Dr. Sanders
By the end of
today's class, you should be able to do the following:
*
Describe the general methods/techniques for determining grain size
distribution of a sediment sample, and explain the use of the term
"percent finer".
*
Looking at a grain size distribution graph, differentiate between
sediment samples that are poorly graded and those that are well graded.
* Using a grain size distribution graph, read off the D10, D30,
and D60, and calculate the coefficient of uniformity and
the coefficient
of curvature.
* Construct grain size distribution curves for the sample analyses
distributed in class.
* Explain what is required in the "Lab Methods" presentation.
