Rydlund, Jr. Abstract Introduction Scour and depositional responses to hydrologic events Channel-bed dynamics of scour and deposition are have been important to the scientific community studying natural phenomena in alluvial systems in which bed and bank sediment transport as well as potential effects on bridges materials erode and re-deposit through the action of moving and other hydraulic structures within riverine systems. water. For a given hydrographic event, bed scouring is typi- A river channel-bed monitor composed of a single-beam cally observed on the rising limb of the hydrograph. At some transducer was installed on a bridge crossing the Chariton point beyond the peak of the hydrograph, deposition begins River near Prairie Hill, Missouri (structure L-344) as a to occur on the receding limb. The addition of a hydraulic pilot study to evaluate channel-bed change in response to structure, such as a bridge, exacerbates scouring conditions the hydrologic condition disseminated from an existing due to a change in flow area and
