Just upstream of <br />the ditch, there is a trailer court in the far left overbank. The <br />"n" values for both banks, channel, and right overbank were estimated <br />as 0.1, .04 and .04, respectively. <br />The left overbank will vary. In the trailer court, an "n" <br />value of .08 was chosen; elsewhere an "n" value of .045 was selected <br />for the pasture lands upstream of the ditch, while .06 was assumed <br />throughout the commercial areas just downstream of U.S. Highway 287. <br />Refer to Pictures 28 and 29. <br /> <br /> <br />.1 <br />/'~ l <br />,. ., <br />,1'11 <br />" <br /> <br />1; <br /> <br />'.> <br /> <br />\, \ <br />" <br /> <br />picture 28 - Looking upstream at the channel <br />above t~e ~arimer and Weld County <br />Canal. ~=.~4 in the channel, 0.1 <br />on the banKs, and .045 in the over- <br />banks. <br /> <br />-26- <br />
