May 2002 Flood Photos - More flood data will be added later.Velocity and flow data was collected on 22 May, 2002, with an Acoustic Doppler Current Profiler.After the data is processed and analyzed, the information will be presented here.Click on the individual thumbnail images for a full size view.Aerial photography will also be available soon:

Project Description: From River Mile (R.M.) 7.0 above the confluence with the Ohio River at Cairo, to R.M. 24.0, the Mississippi River flows in a broad sweeping reverse curve. The distance is about 17 river miles; the average gradient is about foot per mile. The narrowest distance across the neck of the large meander loop, an agriculturally rich 10,000-acre land mass known as Dry Bayou-Thompson Bend, is just 1 miles. Given the close proximity of the confluence, flooding across this area is incredibly erratic.The River can run virtually backward a high Ohio River backing up a low Mississippi. Or it can be viciously swift a high Mississippi rushing to a low Ohio. The Great Flood of 1993 presented the worst example of the latter scenario. With a 14-16 foot gradient across the narrow neck of alluvial floodplain, massive erosion and scour could potentially destroy thousands of acres of valuable farmland, create a disastrous Bendway Cutoff, and erode a section of the Commerce/Birds Point Mainline Federal Mississippi Rivers and Tributaries (MR&T) Levee................click here to read the rest of the description.....
