    Velocity Reversal in Pool-riffle Sequences

    There is an exponential decline of bed material particle size as you move downstream due to the fining as a result of abrasion and sorting. Smaller particles are preferentially entrained and transported creating a set of bedforms. The most common are pool-riffle sequences which are characteristic of many single-channel alluvial riversĀ (Carling & Orr, 2000). They […]
