 53:173 Mechanics of
Sediment Transportation
This course covers basic laws governing sediment-particle fall velocity, applications to particle-size analysis; incipient motion; bed forms; bed load; suspended load; natural river processes; theory and practice of movable-bed model experiments. It covers classic theories in sediment-transport mechanics and river-bed instability. A variety of sediment-transport predictors as well as one-dimensional sediment-routing methods will be discussed. Toward the end of the semester, each student will be asked to review one journal paper closely related to the subject you have just learned and prepare a critical review report. You will be given an opportunity to present the finding in the class. After taking this course, you will be familiar with the peculiar characteristics of flow in alluvial streams, and to become able to apply the available techniques for predicting (1) bed-form regimes in alluvial streams; (2) depth-discharge relations for rivers; (3) sediment transport rates in rivers; (4) sediment-transport rates by wind; (5) sediment-transport rates by water waves; (6) design of stable channels in alluvium; and (7) reclamation and training of river channels.
