Belarus Flooding: Is It A Common Occurrence?

Belarus has experienced flooding in the past, with the spring flood being the most critical phase of the river water regime in the country. The water levels in large rivers rise between 8.6 and 12.8 meters above the normal level, while middle-sized and small rivers see a rise of approximately half of that. The country has also experienced damaging floods, with the heaviest ones occurring in 1956, 1958, 1974, 1979, 1993, and 1999. The most recent instance of flooding in Belarus was in July 2024, when heavy rains brought the capital city of Minsk to a standstill, disrupting public transport and causing traffic congestion. The floods also resulted in power outages in over 2,000 towns and villages across the country.

Belarus' capital, Minsk, has experienced flooding that disrupted public transport

Minsk's public transportation system consists of buses, trolleys, trams, and private route taxis or "marshrutkas." The city also has an urban train connecting the Minsk Pasažyrski station with Ždanovičy and the Minsk Sea. During the flooding in July 2024, residents of Minsk faced challenges getting around the city due to the disrupted transport routes.

To manage the situation, rescue teams were deployed to pump out water from the affected areas. The Emergencies Ministry coordinated the response, and updates were provided by local media outlets. This incident highlights the impact of extreme weather events on urban infrastructure and the importance of preparedness and resilience in mitigating the effects of flooding.

To reduce the risk of flooding and its impact on public transport in Minsk, several adaptation strategies can be considered. These strategies may include improving flood management plans, restoring wetlands and degraded forest land, implementing sustainable drainage systems, and adopting a long-term perspective in project planning and design to account for the potential impacts of climate change.

Flooding in Belarus is classified as a high urban flood hazard

Belarus has experienced several damaging floods in the past, with the spring flood being the most critical phase of the river water regime in the country. The water levels in large rivers rise between 8.6 and 12.8 meters above the normal level, while middle-sized and small rivers experience a water rise of approximately half of that. The flood period typically lasts between 30 and 120 days, with the shortest floods occurring in the Neman catchment area and the longest in the Pripyat catchment basin.

The most recent significant flood in Belarus occurred in July 2024, causing extensive damage, power outages, and fatalities. The capital city of Minsk was particularly affected, with disrupted transportation links and flooded buildings. This event underscores the classification of Belarus as an area with a high urban flood hazard.

The high urban flood hazard classification for Belarus indicates that life-threatening floods are expected to occur at least once in the next ten years. This classification is based on modeled flood information and highlights the need for project planning, design, and construction methods to take this hazard into account. The increasing frequency and intensity of precipitation days in winter, as well as the rise in extreme rainfall events, further contribute to the high flood hazard level.

To mitigate the risks associated with flooding in Belarus, it is recommended to obtain pre-existing flood hazard information, consult local flood zoning data, and engage with technical experts who can provide a detailed understanding of the flood risk posed to specific projects or developments. Additionally, implementing flood management measures, such as catchment management and flood defenses, is crucial.

Belarus has experienced damaging floods 10-12 times in the last 50-70 years

Spring floods are the most critical phase of the river water regime in Belarus. In large rivers, the water level rises 8.6–12.8 m above the normal level, while in middle-sized and small rivers, it rises approximately half as high. The flood period typically lasts between 30 and 120 days, with the shortest floods occurring in the Neman catchment area and the longest in the Pripyat catchment basin.

The frequency of large flood events is expected to increase due to the intensification of anthropogenic pressures within the catchment area, leading to considerable changes in runoff conditions. This includes factors such as land-use change, river channel modifications, and increased activities in flood-prone areas.

To mitigate the impact of flooding, Belarus can implement improved flood management plans, restore wetlands and degraded forest land, and enhance efficiency in the water sector through pricing mechanisms and infrastructure adjustments. Non-structural measures, such as source control, laws and regulations, economic instruments, and flood forecast-warning systems, are also crucial for sustainable flood risk reduction.

Belarus' southern regions were hit by a severe storm in July 2024, causing flooding and power outages

Belarus' southern regions were battered by a severe storm in mid-July 2024, causing flooding and power outages. The storm, which began on July 14, destroyed major power lines, uprooted trees, and tore off roofs, leaving over 2,000 towns and villages without electricity. The worst-hit city, Mazyr, home to a major oil refinery, was still reeling from power outages in some areas. The storm also resulted in fatalities, with six people, including two children, losing their lives.

