Design of Water Structures IHD 608 - Part I Quiz

Navigation Locks

• 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.

Navigation Lock Function

• 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.
