2. Sediment Loading Analysis S <br /> The sediment and phosphorus mass flowrates were used to calculate the net annual loadings of <br /> the sediment and phosphorus. The calculations were done for TSS, VSS, TSS-VSS, phosphorus, <br /> and ortho phosphorus. Mass inflows were calculated at ERCR 15 and TBCR 35, and mass <br /> outflows were calculated at the Lake Orono dam. The calculations are shown in Appendix D. <br /> The calculation procedure is explained below: <br /> a. The average inflow rate (mass/day) for the time interval between two consecutive <br /> sampling events was calculated by adding the two inflow rates, and then dividing the sum <br /> by two. Similarly, the average outflow rate (mass/day) for the time interval between two <br /> consecutive sampling events was calculated by adding the two outflow rates, and dividing <br /> the sum by two. <br /> b. The mass inflow for the time interval was calculated by multiplying the average inflow 4110 <br /> rate (mass/day) by the time duration between the sampling events (days). The mass <br /> outflow for the time interval was calculated by multiplying the average outflow rate <br /> (mass/day) by the time duration between the sampling dates (days). <br /> c. The mass inflows for all the time intervals were added to get the annual mass inflow. The <br /> mass outflows for all the time intervals were added to get the annual mass outflow. <br /> d. The annual mass inflow and the annual outflow were divided by the number of days <br /> (365 days)to get the average mass inflow and outflow rates (tons/day) respectively. <br /> e. The inflow of bed load was calculated as a percent of the inflow of suspended load. No <br /> bed load was assumed for the outflow. <br /> f. The total inflow was calculated as the sum of the suspended load and the bed load. . <br /> N:\059E\0I RELKPJ V ERRPT-NCW 11 <br />
