Abstract
FLUME TESTS OF THE SCOUR-RESISTANT PROPERTIES OF A COMPOSITE SCOURINHIBITING MATERIAL ARE PROPOSED. THE MATERIAL IS MADE FROM GRAVEL AND CLAY. BY FILLING THE PORE SPACES IN THE GRAVEL, THE CLAY PREVENTS TURBULENT FLUID BURSTS FROM PENETRATING THE GRAVEL AND "SUCKING OUT" UNDERLYING BED MATERIAL. THE SCOUR INHIBITOR REMAINS PLASTIC AND FORMS A GRADATIONAL MARGIN BETWEEN ANY RIGID STRUCTURE AND A MOBILE BED. THE PROGRAM OBJECTIVES ARE TO OBTAIN: 1. A COMPARISON OF STABILITY BETWEEN THREE GRADED GRAVELS AND A COMPOSITE INHIBITOR MATERIAL MADE FROM THE SAME GRAVEL AND PURE CLAY. 2. DATA ON THE EFFECT OF GRAVEL SIZE ON THE STABILITY OF THE SCOUR INHIBITOR.
