Item Hydraulic Stability of Channel LockTM Concrete Block Revetment System during Overtopping Flow(1996-09) Morgan, Scott; Toro-Escobar, Carlos; Voigt, Richard L. Jr.Item Hydraulic Stability of Conlock and Conlock II Concrete Block Revetment System During Overtopping Flow(St. Anthony Falls Laboratory, 1998-04) Voigt, Richard L. Jr.; Toro-Escobar, Carlos; Morgan, ScottThe St. Anthony Falls Hydraulic Laboratory (SAFHL) was contracted by Hydro-Turf & Associates to perform hydraulic testing of their Conlock and Conlock II concrete revetment systems. The testing was performed during February 1995 in SAFHL's largest flume, measuring 6 ft high x 9 ft wide x 253 ft long, with a maximum discharge capacity of 300 ft^3/s. The tests were undertaken to evaluate block performance to provide information regarding failure thresholds under controlled laboratory conditions. The testing was conducted in a manner to replicate as close as practical, the testing performed by Simon's, Li and Associates, Inc., for the Federal Highway Administration's overtopping embankment studies. A detailed description of the test setup is included later in this report. The embankment was constructed at the downstream end of the channel, extending into the tailgate pit. This allowed construction of an embankment 5.5 ft high and a maximum overtopping depth of 3.5 ft. The 3:1 downslope followed a 20 ft level section; both the embankment and level section were installed to the full 9 ft width of the channel. The full width was chosen to minimize sidewall effects.Item Velocity, Rapid Drawdown and Wave Testing of Prototype Anchor Vertica Units(St. Anthony Falls Laboratory, 1995-05) Voigt, Richard L. Jr.; Erickson, Benjamin; Morgan, ScottThe St. Anthony Falls Hydraulic Laboratory (SAFHL) was contracted by Anchor Wall Systems, Inc. to perform hydraulic testing of its Anchor Vertica units. The testing was performed during March and April of 1995 in SAFHL's largest flume, measuring 6 ft high x 9 ft wide x 253 ft long, with a maximum discharge capacity of 300 ft^3/s. The tests were undertaken to evaluate Vertica block performance when subjected to conditions which may be encountered in channel and shoreline applications. This report describes the test procedures and technical data obtained during the testing of the Vertica units. As such this report provides background for a video produced by Promotovision entitled "Anchor Keeps the Water Away." Two different test walls were constructed to evaluate three potential mechanisms which could lead to possible failure. 1. Wall performance when subjected to high velocity water flowing past a channel wall entrance and passing along a channel side wall. 2. The effects of rapid drawdown on a wall under saturated backfill conditions. 3. The effects of repeated wave impact on wall performance
