Kentucky Lock Navigation Model

A 1:100 scale Navigation Model was constructed at the Waterways Experiment Station in Vicksburg, MS to investigate navigation conditions in the lower lock approach for a distance of two miles downstream of the dam. Construction of the model was completed in April 1999. The model includes a scaled version of the spillway, powerhouse and existing lock. Currently, base or existing conditions testing is ongoing. This information will be used as a comparison to conditions after the 1200’ Lock addition is in place. In addition to navigation, the model will be used to evaluate several environmental issues associated with the new lock and required railroad and highway bridge relocations.

Crews at WES prepare the Navigation Model for the new Lock by removing the existing topography and templates were the structure will be placed.

View looking upstream toward Kentucky Lock and Dam from a point approximately one mile downstream of I-24(prototype scale or fifty feet in the model scale). The color scheme is as follows: blue ranges from streambed up to elevation 302, yellow from 302 to 344 and green above 344.
