Many sedimentary systems include channelized bodies. These channels can be distributed randomly or can preferentially fill topographic lows at the time of deposition (termed compensational stacking). Exploring the stacking patterns of meter- to km- thick channelized packages from river delta to deep-water minibasins in six separate basins, award winner Kyle Straub and others (2009) described a suite of measurements that suggest that stacking patterns of channelized deposits are midway between the random and the compensational end-members. They interpreted the results to reflect that channel depth is a fundamental length scale that controls stratigraphic architecture across a range of depositional environments, and hence can be used to better constrain geologic models.
