<br />FLOOD FIGHTING METHODS 2003 <br /> <br />6.3A <br />Page 40 <br /> <br />Waterside Boil Inlet Detection <br /> <br />Water running through a levee and carrying material can <br />sometimes be stopped on the waterside, thus eliminating <br />the building of sack rings on the landside (see Figure 9). A <br />six foot long section of 2" diameter pipe secured to a S'x 6' <br />foot piece of plastic or canvas can be rolled over the inlet <br />hole on the waterside. Drive 1"x 3"x 2' stakes into the <br />shoulder of the levee. Suspend half filled sandbags on top <br />of rolled-out material with twine and tie off to stakes. <br />It can be difficult to locate the waterside inlet of boils. <br />Sometimes a swirl is observed at the water's edge. <br /> <br /> <br />Figure 9 <br /> <br />11 <br />
