INTRODUCTION The analyses presented in this report (Table 1) are of 29 stream-One of the key principles of sedimentary geology is that the ability of a moving medium (air or water) to move sedimentary particles—and keep them moving—is dependent on the velocity of flow. The faster the medium flows, the larger the particles it can move.
