Soil's Rate of Subsidence

[cmichaelson]

If I'm digging a shallow trench for some minor construction, and then refill it with the excavated soil, how can I determine the rate at which that soil will settle?

The trench will only be a few feet deep and well above the water table. In addition, there will be no load placed on top of the fill, so I don't think the equations for 1 dimensional soil consolidation apply.

CMichaelson: If shallow (only a couple of feet) and no loads to be placed above it - why worry about the rate? Just make sure your "lumps" are broken down and give it some tamping . . .
