Affected by
the recent heavy rainfall across the country, the water levels of 433
rivers in China have surpassed danger level since early June, 33 of
which hit historical highs, said the Ministry of Water Resources on
Monday. From early
warning systems to rescue missions, various forms of sophisticated
technology have been used to save lives and property in the fight
against floods. China's BDS warns of geological disasters The recently
completed BeiDou Navigation Satellite System (BDS) has played an
integral role as an early warning system for geological disasters caused
by floods. Several rounds
of heavy rainfall have hit Shimen County in south China's Hunan
Province since the start of this year's flood season. A massive
landslide occurred there on July 6, after heavy rains caused 3 million
cubic meters of a mountainside to collapse. The area was evacuated
before the incident occurred, and no one was injured. On June 24,
Shimen County officials were notified of a potential geological disaster
based on BDS' findings. The satellite detected anomalies in the
monitoring data of hidden geological hazard points, CCTV reported. The local
authorities immediately relocated residents in nearby villages. Right
before the landslide on July 6, another batch of villagers near
suspected danger zones was evacuated. Wang Dunlei,
who is in charge of flood and drought prevention in Changde City, told
CCTV that with high-tech means like BDS, the city can identify danger
zones in advance and avoid casualty. Fighting floods smartly In Anqing City
in east China's Anhui Province, a local telecom operator uses 5G
technology and virtual reality (VR) to observe water levels in
real-time. With the
low-latency 5G signal, monitoring personnel can quickly receive footage
shot by 360-degree cameras and observe even subtle changes in water
levels through VR goggles, thus increasing the efficiency of inspection
during the flood season. The intense rainfall has caused severe flooding and waterlogged the soil in many cities in the country. In cities such
as Fuzhou in southwest China's Fujian Province and Guiyang in southwest
China's Guizhou Province, areas that easily accumulate water are marked
on a map so that when it rains heavily, monitoring personnel can check
the real-time status of each catchment area without the need to go out
into the field. High-tech
hardware like drones and rescue robots have also made significant
contributions to saving lives during the flood season.
