Navigation Locks: Navigation Lock Gates and Valves
Gates and valves for navigation locks are classified according to function as culvert valves, lock gates, or emergency closure gates. Model studies for McNary, Ice Harbor, Walter F. George,...

Length Of Culverts
An analytical solution for determining the length of culverts is presented. This solution is sufficient to provide the full width of the roadway or the width of the embankment at the top...

Hydrologic Design of Culverts
Simple and practical method is presented to determine peak discharge from small rural watersheds used in design of waterway openings of culverts or other small drainage structures; design...

The Contra Costa Energy Dissipator
Laboratory culvert outfall dissipator was developed for dissipator at Contra Coste, Calif, to provide rational procedure of design for installations that were to be adequate for prescribed...

Hydraulic Roughness of Corrugated Pipes
Original data on friction losses in two types of corrugated-metal pipes, obtained in the course of investigations into the hydraulic behavior of corrugated-metal culverts, are reported....

Prefabricated Reducers as Entrances for Pipe Culverts
Preliminary studies indicate that flow in reducer entrance will prime naturally; resultant sub-atmospheric pressures will become effective discharge energy, sufficiently high to establish...

Model Studies of Sector Gate Type Locks
Sector-gate system is used particularly where reverse head conditions might be encountered; model studies at Waterways Experiment Station have shown that in sector-type lock designs closing...

The American Locks of the St. Lawrence Seaway
Eisenhower and Grass River Locks have filling and emptying systems that utilize longitudinal culverts, side ports and tainter type valves; vertical lift gate provided at entrance to upstream...

Rigid Culverts under High Overfills

Free Outlets and Self-Priming Action of Culverts
Observation on scale models of culverts; effective position of hydraulic grade line at outlet section when outlet end of full flowing culvert is free from submergence; data on conditions...

Analysis of a Skew Diversion
Economic, hydraulic and topographical factors to consider in most economical location of culvert; culvert placed at reduced skew is chosen for analysis; result of analysis substantiates...
