Hanzhong, Shaanxi Province was hit by heavy rain, and more than 21,000 people were evacuated. The heavy rain caused road interruptions in many places, and also affected water supply and electricity. The rain occurred during the National Day holiday, which had a great impact on the local tourism industry.

This year’s autumn floods have set historical records in many places. The affected areas are not only the city of Hanzhong in Shaanxi Province, but also many other cities. Although it is a heavy rain in autumn, the impact and losses it can bring are no less than those in summer.

The effects of heavy rain can be roughly divided into the following two types. 1. It has a major impact on traffic

Heavy rain has a great impact on road traffic safety and travel. Hanzhong is a hilly area, and many local roads are built on rocky hills. Long-term heavy rains can cause local mudslides and landslides. When these natural disasters occur on both sides of the road, they will cause damage and blockage to the road.

Roads being washed out and blocked are dangerous situations that often occur after heavy rains in mountainous areas. The interruption of roads has brought great inconvenience to local residents. Vehicles passing through this area will also be stranded due to road interruption. 2. Residents’ lives and buildings will be greatly affected

The arrival of heavy rains will cause local river water to surge, and the geological disasters caused by heavy rains will also affect local power equipment and water supply equipment. When electrical equipment is damaged, the power supply will be interrupted; similarly, when water supply equipment is damaged, water supply will also be interrupted.

Some buildings along mountains and rivers will also be in danger when affected by heavy rains. Debris flows on the mountain will impact houses, and surges in river water will wash away the foundations of houses, which may also cause house collapse.

Appropriate rainfall is good for everything, but excessive rainfall will cause disasters and increase the frequency of disasters. The above effects are more common in heavy rain weather. We need to make active and timely preparations for disaster prevention and reduction based on weather forecasts to minimize losses and dangers.
