尼泊尔中部突发山洪：滑坡堰塞布迪甘达基河决口，5人失踪、49人获救
据路透社与美联社10月11日报道，尼泊尔中部当天凌晨突发山洪：戈尔卡（Gorkha）地区楚姆努布里（Chumnubri）村附近发生滑坡，滑体一度堵住布迪甘达基河（Budhi Gandaki River）形成堰塞，堰塞体随后决口，洪水挟带泥沙冲向下游沿岸村镇。戈尔卡位于首都加德满都以西约100公里。国际山地综合开发中心（ICIMOD）援引尼泊尔当局的初步说法称，洪水约在当地时间凌晨4点开始。
尼泊尔国家灾害风险减少与管理局表示，失踪的5人为2名女性、3名男性，均来自戈尔卡地区，目前暂无确认死亡的报告；另据尼泊尔军方通报，截至当天已有49人获救，其中包括1名外国人，军方还出动直升机把36名被困者空运转移，搜救仍在进行。
早期灾损报告数字不一：据路透社报道，约十多栋房屋与两座吊桥被洪水冲走，一处水电工程的营地受损、部分施工设备被卷走，一座连接戈尔卡与邻县达丁（Dhading）的公路桥也被冲垮；美联社经孟加拉联合通讯社援引武装警察部队发言人的说法称，戈尔卡和达丁两县共有65栋房屋被冲走，另有两座公路桥、两座吊桥被毁；还有媒体报道失踪人数可能达到10人。
戈尔卡地区最高行政官员米什拉（Dharmendra Kumar Mishra）表示，已要求下游沿岸村民撤离到安全地点。国家灾害管理局已向戈尔卡、塔纳胡（Tanahun）、奇特旺（Chitwan）及东西纳瓦尔帕拉西（Nawalparasi）等下游地区发出警戒。
这已是尼泊尔两个月内第二场重大洪灾：布迪甘达基河是特里苏里河的支流，今年8月其上游另一条支流因冰川崩塌引发灾难性洪水，造成1457人死亡、数千人失踪，边境城镇大量房屋与能源基础设施被毁。尼泊尔仍在恢复之中。
Flash Flood Hits Central Nepal After Landslide Dam Breach: 5 Missing, 49 Rescued as Homes and Bridges Swept Away
Flash flooding struck central Nepal early Sunday after a landslide temporarily dammed the Budhi Gandaki River and the natural dam then breached, Reuters and the Associated Press reported. A landslide near Chumnubri village in Gorkha district, about 100 km (62 miles) west of Kathmandu, blocked the river; the blockage then failed, sending water, mud and debris surging downstream. The International Centre for Integrated Mountain Development (ICIMOD), citing preliminary accounts from Nepal's authorities, said the flooding began around 4:00 a.m. Nepal time on Oct. 11.
Nepal's National Disaster Risk Reduction and Management Authority said five people — two women and three men, all reported from Gorkha district — were out of contact, with no confirmed deaths. The Nepal Army said 49 people, including a foreigner, had been rescued, and 36 stranded people were airlifted to safer locations, with search and rescue operations continuing.
Early damage reports varied. Reuters reported about a dozen houses and two suspension bridges swept away, a hydropower project camp damaged with construction equipment carried off, and a highway bridge linking Gorkha with the neighboring Dhading district washed out. The Associated Press, via Bangladesh's UNB, quoted Armed Police Force spokesperson Netra Bahadur Karki as saying 65 houses were swept away across Gorkha and Dhading districts, along with two motorable bridges and two suspension bridges; other outlets reported the number of missing could be as high as 10.
Dharmendra Kumar Mishra, Gorkha district's top official, said villagers living along the riverbanks downstream had been asked to evacuate to safe ground, and national disaster authorities issued alerts for the Gorkha, Tanahun, Chitwan, East Nawalparasi and West Nawalparasi districts.
The disaster comes two months after a catastrophic flood on another tributary in August, triggered by a glacier collapse, killed 1,457 people and left thousands missing; Nepal is still recovering from that event.
