This collection of four reports presents results of riprap stability studies conducted in the 8-ft-wide tilting flume at Colorado State University, Fort Collins, Colorado. The first three reports address stability of riprap on the bottom of the tilting flume using riprap having a wide range of thicknesses and gradations. The fourth report addresses the stability of riprap placed on a 1V2H side slope. Vertical velocity profiles were obtained at several positions across and along the flume to document flow conditions and flow rate for both stability and failure. Water-surface profile data were obtained to establish slope and channel depth along the flume. The hydraulic tests were conducted in an 8 ft wide, 4 ft deep and 200 ft long flume. The primary objective of this study was to test various sizes and roughness of riprap under different flow conditions to evaluate water erosion of the riprap along the bottom waters.
