Gabions curve concave shore should follow along under the pick, memorial principles laid down close to 9 turn should flow potential.
Gabions first position and length should be carefully selected. Under normal circumstances the first thin gabion should be arranged on the upstream side of the turning point of the water, so the water does not close before the banks will be able to control the mainstream consumer brake flow potential, played the role make the best use of. If the first dam items arranged in the top red dot red dot or less, gabion can not play a good role.
In the top of the red dot, the water approaching, the impact force, unable to meet the flow outward care, defense difficult. City set at entry points below the red, the danger has become, gabion no much effect. First gabion not too long. If the first gabion laid too long projections, will form itself excessive force seriously disrupted the water flow to the dam after all defense caused difficulties. Experience tells us that curved over the top to protect 40% of the entire length to protect the length of the curved top 60% of the length of the following protection.
