This report presents results of tests to investigate the effect of the relative position of the filling valves and port manifold on lock filling characteristics in a sidewall port system for a 110- by 1200-ft lock. These tests are supplemental to generalized tests on a lock of this size (Cannelton Main Lock, Ohio River). Pressure and flow distribution data revealed that the most upstream port in the manifold must be at least 6.5 times the culvert height downstream from the filling valve in order to have this port out of the low pressure zone created by the valve. However, with as many as four ports in the low pressure zone no differences in filling time or hawser stresses could be detected from those obtained with the entire manifold downstream from the low pressure zone.
