1. A fluid-fillable barrier comprising:

  • a. a tubular impermeable membrane having a longitudinal axis, opposite 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; and

    b. a tension member extending from the first attachment area to the second attachment area, the tension member having at least one hole to equalize fluid pressure on either side of the tension member,wherein, when the barrier is filled with fluid, and is in a place to block a fluid, the tension member prevents the barrier from being moved from the place by external fluid pressure, and wherein the 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.
