<br />. <br /> <br />. <br /> <br />Table 1. <br /> <br />Four modifications made by Bruce M. Wahle to the original <br />IFG4 data decks developed by Keith Rose in 1983. <br /> <br />1) <br />2) <br /> <br />The stage of zero flow values were modified to reflect <br />lower hydraulic controls. <br />The substrate code was changed from a two-digit dominant- <br />subdominant scale to a one-digit modified Wentworth scale <br />based on the dominant particle size. <br />The water surface elevation values for the three flows <br />were averaged for the right and left banks and carried <br />out to the hundredths place. <br />A value of 4.06 feet was added to the bed elevations in <br />transects one and two. The reason for this addition is <br />unknown, but possibly it was done to aid in hydraulic <br />simulations. <br /> <br />3) <br /> <br />4) <br /> <br /> Staae At Zero Flow (SZFl Values <br />Transect Modified Original Transect Modified Original <br /> (BMWl (Rosel (BMWl (Rose) <br />lLa 83.9 79.79 lR 82.7 78.65 <br />2L 83.9 79.79 2R 83.8 79.69 <br /> (80.9)b (76.88) 3R 83.8 83.18 (83.18) <br />3L 86.45 86.45 4R 83.8 83.18 (82.71) <br />4L 86.45 86.45 (86.03) 5R 84.63 84.63 <br />5L 86.45 86.45 (84.37) <br /> <br />Transect <br /> <br />Modified <br /> <br />oriainal <br /> <br />6C <br />7 <br />8 <br /> <br />84.63 <br />84.63 <br />84.63 <br /> <br />80.6 (80.57) <br />79.4 (79.36) <br />83.2 (83.20) <br /> <br />a <br /> <br />River left represents 35 percent of the total river flow <br />River right represents 65 percent of the total river flow <br /> <br />b <br /> <br />Values within the parentheses represent the actual bed elevation <br />along the thalweg. <br /> <br />c <br /> <br />SZF was carried forward from Transect SR. <br /> <br />4 <br />
