Methods to Determine Vertical Stress

The load applied to the soil is transferred to the underground. The presence of water at soil pores and solid grains above the soil are the primary components that are responsible for the effective load transfer. Due to the load acting, the internal component of the soil or the underground formations undergoes deformations or a tectonic shift. The amount of deformation depends upon the amount of load acting on the soil surface, which indeed, depends on the weight of everything present above the soil. Due to this, the underground soil element develops internal stresses which try to resist the tectonic changes.

3. At a different location in the Chesapeake, the same u-=4.4 cm/s and z,=3.1 cm were measured. At this new location, at 1 m above the bed, the Reynolds stress was measured to be u w' =-17.8 cm²/s² and the flux Richardson number was 0.23. First compute the velocity gradient at 1 meter above the bed using the logarithmic distribution and then determine the buoyancy flux ( w'p') at this location. Is the water column stably stratified?
