Book Description
A mathematical model called SOCHMJ (Simulation of Open Channel Hydraulics in Multi-Junction Systems) was used to determine the effect of valley storage loss in the Cannelton Pool on flood heights along the Ohio River. Three levels of storage loss have been investigated. The first level was the complete removal of valley storage and was accomplished by assuming the placement of levees along the banks throughout the Cannelton Pool. The second level of storage loss was arrived at through placement of levees halfway from the bank to the maximum lateral encroachment of the 1945 flood throughout the Cannelton Pool. The third level consisted of assuming levees along the bank of the lower 58 miles of the Cannelton Pool. For each of the first two levels of storage loss, the calibrated values of Manning's n throughout the Cannelton Pool were first increased and then decreased by 20% to determine the effect on flood heights of varying the roughness coefficient. It is concluded that, before initiating major floodplain encroachment in the Cannelton Pool, additional studies with a much more elaborate treatment of the flows cutting across major river bends should be undertaken.
