Grain Size Application This is one application which might become handy if you have collected plenty of granulometric samples and have them analyzed in a lab. Coupled with another application, MISCELLANEOUS, in which you may calculate hydraulic conductivities based on empirical formulas by Hazen, Kozeny, Terzaghi, Slichter, Zamarin, and the U.S. Bureau of Reclamation, you can produce hydraulic conductivities and transmissivities for layers in boreholes.

You may produce grain size curves as a documentation report, or you may keep them in the data base.
