Abstract:
At least two mesh bars (35) adapted for inclusion in a mesh cell (30) of netting (51), the mesh bars (35) comprising a continuous length of material having:a lay with a common direction throughout the length thereof; a cross-sectional shape selected from a group consisting of quasi-triangular (36a-36c and 60a-60c), L-shaped, Z-shaped, parallelogram and quasi-parallelogram; and a longitudinal axis of symmetry (38); the two mesh bars (35) when included in the mesh cell (30) meeting at a coupler (34) at which the longitudinal axis of symmetry (38) of the continuous length of material turns,during field operations in which the netting (51) moves through a water entrained environment:water flows past the mesh bars (35) respectively in two different directions with respect to the common lay thereof; the directions in which water flows past the mesh bars (35) is neither parallel nor perpendicular to the longitudinal axis of symmetry (38) of the mesh bars (35); and as water flows past the mesh bars (35), the cross-sectional shapes of the mesh bars (35) produce a net component of force that is oriented in a direction perpendicular to a combined drag component of force for the mesh bars (35).
