## 根因

6英寸流动水可冲倒人；1英尺可冲走车辆；2英尺可移动多数汽车；驾驶员无法判断水下深度或路况，导致漂浮或冲入更深水道。

## 解决方案

1. ```
   Turn around, don't drown: find an alternate route or wait for water to recede. Use weather radar to check if flooding is expected: `curl -s 'https://api.weather.gov/points/39.7456,-97.0892' | python3 -c "import sys,json; d=json.load(sys.stdin); print('Flood watch:', d['properties']['forecastHourly'])"`
   ```
2. ```
   If stranded in rising water, exit vehicle immediately and move to higher ground; do not stay in car even if it seems safe
   ```
3. ```
   Use a personal flotation device (PFD) if crossing flood water on foot; never walk through moving water deeper than 6 inches
   ```

## 无效尝试

- **Check depth with a stick before driving** — Water may be deeper than stick length; current can sweep person away; road may be washed out underneath even if water is shallow (85% 失败率)
- **Drive slowly through water to avoid splashing** — Slow speed does not prevent hydroplaning or engine water ingestion; water can enter exhaust and stall engine, causing sudden stop and entrapment (90% 失败率)
- **Use a large SUV or truck to cross deeper water** — SUVs and trucks have higher ground clearance but are still vulnerable to floating at 1-2 feet; many flood deaths occur in large vehicles because drivers overestimate capability (80% 失败率)
