Montgomery Point Lock and Dam Gate Study

Purpose: To determine the hydraulic loadings/ forces on the gated spillway. It was also used to evaluate the

hydraulic performance of the spillway, debris circulation potential downstream of the spillway and to design riprap

protection near the spillway.

Background: The proposed Montgomery

Point Lock and Dam will be located near the

mouth of the White River. This portion of the

White River is known as the White River

Entrance Channel, and is the initial segment

of the McClellan-Kerr Arkansas River

Navigation System. The project will consist

of a 670-ft long by 110-ft wide navigation

lock, a 300-ft wide controlled navigation pass

spillway, and a 200- wide fixed uncontrolled

overflow spillway.

Facts: At the request of the U.S. Army

Engineer District, Little Rock, a 1:15 scale

physical model was designed and constructed

at the U.S. Army Engineer Research and

Development Center by the Coastal and Hydraulics Laboratory. The model reproduces a three-gate section of the

navigable pass spillway and sufficient upper pool and tailrace length to reproduce prototype flow conditions near the

spillway. The model was used to evaluate the spillway gate design, provide hydraulic loadings for gate hoist

machinery and evaluate spillway performance.
