Changes in soil mechanics terminology and soil testing procedures generated by revision of the Bureau's Earth Manual are reflected in this chapter. The previous table 8, "Average Properties of Soils," which is now table , was recompiled to include laboratory test results obtained since the last edition. In , Casagrande developed a mechanized apparatus with which to run the test which reduced the operator sensitivity of the test [1]*. The apparatus is still in use today and is the basis for the Bureau's liquid limit test (USBR Designation E-7) [2] (see fig. 1).
In the calculation of hydraulic conductivity*' (according to designation E of the U.S. Bureau of Reclamation Earth Manual, p. ) effective pres- sure was corrected for friction losses due to. DESCRIPTION The purpose of this third edition has been changed in scope and intent from that of the second edition. The Reclamation Manual consists of a series of Policy and Directives and Standards. Collectively, these releases assign program responsibility and establish and document Bureau of Reclamation-wide methods of doing business. All requirements in the Reclamation Manual are mandatory.
