Presentation Transcript

  1. Hydrology Site Definition and Mapping Your Site

  2. Site Selection • in order of preference • Stream or river • Lake, reservoir, bay, or the ocean • Pond • Irrigation ditch or other (if none of the above is available)

  3. Preparing For Your Measurements • Once your site has been selected, "Define Your Site" using the Documenting Your Hydrology Study Site Field Guide and Mapping Your Hydrology Study Site Field Guide. • If possible, conduct your Hydrology measurements weekly. • All measurements should be made at roughly the same time of day.

  4. Quality Assurance and Quality Control • Collect the water sample as directed. • Perform most tests immediately after collecting the water sample (see protocols). • Carefully calibrate, use, and maintain all testing equipment. • Follow the specific directions of all protocols EXACTLY as described. • Repeat measurements to check their accuracy and understand potential sources of error. • Minimize contamination of stock chemicals and testing equipment.

  5. Why map your site? • Without a study site definition, it is difficult for you or scientists using your data to interpret your data for scientific research. • To describe your study site, follow the instructions in the Documenting Your Hydrology Study Site.

  6. Include on map… • Name of site • Name of water body, for example, Platt River • Direction of North (use arrow) • Scale (indicates distance, e.g., 1 cm = 3 meters) • Date • Key to all symbols used in map

  7. While making your map… • Look around, what things might be influencing the characteristics of the water? • What would you like to know about the water? • Think of one or more research questions about the water at this site.
