This correspondence course concentrates on the theory and application of water temperature modeling. Participants will develop knowledge of stream geometry, hydrology, and meteorology to enable understanding and prediction of stream temperatures. Topics covered include the models' assumptions and limitations, calibration and verification, troubleshooting, field data collection, parameter estimation, handling missing data, quality control, reviewing a completed temperature study for quality assurance, and linkage to other IFIM programs. Hands-on exercises are used to reinforce concepts learned in lectures. Participants will be supplied with all relevant models and material that they will complete at their own pace. An instructor will be available by phone or E-mail for individual questions with a final exam gauging successful completion of the material.
Individuals directly involved with computer modeling of stream temperatures, including ecologists, fishery biologists, and hydrologists, or anyone who regularly comments on proposed changes in water project operations or helps in designing impact evaluation studies.
Upon completion of this course, participants will be able to:
- Understand the theoretical basis for the models including their assumptions and limitations.
- Be fluent in the stream geometry, hydrology, and meteorology components of the models, and how combining these components create a stream system description.
- Understand how to enter data, run, and interpret results from the network and stream reach versions of the models.
- Be capable of calibrating the models given typical constraints, e.g., some data are missing.
- Be capable of using the models to estimate unknown temperatures in a baseline condition and predict water temperatures under altered conditions.
1. Conduct a "live" temperature investigation, including how to plan a cost-effective study, gather needed input data, assemble that data into appropriate formats, and display results in a communicative manner;
2. Review a completed study, performed by another individual or organization, to assure its quality by critically analyzing the modeling components and evaluating the achievement of study objectives.
Approx. 30-50 hours, self-paced.
