Pollutant transport in surface waters and in groundwaters

Animation (Chapter 3.5.2.)

The initial situation is that uniform flow conditions are prevailing in a 5000 m long channel:
· discharge is 4.83 m3/s per meter width
· flow is uniform and surface slope equals the bottom slope So=0.0015 and water depth is 1.73m
· Manning coefficient n is very small = 0.02
· sediment discharge is constant in the whole channel and elevation of the river bottom does not change

The only change is that sediment inflow from upstream is increased by 50 %. The result
of increase in sediment inflow is aggradation of the sediment starting from the upstream
end of the channel. [Kuva:sed_ani3.gif]
