13.3 Stream Erosion and Deposition – Physical Geology

In a stream, the most easily eroded particles are small sand grains between 0.2 mm and 0.5 mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow. The main reason for this is that small particles, and especially the tiny grains of clay, have a strong tendency to stick together, and so are ...

Filtration - MRWA

The rate of flow on a filter depends on the type of filter. A rapid sand filter will have a flow of 2-3 gpm/square foot of filter area. The high rate filter may have 4-6 gpm/square foot applied to the surface. A constant rate flow valve is almost fully closed when a filter is clean so that the desired water level on top of the filter is maintained.
