Crossing a turbulent river without using floating equipment is a high-risk activity, and one needs to carefully evaluate one's own capabilities and environmental conditions. The following are the key steps and safety recommendations:
---
### **1. Assess risks (prioritize alternatives)**
-**Avoid taking risks**: If possible, look for bridges, shallows or gentle areas to detour. Turbulent water currents may hide the risk of whirlpools, rocks, or hypothermia.
-**Observe the water flow**: Choose a section of the river with relatively gentle water flow and narrow width, and avoid the outside of the curve (the fastest water flow) or areas with dense obstacles.
---
### **2. Preparation**
-**Wear appropriate clothing**: Light clothing (to avoid excessive water absorption), wear shoes to prevent scratches, and take off excess items (the backpack can be dragged, but it will increase resistance).
-**Teamwork**: When multiple people walk together, they hold hands in a straight line (perpendicular to the water flow), and the strongest takes the lead upstream.
-**Warm-up**: Cold water may cause cramps, move your limbs in advance to adapt to the water temperature.
---
### **3. River crossing skills**
-**Diagonally through the countercurrent**: Swim upstream at an angle of 45 degrees, using the thrust of the water flow to gradually come ashore (similar to the “Z”-shaped route).
-**Maintain a stable posture**:
-**Floating on your back**: Face up, spread your body flat, feet downstream (anti-collision), and move slowly down the river.
-**Breaststroke/side swimming**: Save physical strength and avoid facing the current head-on.
-**Avoid danger**:
-**Whirlpool**: Swim out parallel to the edge of the whirlpool, do not struggle directly.
-**Obstacles**: Buffer the impact with your feet to protect your head.
---
### **4. Emergency handling**
-**Cramps**: Float on your back and stretch your muscles, calling for help.
-**Washed away**: Stay calm and look for slow-flowing areas or shore to grab fixed objects.
---
### **5. Absolutely contraindicated**
-**Acting alone**: The risk is extremely high when there is no assistance.
-**Flood or turbid water flow**: The underwater situation is unknown, so resolutely avoid it.
-**Insufficient physical strength/can't swim**: Do not try.
---
###**Important principles**
**The power of natural waters far exceeds the limits of human physical fitness**. Even if the skills are proficient, turbulent rivers can still be fatal. Unless life and death are at stake, a safer solution should be chosen. If you must cross the river, it is recommended to bring a rope (fixed to the shore) or seek professional guidance.
