re: patience on morganza

the power of the flow comes from the height differential. if there is 4 feet between the miss and the spillway, you get that sort of falling power. if the height is greater, you get exponentially more power. if the river is allowed to silt on the other side of the morganza spillway, you reduce the effectiveness of it with each foot of sedimentation allowed in the first couple of miles from the river. when you release the beast, you solve the sedimentation problem for many miles and for at least this year's flood (not to suggest it won't cause problems in the flood of 2015).
