 | This Coastal and Hydraulics Engineering Technical Note (CHETN) demonstrates the construction of a three-dimensional (3-D) computational flow model of a lock filling system. A numerical flow model capable of simulating flows in navigation locks will provide an economical tool for detailed evaluation of locks and lock components. A description of the construction, implementation, and evaluation of a 3-D model of a lock filling system is presented. Computational and hydraulic engineering ... |

|
| This Coastal and Hydraulics Engineering Technical Note (CHETN) demonstrates a means of calculating hydraulic forces acting on submerged surfaces of hydraulic structures. The primary concern in evaluating the hydraulic performance of a structure is whether it can withstand the imposed hydraulic forces. Forces acting on components such as stilling basins, spillway faces, bridge piers, culvert valves, spillway gates, lock guard walls, floodwalls, etc., must be accurately estimated to ensure appropriate ... |

|
| The U.S. Army Corps of Engineers, Huntington District (LRH) has been charged with upgrading Dover Dam to meet hydrologic design standards and address stability issues. The LRH requested that the U. S. Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory (CHL), evaluate the flow conditions in the Tuscarawas River downstream of Dover Dam as part of a safety assurance program. The two-dimensional depth-averaged module of the Adaptive Hydraulics ... |

|
| A numerical model study of the Hoosic River Flood-Control Channel was conducted to determine the flow conditions with the channel as it presently exists as compared with the as-built conditions. Sediment has accumulated in certain portions of the channel resulting in relatively large areas of deposited material that may inhibit flood-flow conveyance. The two-dimensional depth-averaged module of the Adaptive Hydraulics (ADH) finite element flow solver was used to obtain velocity ... |

|
| The critical hydraulic configuration for a set of torque-tube gates controlling the flow through the navigable portion of a spillway was experimentally identified. In this paper, an analytical model for the upstream pressure field on a typical gate within the set is constructed. The gate rotation from the maximum elevation gate in closed position and the hydraulic torque transmitted by the pressure field to the gate tube are formulated. Mean ... |

|
| This report presents a review of design guidance and hydraulic parameters associated with lock culvert valves. Many locks are beyond their design life, and the filling- and emptying-culvert valves are being replaced to keep the lock in service. Valve selection has begun for several new locks and lock extension projects. This report provides general information on three valve types: vertical lift, conventional tainter, and reverse tainter valves. The positive and ... |
