Is there any range of cohesion values for coarse-grained soils?

I am working on cohesion and friction angle of different types of soils. The shear strength of coarse-grained soils are different from that of fine-grained soils.

I am curious to know how friction angle and cohesion parameters are chosen for a retaining wall design?

I understand the various soil tests and bore-hole drilling are done as a part of geotechnical investigation. But, I am not sure how the shear strength values are chosen for design of retaining...

I was wondering how two non-linear equations can be compared in terms of goodness of fit?

I am currently working with 2 non-linear equations; One is with 3 coefficients; The other is with 4 coefficients; I have used EXCEL SOLVER to minimise the sum of squared normalised residuals. I am...
