On uneven ground, use shims made from ¾-inch plywood or 2-by-4 scraps under the support
feet as necessary.
Be sure all four feet of each support are properly supported. One horse is modified to provide
clearance for the reservoir (see Figure 9). Place the supports so this opening lies at the
downstream end.
The Emriver supports have a difference in height of about 3 in (76 mm), yielding a box
slope of 6%.
The slope of channels in the box will be determined by the position of the standpipe, so
the exact box slope is not necessarily important.
Note:
Labels on the supports display arrows that indicate proper placement and orientation,
with the shorter support at the geomodel’s downstream end. See Figure 4
.
