6. Calculation of the vertical distribution of concentration and suspended load.
7. LAB EXERCISES (flume with movable bed): measurement of the vertical velocity distribution,
application of the Shields diagram, size and velocity of sand ripples/dunes,
scour around bridge piers of various shapes and flow attack angles.
