IBI
• H3 The TSS (Total Suspended Solids) increases in
  agricultural areas

Results

• H1The hypothesis is correct. When the QHEI
  increased the ICI and IBI increased.
• H2 The hypothesis is correct. Due to the
  location of an urban setting the ICI and IBI
  levels decrease near the city and increase near
  the rural areas.
• H3 The hypothesis is correct. This hypothesis
  was also based on location and the TSS level was
  higher if it was near a rural area, rather than
  an urban area.
• Refer to map of Station I.D.(111-116)

Conclusion

• We tested our hypotheses and we concluded that,
  according to our research, our hypotheses were
  all correct.
• All of our graphs based on our research showed
  that we came up with the correct hypotheses about
  our watershed.
