  Unit III Data Collection

 

MODULE 7 WATERSHED/LANDUSE SURVEYS

• Introduction to Watershed Assessment (check out www.watershednet.com/manual.html)
• Public surveys—question formulation, survey instruments and design
• Identification of watershed issues
• Historical conditions assessment
• Landscape characterization
• Channel habitat type classification
• Hydrology and water use
• Riparian/wetlands assessment
• Sediment sources assessment
• Channel modification assessment
• Watershed characterization of temperature
• Watershed condition evaluation

MODULE 8 LAKE SURVEYS - Field

• Lake morphometry

- graphical (planimetry, count the squares, cut and weigh)
- software (GIS and simpler programs)
- manual and acoustic depth sounding


• Physical and chemical field profiling

- Temperature, DO, pH, EC, redox (including calibration and maintenance)
- In-situ instruments (data logger calibration and maintenance – SEE MOD 12)
- Light (Secchi; radiometers)

• Sampling

- Conventional (Van Dorn, Niskin, bottles, pumps)
- Contaminants (clean techniques)
- Microbes (sterile technique)
- Water sampling – automated
- Zooplankton (e.g., nets, traps)
- Benthos and sediments (e.g., cores, dredges, traps)
- Aquatic vegetation (e.g., visual; grabs; census transects; wetland delineation)
- Fish and fish habitat assessment (e.g., seines; traps; acoustic)
- QA/QC

MODULE 9 LAKE SURVEYS - Laboratory

• Bottle preparation
• Water quality analyses (basic)

- Alkalinity, hardness
- TDS, salinity, EC, color
- TSS, turbidity
- Nutrients (N and P – principles of colorimetry)

• Water chemistry kits
• Microbiology (e.g., fecal coliform. E.coli)
• Specific ion probes (e.g., chloride, ammonium)
• Ions (IC, AAS overviews)
• Chlorophyll-a (extractions; spectrophotometric and fluorometric methods)
• Phytoplankton assessment (rapid scans; quantitative microscopy)
• QA/QC

MODULE 10-11 STREAM SURVEYS

• Water quality assessment
• Field instrumentation (WQ meters, flow metering, data loggers)
• Water sampling (USGS Manual methods; pumps; remote samplers)
• Organism collection
• Biotic parameters

- Rapid bioassessment protocols for wadeable streams (www.epa.gov/owow/monitoring/rbp; physical, chemical, and biotic characteristics)

• Fish and fish habitat assessment (e.g., seines, traps, acoustic)

MODULE 12 REMOTE SENSING AND INTERNET DATA SOURCES

• Satellite and aircraft imaging
• Satellite and aircraft sensors
• Automated in situ data loggers, samplers and modems (e.g., YSI, Hydrolab, RUSS)
• Sonar, hydroacoustics
• Radar
• Federal databases (e.g., STORET, BASINS, USGS)
