Abstract

"This report was the result of an assigment [sic] to make a geologic reconnaissance of the headwaters of Coldwater River in northwest Mississippi, on which a site for a flood control dam had been made. At the time of the last field work in November, 1940, the boring program for borrow areas and for foundation had been completed.

The Sardis dam on the Little Tallahatchie River, some 35 miles southeast of site for the Arkabutla dam had been recently completed, it being the first of several designed for flood control purposes in the Yazoo basin, Mississippi. This was a hydraulic fill dam, having available nearby sufficient quantities of fine clay materials for relatively impervious core, naturally plastic; but with coarse material forming shell of dam for stability.

This type of construction, with impervious core and coarser shell would have been preferred at the Arkabutla site, but the ranges of soil types would not permit such choice, all material being nearly of same grain size.

At this time, I was working with the U. S. Engineer Office, Vicksburg, Mississippi, (Soil Section), under the direction of Mr. William H. Jervis, Engineer. It was at his suggestion that report was briefly summarized and details given in an appendix, due to the fact that he had found at times, engineers had not read or studied his reports on foundations, but would digest a summary. Hence the arrangement of the material.

Through official channels, this report reached the District Engineer, Vicksburg, District; the President of the Mississippi River Commission, (Brig. General Max C. Tyler and the Chief of the Engineers, Washington, D. C., and was in part responsible for the beginning of a geologic investigation of the Lower Mississippi Valley, July, 1, 1941"--Preface, page ii.
