1. A method of installing a fluid-fillable barrier into flowing water, the barrier comprising a tubular impermeable membrane having a longitudinal axis, first and second barrier ends at first and second ends of the longitudinal axis, a middle, fluid-fillable portion, a first attachment area on a first side of the longitudinal axis, and a second attachment area on a second side of the longitudinal axis, the second side opposing the first side;

  • a first tension member extending from the first attachment area to the second attachment area, a second tension member extending from the first attachment area to the second attachment area, the tension members each having at least one hole to equalize fluid pressure on either side of the tension member, wherein the first tension member has a taut length which is less than one-half of the taut perimeter of a cross-section of the tubular membrane, the taut length and the taut perimeter being measured at a common cross-section taken perpendicular to a longitudinal axis of the tubular membrane, and wherein the length of the second tension member, in a relaxed state, is at least one inch longer than the taut length of the first tension member, the barrier further comprising a first lifting loop at the first barrier end, and a second lifting loop at the second barrier end, each loop sized to receive a two-inch pipe, and each loop having a plurality of cut-outs, the method comprising the steps of;

    sliding a first pipe into the first lifting loop;

    connecting a second pipe to the first pipe through at least two of the cut-outs;

    connecting the second pipe to a first hoisting apparatus;

    sliding a third pipe into the second lifting loop;

    connecting a fourth pipe to the third pipe through at least two of the cut-outs;

    connecting the fourth pipe to a shoreline anchor point;

    using the hoisting apparatus to raise the first barrier end above the flowing water;

    inflating the barrier with fluid; and

    lowering the first barrier end into the flowing water.
