When forming experimental channels, mimic what you see in the field. For example, meandering
gravel-bed rivers will have low point bars that slope gradually up to a floodplain, and relatively steep
banks on the outsides of bends. Routing brief flood pulses (high flows of about 190 ml/sec, see Figure
24, right side) through your channels will give them more realistic characteristics. Remember that your
modeled channels should be in a near-equilibrium condition in order to show the effects of
disturbances. The guidelines and videos at the following places will help you begin.

You may want to add sediment to the small pool that usually forms just downstream of the energy
dissipater. This prevents the upper ends of your channels from being sediment-starved.
