Modifications to Filling and Emptying System of Lock No. 1, Mississippi River, Minneapolis, Minnesota =: Hydraulic Model Investigation

From abstract: The existing locks at Locks and Dam No. 1 were constructed between 1929 and 1932. Problems have been experienced with accumulation of ice and debris at the intakes, air entrapment in the culverts of the filling and emptying system, excessive turbulence in the lock chamber during filling, and hazardous conditions downstream from the locks during emptying operations.
