China's Guangxi deluged by flood-waters from upstream province, China News
BEIJING/HONG KONG — Towns and villages by a major river in China's Guangxi lay half-submerged as floodwaters from a province upstream roared into the mountainous region, with the expected landfall of a tropical cyclone later on Thursday compounding disaster risk.
The massive flooding that overwhelmed the cities of Rongjiang and Congjiang in Guizhou province on Tuesday has spread downstream to other parts of southwest China, including rural settlements in Guangxi by the banks of the Liu river, which originates from Guizhou.
The Guangxi township of Meilin was the worst-hit, state media reported on Thursday, with floodwaters at their peak more than four metres above what was considered safe.
Even as floodwaters passed and dangerous surface run-off began to recede, southwestern China — from Guizhou and Guangxi to Chongqing, Yunnan and Sichuan — remained on high alert for secondary disasters such as road collapses, landslides and hydro-dam overflows.
"Rural areas face significant challenges due to limited infrastructure and resources," said Chen Xiaoguang, professor at Southwestern University of Finance and Economics in Chengdu.
"Strengthening these systems in rural counties will be key to reducing the long-term impact of increasingly severe weather."
Urban areas typically have stronger capacity to respond to floods, he said, but not all cities are equally equipped. Rongjiang for instance is a county-level area where resources are more limited.
On Tuesday, the Guizhou city of Rongjiang, located at the confluence of three rivers, was hit by a flood on a scale that Chinese meteorologists said could only happen once in 50 years, and at a speed that shocked its 300,000 residents.
The flow rate of one section of the Liu river in Rongjiang surged to 11,800 cubic metres per second, the equivalent of nearly five Olympic-sized swimming pools. That was more than 80 times the average rate of flow. At least six people were killed.
As deluge-hit areas began to remove silt left behind by the flooding and restore power, telecommunications and water networks, rains from a tropical depression expected to make landfall in Guangxi on Thursday night could affect restoration and cleanup work or even risk a new round of flooding.
The tropical depression made landfall on China's island province of Hainan early on Thursday, and later again in Guangdong on the mainland, bringing more rain to a region still reeling from Typhoon Wutip two weeks ago.
Extreme storms and severe flooding, which meteorologists link to climate change, increasingly pose major challenges for Chinese officials, as they threaten to overwhelm ageing flood defences, displace millions of people and cause billions of dollars in economic losses.

Heavy rain hits China's flood-stricken Guizhou for second time in a week
SHANGHAI - Heavy rain struck China's southwestern Guizhou province again on Saturday, half-submerging the already flood-stricken riverside city of Rongjiang for a second time this week and prompting the evacuation of residents to higher ground. Located at the confluence of three rivers and home to 300,000 residents, Rongjiang was inundated earlier this week by record downpours that left six dead and forced more than 80,000 people to flee their homes. The amount of rain that fell over 72 hours was double the city's average for June. In response to the new round of flooding, authorities raised the city's flood emergency response level to the highest level on Saturday. The benchmark hydrological station on one of the rivers estimated that the peak water level would hit 253.50 metres (832 ft) at around 5 p.m. (0900 GMT), exceeding the safety threshold by 2 metres, state broadcaster CCTV said. Earlier this week, the peak water level reached 256.7 metres, the highest since 1954, the Guizhou provincial government said in a statement to Reuters on Friday, blaming "the extreme climate" for the flooding. The floods in southwest China are set to hit local economies. Rongjiang was removed from the national poverty list in 2020. It then saw an unexpected tourism boom after a local soccer league nicknamed "Village Super League" became a social media sensation, attracting thousands of fans and tourists. On Tuesday, the soccer pitch was up to seven metres under water. China has battled with summer floods for millennia, but some scientists say climate change is resulting in heavier and more frequent rain. Massive flooding could set off unforeseen "black swan" events with dire consequences, such as dam collapses, Chinese officials say. In southern China over the past two days, 13 major rivers in Yunnan, Guizhou, Guangxi and Hainan were hit by storms and had risen above their warning levels, CCTV reported, citing the Ministry of Water Resources on Saturday.

