Prototype Filling and Emptying System Measurements, New Bankhead Lock, Black Warrior River, Alabama.

Abstract

Prototype studies were conducted to measure pressures in the filling and emptying culvert system and to monitor various other parameters relating to the operation of the new John Hollis Bankhead Lock. Air demand downstream of the filling valve was studied as related to low pressures in the culvert. Measurements at some points in the culverts indicate that pressures existed at or near the vapor pressure of water for certain test conditions. Prototype data are compared with math model computations for piezometric head downstream of the filling valve, valve well water-surface elevation, and lock water-surface elevation. This comparison revealed generally good agreement. (Author)
