• Gross Erosion, E (tons/acre/year) :Calculated from the above defined parameters for each area <br />defined. If the user selects an area from screen, E is calculated in each grid and the cumulative <br />value is calculated. <br />E = R * K * Ls * C * P ,where all the parameters are as defined above <br />Volume Calculations <br />Required User Input <br />Sediment Delivery Ratio (DR) :Default = 0.37 <br />Time Period,T (years) :Time of analysis; typically the time of the storm event <br />Density of the sediment (D) :The post-deposit density of the sediment <br />Runoff (I) :Calculated from some other routine like Curve Number and Runoff <br />Total Erosion (E, tons/year) =Sum of (E * Area) for all the areas. <br />Total Yield (Y, tons/year) = E * DR <br />Sediment volume per year (Vs) = Y /Density <br />Total Sediment Volume = Vs * Time period <br />• Runoff Volume =Runoff (I) * Total Area <br />Total Pond Volume =Runoff Volume + Total Sediment Volume <br />Pond 008 was constructed in the fall of 2000. Pond 009 was excavated in the spring of 2002. <br />Pond 014 was excavated in the spring of 2004. Ponds 010 through 013 have not yet been <br />constructed. Accordingly, the values for Ponds 008 and 009 are as-builts, and those values for <br />Ponds 010 through 013 are as-designed. The volume calculations for ponds 008, 009 and 014 are <br />shown in Attachment 2.05.3 (3) -4, and Attachment 2.05.3(3)-5 and Attachment 2.05.3(3) -5A. Map <br />Att 2.05.3-6-1 shows the detailed plan views and cross-sections for ponds 010 through 013. All <br />ponds will utilize a key cut into the dam and seep collars on the principal spillway pipe as shown on <br />the map. All dams will have a combined slope of 5.0:1.0 and will be compacted in no greater than <br />8" lifts to 90% of the tested maximum dry density of the material. <br />• (Revises ~/zoom 2.05.3(3) - 18 <br />
