This short course provides a comprehensive review of quantitative reactive transport modeling in geological and environmentally sensi- tive systems. Emphasis will be on: (1) presenta- tion of the governing physical and chemical equations, and (2) the practical application of this theoretical frame- work. The course will also include a one-day computer software jamboree at the Colorado School of Mines to allow for practical, hands-on instruction in the use of publicly available geochemical and biogeochemical modeling codes. Applications will illustrate coupling kinetically controlled water-rock inter- action, solute speciation, and biological activity with advective-dispersive-diffu- sional transport in fluid phases to solv- ing real geochemical transport problems ranging from environmental waste transport to metamorphism.

End-of-Program Assessment in Geoscience Departments. Sunday, October 27, 1:00 to 5:00 p.m.; Colorado Convention Center. Sponsored by GSA’s SAGE Program. End-of-Program Assessments are a feedback mechanism to help a faculty answer the question: Does our educa- tional program produce the results we are seeking? The answer is then used to improve the program. Participants will study examples of various assessment methods. Experience with assessments is not required. Participants who bring departmental information will plan assessments, or improve assessments, for their departments. Black Canyon of the Gunnison outside Gunnison, Colorado. Photo by Mark A.
