DESCRIPTION
TRANSCRIPT
Assignment To develop a few hypothesis about the
Fourmile watershed, in order to demonstrate our knowledge of Watersheds and water quality issues
Methodology
Day 1- Chemical Test Water Samples, Watershed Lecture
Day 2- Visited Big Darby Watershed, Ran Chemical Tests, Measured ICI And IBI. Demonstration Of Electro Fishing By Ohio EPA
Day 3- Model It (Independent Vs. Dependent Variables)Excel SpreadsheetsGathered Information About The Fourmile Watershed
Day 4- Learned Power Point PresentationCompared Fourmile and Darby Watershed on SpreadsheetsMade Three Hypotheses by Comparing Data to Station LocationMakes Graphs of the Data
Day 5- Presentation SkillsPower Point ProjectCreate Web SiteWomen of Achievement Panel
Day 6- Practice PresentationsComplete Web SiteComplete Power Point Project
Methodology 2
Definition Page 1
IBI = Index biotic integrity
ICI = Invertebrate community index
QHEI = Qualitative habitat evaluation index
DO = Dissolved Oxygen
TSS = Total Suspended Solids
Station ID = Number representing where the tests were done
Point Source Pollution = A known source of pollution
Non Point Source Pollution = An unknown but suspected source of pollution
Riparian Zone = A type of habitat associated with lush vegetation
Meander = a natural curve or turn in a creek or river bed
BOD = Biochemical Oxygen Demand
Definitions page 2
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

Hypothesis #3
Results
H1:The 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.
