ES322 Geomorphology Fall 2006 Final Study Guide NOTE The final exam is schedule for 12 00 2 PM on Tuesday Study Tips complete all labs and worksheets before exam use study guide in combination with notes go back through the in class lab exercises make sure you can work the math units spend a couple days studying the exam will be essay and there is much material don t wait until the last minute carefully go through the notes some of the material we briefly discussed but did not spend much time on in class but the notes will give you the detail Exam Procedures 1 Final exam will be 120 points 2 Part 1 essay questions focusing mainly on material since mid term but with a limited number of comprehensive questions covering material prior to the mid term See key word recommendations below 3 Part 2 Open Book lab style quantitative questions map questions air photo questions identification of fluvial coastal landforms identification of basic climatic geomorphic features Association of landforms with processes Bring a calculator Keywords To Focus On Since the Mid Term Fluvial Hydrologic Cycle Water Budget Discharge precipitation infiltration intensity recurrence interval width depth

calculations field data collection be able to interpret relationships between tectonic uplift and global sea level change can you identify which process is affecting a given sea level record how has global sea level changed during the late Quaternary and why make sure you can calculate slopes and gradients from topographic maps can you plot a ternary diagram using soil texture data can you determine the recurrence interval of a given flood discharge how about solving hydraulic flow problems using Manning s Equation and the Continuity Equation what is the relationship between river load type of sediment and river morphology can you identify landforms geologic processes from air photos could you identify stream drainage types dendritic trellis radial etc from
