4 Results from the Analyses XPSWMM models <br /> The results from the 4 different modelling variations described above yielded 2 different results for each <br /> lake. The static analyses for all variations are presented together with its dynamic counterpart since all <br /> other data, e.g. time to stabilize the water surface elevation, is non-applicable for the static analyses. For <br /> each lake and scenario, the six result parameters defined below have been extracted. <br /> i. Instantaneous Peak water surface elevation (static analysis): <br /> Maximum water surface elevation in lake after storm event when pumps are turned off (static <br /> analysis). <br /> ii. Static water surface elevation (static analysis <br /> Stable and equalized water surface elevation in the lakes after storm event when pumps are <br /> turned off(static analysis). <br /> iii. Peak water surface elevation (dynamic analysis): <br /> Maximum water surface elevation in lake after storm event when pumps are turned on as <br /> programmed as soon as the lake water surface elevation exceeds 5.3' (dynamic analysis). <br /> iv. Stable water surface elevation (dynamic analysis): <br /> The minimum water surface elevation reached after a storm event (dynamic analysis). <br /> V. Time to 7' (dynamic analysis): <br /> The required time in days after a storm event for the lake water surface elevation to recede to the <br /> top of wall at 7' (dynamic analysis). The duration of the storm is not included in the drawback <br /> times. <br /> vi. Time to stable (dynamic analysis): <br /> The required time in days after a storm event for the lake water surface elevation to recede to the <br /> stable water surface elevation (dynamic analysis). The duration of the storm is not included in the <br /> drawback times. <br /> The results, using the above result parameters, for both scenarios are shown in the Table 4-1. The results <br /> from Table 4-1 are shown graphically in Figure 4-1 and Figure 4-2. Figure 4-3 and Figure 4-4 shows the <br /> results for the dynamic analyses in graph form (water surface elevation vs. time)for all 26 lakes. The <br /> corresponding graphs for the static analysis can be found in Appendix F.
