Steady State Overtop Testing – Simulated Heavy Debris Loading

Once the hydraulic jump testing was complete, testing was performed to simulate heavy debris loads on the installed HydroTurf® Revetment System that had already been tested for over 16 hours.  The purpose of this test was to qualitatively assess the resilience of the HydroTurf System to impact and abrasion from large debris.

The flow in the flume was brought to an overtopping depth of 5.0-ft.  A Bobcat S850 front-end loader was filled with broken, angular concrete blocks ranging from approximately 3 to 15 inches in diameter.  Two (2) bucket loads from the Bobcat were dumped into the flume at the top of the embankment from a height of approximately 12 feet.  No instability, loss of intimate contact, or erosion was observed as a result of this heavy debris loading.
