ROCK MOVEMENT IN LARGE-SCALE TESTS OF RIPRAP STABILITY UNDER WAVE ACTION

THERE HAVE BEEN SEVERAL INSTANCES IN THE PAST FOUR OR FIVE YEARS, OF DAMAGE TO THE RIPRAP PROTECTION OF SOME EARTH DAMS AND EMBANKMENTS IN MAJOR RESERVOIRS IN THE MIDDLE WESTERN PORTION OF THE UNITED STATES. IN PARTICULAR, IN SMALL SECTIONS OF THE EMBANKMENT OF THE SNAKE CREEK SUB- IMPOUNDMENT IN THE GARRISON RESERVOIR IN NORTH DAKOTA, SOME RIPRAP WAS REMOVED BY A SEVERE STORM IN 1964. IT WAS RECOGNIZED AT THE TIME OF CONSTRUCTION THAT THE RIPRAP PROTECTION TO BE PLACED ON THIS EMBANKMENT WAS CONSIDERABLY LIGHTER THAN DESIRABLE, AND WAS KNOWINGLY PLACED AS AN EXPERIMENT TO SEE IF LIGHTER GRADED MATERIAL MIGHT STILL PROVIDE SUFFICIENT PROTECTION IN A RESERVOIR WHERE 32-MILE FETCH IN THIS AREA OF FREQUENT HIGH WIND VELOCITY. LOSS OF SOME RIPRAP IN THIS AREA HAS LED TO AN INVESTIGATION OF VARIOUS SCHEMES OF UPGRADING THE RIPRAP. AS A PART OF THIS INVESTIGATION, TESTS OF VARIOUS TYPES OF RIPRAP EXPOSED TO WAVE ACTION. HAVE BEEN MADE AT THE COASTAL ENGINEERING RESEARCH CENTER IN WASHINGTON, D. C. TESTS HAVE BEEN MADE AT BOTH SMALL AND LARGE SCALE. /ASCE/
