1G473 Environmental Geology Spring 2001Final Exam Study Guide - Key Terms and Concepts Since Mid-Term(1) Student PresentationsTectonic Setting of PNW (Todd)Keywords: subduction zone, volcanic arc, western Cascades, High Cascades, eastward arc migration,Juan de Fuca plate, North Americal plate, early Tertiary western Cascades, Pleistocene High CascadesvolcanismExample Concept Question: Discuss in detail the plate tectonic setting of the PNW. Include a cross-section and map showing the key elements.Seismic Hazards PNW / Oregon (Harper / Utley)Keywords: crustal deformation, intraplate faulting, active faulting, neotectonics, coastal uplift, plateflexure, tsunami, tsunami deposits, tidal muds, tsunami sands, buried forests, neotectonic subsidence,earthquake recurrence interval, radiocarbon dating, Basin and Range faulting, crustal stressExample Concept Question: Discuss earthquake hazards in the PNW. In your discussion include theplate tectonic setting and driving mechanisms for earthquakes. Draw a cross-section showing a typicaltsunami cycle and discuss the concepts of paleoseismology and what is known about seismicrecurrence interval in the PNW.Volcanic Hazards PNW (Christiansen, Parker, Hunt, Spradley)Keywords: lahar, pyroclastic, tephra, ash, blocks/bombs, explosive volcanism, catastrophic outburstfloods, lava flows, glacial melting / lahar processes, Mt. Rainier, Mt. Jefferson, Newberry, Mt. Hood,lahar runout zoneExample Concept Question: Discuss volcanic hazards of the PNW in the context of plate tectonicsetting. Use cross-sections to illustrate the relationships. Define and discuss the types of volcanichazards associated with the Cascades. Include types of eruptions, products, and hazards. Whichvolcanic areas in the PNW pose the greatest risks and why?Willamette Valley Environmental Quality (Sexton, Whiteley)Keywords: land use, agriculture, grass seed industry, lumber processing / treatment, pesticides /herbicides, surface discharge, shallow groundwater quality, industrial processing, industrialcontaminants, sewage effluent, Willamette basin environmental qualityExample Concept Question: List and discuss the environmental quality issues associated with theWillamette basin. Include in your answer: land use, types of contaminants, pathways for contaminantmigration, and risks to the ecosystem.2(2) SpeakersGordon Grant / DamsKeywords: dam, reservoir, upgradient environment, downgradient environment, flood control,recreational use, dam removal, "blow and go", incremental removal, knick point, erosion, deposition,salmon issues / spawning habitat, symbolism, conceptual model, research design, sediment transportmodelKatzman / LANLKeywords: LANL, manhattan project, outfall, radioactive isotopes, sediment transport, watershedapproach, conceptual model, geomorphic mapping, fine grain vs. coarse grain sediment, fire, ash,background global radiation, above-ground testing, fire concentration of isotopes, floods, hillslopeerosion, contaminant migration.Panek / Overview of Groundwater AssessmentKeywords: groundwater assessment, monitoring wells, groundwater remediation, pump-and-treat,activated carbon, creosote contamination, DNAPL, bioremediation, natural attenuation, groundwaterhydraulics, groundwater flow, upgradient, downgradientShump / Groundwater Assessment - RemediationKeywords: groundwater assessment, natural attenuation, tidal fluctuation, groundwater fluctuation,upgradient / downgradient, risk to environment, shipyard contamination, EPA, client, consultingphilosophy(4) Mountain Fir / Groundwater LabKey skills: plotting a groundwater elevation map using surfer, basic data analysis with excel, plotting acontaminant plume map using surfer, evaluating groundwater quality data, identifying upgradient anddowngradient hydrologic regimes, identifying shallow and deep aquifer systems, distinguishing betweenconfined and unconfined aquifers, interpreting a drillers log / well installation
