Exhibit G — Water Information, Preliminary Adequacy Review <br />Page 2 <br />December 13, 2013 <br />summarizing what values were used and how they were obtained for the following <br />parameters: <br />a. Representative particle size, <br />b. Percent clay fraction, <br />c. Plasticity index, <br />d. Total unit weight, <br />e. Undrained shear strength, and <br />f. Critical shear stress. <br />Please also provide some discussion as to how these parameters are related to the erodibility <br />factor, Kd. <br />4. Windam B Model Input/Output Data, p. 44: Please explain why the Maximum Pool <br />Elevation for the Worse (Kd = 10) case is 0.96 feet lower than it is for the Best (Kd = 1) and <br />Strongest (Kd = ptl) cases. <br />5. Windam B Model Input/Output Data, p. 55: Similar to Comment 4, please explain why the <br />Maximum Pool Elevation varies between the four cases analyzed. <br />Drawy n <br />6. Drawing 1 of 1 Floodway and Erosion Mitigation Map: Please include: <br />a. a scale bar, <br />b. major contour elevation labels, and <br />c. contour intervals. <br />7. Drawing 1 of I Riprap Typical Section and Profile: Please provide: <br />a. a water surface elevation for which to reference the extent of the extended riprap <br />protection, <br />b. minimum depth of spillway and /or invert elevation(s) and crest elevation(s). <br />mAminVcl\minerals support\m- 2013 -064 coulsonlwatercomments _ meml2junl3.docx <br />