Underground tank to prevent flooding in low-lying Jalan Besar area completed
Located next to Rochor Canal, the Syed Alwi Pumping Station is designed to divert storm water from the upstream of Rochor Canal into an underground tank. ST PHOTO: BRIAN TEO SINGAPORE – The low-lying Jalan Besar area and parts of Little India are now better protected against floods with the completion of a new pumping station with an underground tank along Syed Alwi Road. Located next to Rochor Canal, the Syed Alwi Pumping Station is designed to divert storm water from the upstream of Rochor Canal into an underground tank. The water is then pumped out of the tank – which is able to hold about 9,300 cubic m of water, or about the total capacity of four Olympic-size pools – into a downstream section of Rochor Canal during and after storms. This ensures that storm drains, which collect rainwater run-off from the Jalan Besar area, are not overwhelmed during intense rain when the water level in the canal is high. The completion of the underground tank was announced by Minister for Sustainability and the Environment Grace Fu in a recorded address at the 2025 Singapore International Water Week Spotlight conference on June 23. 'As ground raising is not possible in (Jalan Besar), the dual-purpose storage and pumping station was conceptualised as an alternative solution to enhance flood resilience,' she said in the video, which was aired at the event held at the Singapore Expo. National water agency PUB, which built the $33 million pumping station, said it 'forms part of PUB's diverse storm water management infrastructure to strengthen Singapore's flood resilience as climate change brings about more frequent and intense rainfall'. The fully automated pumping station, which was completed in June, also has floodgates at the Syed Alwi Road drains that shut to prevent backflow of water from Rochor Canal into the Jalan Besar area. Construction of the Syed Alwi Pumping Station began in 2021, with most of the costs covered by Singapore's Coastal and Flood Protection Fund. The fund, which was set up with an initial injection of $5 billion in 2020, received an additional injection of $5 billion from Budget 2025, to fund both coastal protection and drainage infrastructure. Jalan Besar is a low-lying area that experienced flooding from the 2000s to 2010s. The last time it experienced a flooding incident was on Nov 13, 2014, said PUB. Among the efforts made to combat flooding in the area were the upgrading of drains along Syed Alwi Road and raising road levels in 2014. Rochor Canal, which runs along Sungei Road and Rochor Canal Road towards Marina Reservoir, was also widened and deepened in 2015 to increase its drainage capacity. These measures enhanced flood protection in nearby areas such as Veerasamy Road, Hindoo Road and Desker Road. However, expanding drainage infrastructure and raising ground levels are not feasible for all sites, said Ms Gayathri Kalyanaraman, senior principal engineer for drainage planning at PUB's catchment and waterways department. 'The low-lying Jalan Besar area illustrates this challenge,' she said. It is not possible to raise roads and buildings in the area, which has many heritage buildings such as Masjid Angullia and the shophouse at 75 Maude Road. This is where the new pumping station comes in – enhancing the area's flood resilience. Storm water will accumulate in the underground tank, which is 11m high and has the capacity of four Olympic-sized pools and can hold about 9,300 cu m of water. ST PHOTO: BRIAN TEO When the water level in the tank reaches 4.5m, the pumps will be automatically activated to discharge water into Rochor Canal via two outlets. When the water level is below 4m, the water will be discharged by two other smaller pumps into the canal. ST PHOTO: BRIAN TEO Two other pumping stations, built in the 1990s, enhance flood resilience in the low-lying Tanjong Katong estate. Despite its efforts to enhance Singapore's drainage infrastructure, 'absolute protection is not possible, and building community resilience is key', said PUB. Stakeholders such as building owners and contractors can ensure proper maintenance of internal drainage systems, and implement flood protection measures according to stipulated guidelines to better protect their properties, it added. Meanwhile, the Syed Alwi Pumping Station has brought more verdancy to the Rochor area, with features like a green roof and green wall. Coming up next to it is an open plaza that will provide a recreational space integrated with nearby Build-To-Order development King George's Heights, which is under construction. As part of efforts to protect Singapore's coasts from sea-level rise, the Republic has divided its coastline into eight stretches, and is conducting separate studies on them to determine the most suitable ways to protect each stretch from future rising seas. Where possible, these solutions will be multifunctional, enhancing the environment and supporting better land use, said Ms Fu. She added that PUB will soon launch a risk assessment study to evaluate eight offshore islands' vulnerability to sea-level rise. This is an expansion of the work being done on the mainland, and more details will be revealed in a few days.

Flood-hit China expands social security net as extreme rain takes toll
[BEIJING] China has expanded the economic safeguards for segments of its population affected by flood control schemes in times of extreme rainfall, including pledges of direct compensation from the central government and payments for livestock losses. In China, diverting flood-waters to areas next to rivers is a major step in managing downstream flooding. As extreme rainfall grows in frequency, China is increasingly utilising such areas, some of which have been unused until now and have been populated by farms, croplands and even residential buildings, stoking social tensions. According to revised rules on compensation related to flood diversions released late on Friday (Jun 27), the central government will now bear 70 per cent of all compensation funds, with local governments responsible for the rest. Previously, the ratio was to be decided based on actual economic losses and the fiscal situation of local governments. Livestock and poultry that cannot be relocated in time before the arrival of diverted flood-waters will also be included in the compensation scheme for the first time. Previously, only the loss of working animals could be claimed for compensation. In the summer of 2023, almost one million people in Hebei, a province on the doorstep of Beijing, were relocated after record rain forced authorities to divert water from swollen rivers to some populated areas for storage, triggering anger over the homes and farms sacrificed to save the Chinese capital. China currently has 98 designated flood diversion areas spanning major river basins including the Yangtze River basin, home to a third of the country's population. During the 2023 Hebei floods, eight flood storage areas were used. A NEWSLETTER FOR YOU Friday, 2 pm Lifestyle Our picks of the latest dining, travel and leisure options to treat yourself. Sign Up Sign Up Since the start of the East Asia monsoon in early June, precipitation in the middle and lower reaches of the Yangtze has been up to two times higher than usual, officials from the China Meterological Administration told reporters on Friday. In other parts of China, daily rainfall measured by 30 meteorological stations in provinces such as Hubei and Guizhou broke records for the month of June, they said. Guizhou was the focal point of China's flood alleviation efforts this week, with one of its cities hit by flooding on a scale that meteorologists said could only happen once in 50 years, and at a speed that shocked its 300,000 residents. That prompted Beijing to issue pledges on Thursday to move vulnerable populations and industries to low-flood areas and allocate more space for flood diversion. REUTERS
