AB - A commonly used approach to evaluating the potential for internal instability in soils is that of Kenney and Lau. This method involves a shape analysis of the grain size curve over a length of the soil’s finer part. A soil that is internally unstable has a particle size distribution with a finer frac- tion less than the coarser fraction; therefore, the coarser fraction makes up the primary fabric of the material. Thus, the fine-grained particles are loose (non-structural) in between fixed (struc- tural) coarser grains, and these loose fine particles are permitted to migrate through the constric- tions of the fabric of the coarser fraction. This paper discusses the evolution of the Kenney-Lau method and its boundary relations, and furthermore, a discussion on adaptations of the method, which touches on field experience and engineering practice, is given. Keywords Internal Stability, Internal Erosion, Granular Soils, Filters, Kenney-Lau Method 1. Introduction Normally, a soil comprises particles of different sizes. The relative amount by mass contributed by these par- ticles defines the grain size distribution (i.e., grading) of the soil. A soil spread over a wide range of particle siz- es is considered widely graded, whereas a grading containing few fractions is
