<br />Table 18. Description of the transects used to describe the <br />hydraulic and habitat conditions present at the Quarry <br />study site on the Green River (RM 307.5 - 308.6) <br /> <br />Transect Description <br /> <br />1 The thalweg is on river left. A deep, straight run. Substrate is <br />almost exclusively sand with one cell onr~ver left containing <br />rubble. A large sandbar observed in 1986"had disappeared in 1987 <br />as a result of shifting sands. The left bank is steep with dense <br />vegetation. The right bank is also vegetated but less steep. <br /> <br />2 The thalweg is on river left. A run with mostly sand/silt <br />substrate on river left and cobble on the extreme river right. A <br />large backwater on river left exists just below the transect. The <br />left bank is steep and vegetated. The right bank is sloping and <br />grassy. <br /> <br />3 A uniform run with sand/silt substrate on river left and <br />cobble/silt substrate on river right. The left bank is steep with <br />sparse vegetation. The right bank is terraced and sparsely <br />vegetated. <br /> <br />4 Represents a sand substrate with a cobble shoreline on river <br />right. A sandbar just below the water surface was apparent at a <br />flow of 5000 cfs; however, it did not appear at lower flows. Thus <br />causing a change in bottom profile. An irrigation pump located 30 <br />yards upstream had no apparent effect on flows at this transect. <br />The left bank is steep and sparsely vegetated; the right bank is <br />sloping with little vegetation. <br /> <br />5 A run with sand substrate and an extensive cobble bank on river <br />right. The thalweg is located on river right. A steep bank, <br />devoid of vegetation on river left continues up river to transect <br />7. The right bank is sloping with little vegetation. <br /> <br />6 A uniform troughlike channel with cobble/silt on river left. The <br />main channel is located on river right and exhibits a sand <br />substrate. The right bank is sloping and vegetated with tamarisk <br />and Russian olive. <br /> <br />7 A deep run dominated by sand substrate in the channel center, a <br />cobble/boulder substrate on river left and a cobble shoreline on <br />river right. The right bank is sloping and densely vegetated. <br /> <br />30 <br />
