<br />Statement <br />Number <br /> <br />2096 <br /> <br />2725 <br /> <br />2620 <br /> <br />2750 <br /> <br />3073 <br /> <br />3075 <br /> <br />3235 <br /> <br />3265 <br /> <br />3280 <br /> <br />Notes and Remarks <br /> <br />WSEL NOT GIVEN, AVG OR MAX, MIN USED. The starting water <br />surface elevation wasn't given and therefore has been assumed <br />as halfway between the maximum and minimum elevation in the <br />cross section. <br /> <br />WSEL EXCEEDS LIMITS OF TABLE FOR MANNING I S "n". An assumed <br />water surface elevation fell outside the elevation limits <br />which specified Manning's "n" values on NV cards. Table <br />values were extrapolated for "n" value. <br /> <br />NO IMPROVEMENT MADE TO THIS SECTION. The subroutine CHIMP, <br />has been requested by the CI card and the excavation described <br />will not cut the existing cross section. <br /> <br />NUMBER OF COMPUTED POINTS EXCEED 100. The number of points <br />added by subroutine CHIMP have caused the total to exceed <br />100. Reduce the number of points on the GR card. <br /> <br />NEGATIVE SLOPE, WSEL - , EG - , PCWSE - , XEG - , WLEN - <br />RESTART COMPUTATIONS AT SECNO. , USING N-VALUES COMPUTED <br />FOR SECNP - A negative slope of the energy gradient has <br />been computed while trying to calculate roughness values that <br />will exactly duplicate the observed high water mark. Due <br />to this condition, the computations will start over again <br />using the previous section's roughness values. <br /> <br />SET S - SAVE. The computed slope at this section was negative <br />nr zero. The slope was set equal to the computed average slope <br />between this and the previous section. <br /> <br />SLOPE TOO STEEP, EXCEEDS X. The computed slope of the energy <br />grade line exceeded X, snd critical depth has probably been <br />crossed. If this cross section is a bridge, the special bridge <br />routine should be used in lieu of the normal bridge. <br /> <br />DIVIDED FLOW. The area below the computed water surface <br />elevation is divided into two or more segments by high <br />ground. If this condition occurs for three or more cross <br />sections consecutively, then separate profiles should be <br />run up each leg of the divided flow as the water surfaces <br />are not necessarily the same elevation across, the cross section. <br /> <br />CROSS SECTION EXTENDED X FEET. The cross sections ends have <br />been projected vertically 50 feet in order to calculate the <br />hydraulic properties of the cross section. Exactly X feet <br />of this extension were used. If this vertical sssumption <br />could produce unreasonable results, the input data should be <br />corrected. <br /> <br />Exhibit 7 <br />Page 3 of 8 <br />
