What are the precautions for drifting?
2, cash, mobile phones, cameras and other valuables are best not to carry on the bus, easy to get wet; Friends with glasses, please find a rubber band to wear glasses. If you think the opportunity is rare, you must bring your camera. It's best to bring a stupid machine with low value, wrap it in plastic bags in advance, open it on a flat beach, wrap it when crossing a dangerous beach, and be ready to fall into the water at any time.
3. When crossing the dangerous beach, you should firmly grasp the safety rope, tighten your feet and lean toward the center of the hull; When going down the rapids, please keep the balance between the boat and the hull, hold the handrail on the inside of the hull, and the people behind you lean back slightly, so that the two can ensure the balance of the hull, parallel to the river and downstream.
In case of capsizing, don't panic at all, be calm, because you must wear a life jacket when drifting, and you can escape easily under normal circumstances.
Common sense of drifting
1. Tongue of Rapids: When the riverbed inclines downward, white waves appear on the calm water surface, and the rapids are usually deepest and fastest in the middle of the riverbed. In the noisy and shallow places on both sides of the river, the river is blocked and the flow velocity decreases, thus forming the phenomenon of faster water flow in the middle. Moreover, the faster the central water flows, the stronger it becomes, further washing away stones and sediment, removing resistance and obstacles, and forming a V-shaped tongue. The top of the "V" usually points to the channel with the least obstacles and resistance.
2. Rollback waves: reefs that are completely exposed to the water are easy to find, but some reefs hidden underwater are hidden. When the water flows over the top of the reef and into the diverticulum behind the reef (water stop). The river flows in the opposite direction (upstream). This phenomenon is called rolling wave, which appears downstream of semi-hidden and semi-exposed reef. If it is a large reef with a large hidden depth, there will be a large rolling wave downstream, which is usually called a "hole". This kind of "hole" is often so powerful that it can easily capsize. Some holes are like toilets. Once you enter it by mistake, it seems to be attracted by gravity, rotating like a gyroscope and stuck in it for a long time. So we should spare no effort to avoid it.
Preparation before drifting
Bring more clothes: Drifting will inevitably "get wet", and it is very uncomfortable to change without dry clothes after landing. Don't wear leather shoes when drifting. Flat slippers, plastic sandals and sports shoes are all ok. The weather is bad, the water is cold, and the weather is good. Pay attention to cold protection and sun protection. It is best not to use expensive clothes, shoes and hats for rafting.
Only drinking water is brought on the raft. Don't bring mobile phones, pagers, documents, cash and other things that are afraid of water.
Parents should pay attention: too young children should not drift or swim. The rivers in the mountains are complex and there are rapids and rapids everywhere. It is dangerous for children who are not sensible to walk around the ship.
