12	Derive the unit conversion factor C in the following formula: Qs = C Cs Q in which Qs is given in kilonewtons per day, Cs in milligrams per liter, and Q in cubic meters per second.	201203	201210
11	What is the difrerence between the following forms of scour: (1) general scour; (2) contraction scour; (3) clear-water scour; (4) live-bed scour; (5) local scour; and (6) lateral migration. Explain in detail.	201124	201203
10	Why is a sediment retention basin likely to be a counterproductive measure to control sediment in alluvial streams?	201119	201201
09	How is the presence of bedforms reflected in the shape of a sediment rating curve? Explain in a 100-word statement.	201105	201112
08	What is the d84? Why 84? Why is it used in sedimentation engineering, in addition to the mean particle size d50, to characterize roughness in sand-and-gravel-streams? (See Ponce: Open-channel Hydraulics, Chapter 5, Manning formula).	201015	201022

06	Do the levees on the Lower Mississippi river decrease or increase flood hazards in the long-term? Explain in a 200-word statement, using concepts of hydraulics, hydrology, geomorphology, and sediment transport.	201001	201008
05	How does baseflow loss increase sediment transport? Explain in a 100-word (or less) statement.	200922	200929
04	Why is sediment yield always less than sediment production? Explain the physical and geomorphological process in a 100-word statement.	200915	200922
03	Would Kennedy's principle (in A15) apply to all rivers, or would there be some exceptions? Explain in a short statement.	200908	200915
02	Derive Eq. 13-2 in A02 of the syllabus.	200901	200908
