Municipal workers have commenced emergency repairs on the retention wall along the Dhobikhola River in Buddhanagar, Kathmandu, following the subsidence of a bridge due to severe erosion. The incident, which occurred on Thursday, has been attributed to persistent flooding and increased riverbank erosion exacerbated by the narrowing of the river caused by encroachment and the construction of adjacent roads.
The affected bridge, a crucial crossing for residents, showed signs of structural weakness earlier in the week, prompting immediate action from city authorities. The rapid deterioration was caused by the continuous heavy rainfall, which has swollen the Dhobikhola River, putting significant pressure on the riverbanks and adjacent infrastructure.
Local officials reported that the encroachment along the riverbanks, including unauthorized construction and narrowing due to road expansion projects, has significantly reduced the river’s capacity to handle floodwaters. This situation has not only accelerated the rate of erosion but also heightened the risk of further infrastructural damage in the area.
Municipal engineers and construction crews have been deployed to reinforce the retention wall and stabilize the surrounding soil. The repair work includes placing large boulders and concrete reinforcements to prevent further erosion and protect the integrity of the bridge. According to the Kathmandu Metropolitan City Office, these measures are expected to be completed within the next few days, weather permitting.
The incident has sparked renewed discussions about urban planning and environmental management in Kathmandu. Experts have long warned that unchecked urbanization and inadequate river management practices could lead to increased flood risks and infrastructure failures. The situation along the Dhobikhola River highlights the urgent need for comprehensive river management strategies that prioritize sustainable urban development and the protection of critical water bodies.
Additionally, the recent events have prompted the authorities to expedite plans for a broader river restoration project aimed at enhancing flood resilience. This initiative includes measures such as the removal of illegal encroachments, the creation of buffer zones, and the implementation of sustainable drainage systems to manage runoff and reduce erosion.
Local authorities have urged residents to exercise caution when travelling near the affected area and to adhere to any traffic diversions or safety advisories issued during the repair process. The city’s public works department is also conducting assessments of other vulnerable infrastructure in the region to prevent similar incidents in the future.
