Name: ______________________ RED ID: __________________ Grade: _______

Instructions: Closed notes, turn off cell phones. Answer each question in a clear and concise paragraph. Use engineering paper.  Answer only 10 questions.


  1. Explain how the increase in flood magnitude and the drying of springs are related.

  2. Why is baseflow recession better than pump tests to assess regional aquifer characteristics?

  3. What is the major difference between the NRCS and Snyder synthetic unit hydrographs?

  4. Are plants in arid regions in competition with groundwater well usage? Explain.

  5. What was the primary contribution of the Creager curve?

  6. What is the difference between the original Clark unit hydrograph and Prof. Ponce's version? Which method gives a slightly higher peak? Why?

  7. Why did Woolhiser and Liggett switched their research emphasis from dynamic to kinematic wave modeling in the mid 1960s?

  8. State three differences between the Muskingum and Muskingum-Cunge methods of flood routing.

  9. In dynamic wave routing, how is the lack of a suitable dynamic downstream boundary condition resolved in practice?

  10. Why is the usage of HEC-RAS dynamic wave routing not advisable for stage design in channel improvement projects?

  11. How does global warming affect hydrologic practice? In snowcaps? In glacier melt hazards? In flood frequency? In sea level?

  12. How does permanent indirect artificial combustion (PIAC) (the paving of formerly naturally productive land) affect global warming? What percentage of the problem do you estimate may be attributed to PIAC?
