CIVE 413 ENVIRONMENTAL RIVER MECHANICS Pierre Y Julien April 21 2008 Sample Review Problems on River Engineering 1 Consider a large river during a ood The main channel width is 250 m the ow depth is 662 m and the flow velocity is 226 ms The channel slope is 10 cmkm and the grain diameter is uniform 025 mm sand Determine the following the F roude number Manning n the bed shear stress the Shields parameter what particle diameter is at beginning of motion what is the settling velocity of the bed material what is the shear velocity of the ow is most of the sediment transported as bed load or in suspension 9 09 rm 90 575 2 Bridge piers are built on the river discussed above The type of bridge pier considered is a square concrete bridge pier 35 m wide Determine the scour depth around the structure Also estimate the angle of repose of the material and estimate the lateral extent of the scour hole 3 Repeat the calculations from 2 above for the case of replacing square bridge piers with a large round sheet pile caisson that is 152 m in diameter Determine the scour depth and the lateral extent of the scour hole 4 The engineers are also considering an abutment protruding into the river Consider a 75 m long spill through abutment that is normal to the main ow direction Also consider a 50 m abutment with the same orientation angle with vertical sheet pile wall at the end of the abutment Compare the abutment scour depths for both cases 5 The median particle size distribution of riprap is 500 mm Determine the proper particle size distribution ofthe riprap if is it placed on the sand bed channel Would a single filter be suf cient Plot the particle size distributions and determine the particle size distribution of the lters Whig 0720m5 973 W QM52 WMMDVZ V22 R235 V2 lQ7
