The state of Bihar has significantly elevated its flood preparedness protocols following a severe flash flood in Nepal's Rasuwa district. Authorities in Bihar are now closely monitoring the Gandak and Kosi rivers, anticipating potential impacts from upstream water level changes.
Bihar Responds to Cross-Border Threat
Bihar's Chief Secretary recently conducted a comprehensive review of the situation with district magistrates. Officials in flood-prone regions have been instructed to maintain heightened vigilance and continuously monitor river water levels. This proactive stance is critical as developments in Nepal directly influence downstream areas within Bihar, given the interconnected river systems.
Nepal Flash Flood Devastates Rasuwa District
The alert in Bihar comes after a massive flash flood struck Nepal's Rasuwa district early Wednesday. The disaster tragically claimed the lives of eight people and left nine Armed Police Force personnel missing near the Nepal-China border, specifically in Timure. Numerous settlements, including Syaphrubesi, Betrawati, Mailung, Salletar, Shantibazar, Pairebesi, Khalti Basti, Sole, Trishuli, and Battar, suffered extensive damage. Market areas, particularly Syaphrubesi, were among the hardest hit, with photographs and videos revealing significant destruction to buildings and infrastructure. Critical police infrastructure, such as the Area Police Office in Timure and posts in Syaphrubesi and Rasuwagadhi, were also impacted.
River Systems and Downstream Impact
According to Nepal's Flood Forecasting Division, the torrent originated from the Tibetan side of the border, entering the Bhotekoshi river. By Wednesday afternoon, the floodwaters had reached Galchhi in Dhading and were expected to arrive in Muglin within hours. Authorities issued urgent warnings for residents along the Trishuli river to evacuate vulnerable areas and seek higher ground, cautioning that traffic along the Prithvi Highway and the Muglin-Narayanghat road could also be affected.
Meteorologists indicate that the flooding was not primarily caused by heavy rainfall directly in Rasuwa but rather by significant precipitation on the Tibetan side of the border. The Bhotekoshi river, originating in Tibet, flows through Nepal before converging with the Trishuli river system, which eventually connects to the Gandak. This hydrological link underscores why events upstream in Nepal are critically important for flood management in downstream areas of India, especially in Bihar.
Ongoing Rescue and Monitoring Efforts
In Nepal, extensive rescue operations are underway, with personnel from the Nepali Army, Armed Police Force, and Nepal Police mobilized. Additional forces are being deployed from other districts, and the National Disaster Risk Reduction and Management Authority has activated its network, coordinating relief efforts with medical teams, Scouts, and the Red Cross. Meanwhile, Bihar authorities remain focused on early detection of any rise in water levels in the Gandak and Kosi rivers, implementing preventive measures to safeguard potentially affected communities.
