    Study Notes

    • The purpose of extending side culverts through a landing wall to form cross culverts at equal distances is to facilitate the filling or emptying of a lock chamber.

    Time Variables

    • 't1' represents the time taken to fill or empty a lock chamber.

    Lock Gates

    • Sluice gates installed in lock gates are used in addition to another feeding system to control the flow of water into or out of the lock chamber.

    Water Conservation

    • Water conserving basins are used to conserve water in the context of lock chambers.

    Lock Chamber Dimensions

    • The minimum depth of water in the lock chamber is not specified in the given data.
    • The function of Navigation Locks is to raise or lower vessels between two levels of water.

    Feeding Systems

    • One type of Navigation Locks feeding system NOT mentioned in the text is not specified.

    Vessel Dimensions

    • Common vessel dimensions mentioned in the text are not specified.

    Side Culvert Feeding

    • Side Culvert feeding exists in the system where water is drawn from the upper pool and fed into the lock chamber.

    Regulator Function

    • The purpose of a Regulator in relation to a Navigation Lock is to control the flow of water into or out of the lock chamber.

    Structural Calculations

    • The formula e = tw/2 – x is used to calculate the thickness of the lock chamber wall.
    • The formula X = Mo/tw is used to calculate the bending stress in the lock chamber wall.
    • The formula f = - N/tw(1 ± 6e/tw) is used to calculate the shear stress in the lock chamber wall.
