Grain-size analysis can be useful in determining some of the hydrodynamic aspects of the evolution of a natural sand body. The suite statistics approach minimizes single-sample anomalies and provides detailed statements about the transport agency. Linear suite data (e.g., old to young) may provide information on shifting conditions. Using both of these, plus a few single sample parameters, one typically can identify transport agency, maturing of the sand pool, introduction of a new sand source, change in sea level, direction of change, shift in energy level, and, in some cases, identity of the 'last previous' agency. In each instance, a specific hydrodynamic effect is identified.