The capital city of Minsk experienced significant disruption due to the severe weather. Heavy rains turned the streets into rushing streams, flooding buildings and trapping drivers in their cars. Public transportation was severely impacted, with passengers stranded in trams and buses. The Emergencies Ministry reported that 38 street segments, one parking site, one building, and two underpasses were affected by the floods, leading to the temporary shutdown of two subway stations.

The storm primarily affected the Brest, Gomel, and Mogilev regions in southern Belarus. The Deputy Prime Minister, Anatoly Sivak, noted that the energy system lost all power generating and supplying lines in the Mazyr region and surrounding areas due to the abnormally strong winds.

The consequences of the storm extended beyond the initial damage and power outages. The Belarusian politician Franak Viačorka reported on social media that around 300 towns and villages continued to experience power disruptions even after the storm had passed. Additionally, the severe weather conditions disrupted daily life in Minsk, with people blocked in public transport and some buildings damaged.

To manage the impact of such flooding events, Belarus can implement adaptation strategies. These include improving flood management plans, restoring wetlands and degraded forest land, and increasing the efficiency of the water sector through pricing mechanisms and infrastructure specifications. By enhancing their resilience to flooding, Belarus can reduce the likelihood and magnitude of future flood events.

Belarus' future river flood risk is expected to increase due to intensifying anthropogenic pressures within catchment areas

Belarus has experienced damaging floods between 10 and 12 times in the last 50 to 70 years, with the heaviest flooding occurring in 1956, 1958, 1974, 1979, 1993, and 1999. The country's future river flood risk is expected to increase due to intensifying anthropogenic pressures within catchment areas.

Belarus' Flood History

Spring floods are the most critical phase of the river water regime in Belarus. During this period, water levels in large rivers can rise by 8.6 to 12.8 meters above the normal level, while middle-sized and small rivers experience a rise of approximately half of that. The flood period typically lasts between 30 and 120 days, with the shortest floods occurring in the Neman catchment area and the longest in the Pripyat catchment basin.

The most recent major flood in Belarus took place in 1999, when the floodplain of the Goryn and Ubort Rivers in the Polesie Area was 1.0 to 3.3 meters under water, causing significant economic damage.

Intensifying Anthropogenic Pressures

Several factors contribute to the intensifying anthropogenic pressures within catchment areas in Belarus:

• The economic value of flood lands is constantly increasing due to irrigation, higher crop yields, expanding settlements, and improved transport communications.
• Land-use changes, deforestation, urbanization, and wetland reduction impact rainfall-runoff relations, leading to increased flood risk.
• The construction of impermeable surfaces, such as concrete, in high-density areas forces water to flow over the land, increasing the likelihood of surface water flooding.
• Obstruction of waterways, such as poorly located bridges, can restrict water flow and increase the potential for flooding.
• Climate change influences precipitation patterns, with more frequent and intense precipitation days in winter and an increase in extreme rainfall events.

Strategies for Adaptation

To mitigate the impacts of future flooding, Belarus can implement the following strategies:

• Improve flood management plans: This includes restoring wetlands and degraded forest land, as well as enhancing the efficiency of the water sector through pricing mechanisms and adapting water infrastructure.
• Adopt non-structural measures: These are more sustainable and reversible, including source control, laws and regulations, economic instruments, flood forecast-warning systems, and awareness-raising initiatives.
• Implement structural measures: In certain cases, structural measures such as flood defenses and resilient design may be necessary to protect critical infrastructure and reduce flood risk.
• Relocate vulnerable projects: For projects exposed to high flood hazard, consider relocating to areas with lower flood risk, taking into account other hazards and factors such as escape routes.
• Early warning systems: Utilize early warning systems to provide communities with advanced notice of flood events and trigger mitigation protocols.
• Integrated Flood Management: Instead of traditional flood control methods, adopt an approach that manages the water cycle as a whole, maximizing the benefits of floodplains while reducing flood risk.
