In the northern mountainous area of Qiangtai Qiangpi Hot Area, Yihua Water Conservancy Department: Matai'an River has prepared 6 million cubic meters of dredging capacity

Typhoon Qiangpi is expected to be closest to Taiwan on the 23rd and 24th, and rainfall will be concentrated in the northern mountainous areas and the Yihua area. The Water Resources Department held a video conference on flood prevention preparations today to take stock of the preparation status of each branch.

The strong typhoon Qiangpi is gradually approaching Taiwan. The current forecast path of the Meteorological Administration and various AI models is that the typhoon will gradually turn northward starting on the 22nd. The closest approach to Taiwan will be on the 23rd and 24th. Rainfall will be concentrated in the northern mountainous areas and Yihua area. The Water Conservancy Department of the Ministry of Economic Affairs emphasized today (21st) that the Water Conservancy Department took stock in advance and implemented strict arrangements, and pointed out that the Matai'an River embankment reconstruction project was completed ahead of schedule, and the downstream river channel has restored its flood discharge capacity to the century-old protection standard. An additional 6 million square meters of dredging opening contract capacity has been prepared.

Director of Water Conservancy Lin Yuanpeng held a video conference on flood control preparations to take stock of the preparations of each sub-department, and asked each river sub-department to contact the county and city government to speed up preparations, including inspections of river embankments, water gates, pumping stations and other water conservancy facilities, and to implement flood control cooperation with local governments.

The Water Resources Department stated that the dredging of Hualien Creek and Matai'an Creek has reached 23.85 million cubic meters. With the completion of the embankment reconstruction project ahead of schedule, the downstream river channel of Matai'an Creek has restored the flood discharge capacity of the century-old protection standard. An additional 6 million cubic meters of dredging opening contract capacity has been prepared and 6 pumps have been deployed in advance. High-standard embankment flood control projects continue to be carried out to strengthen flood control capabilities.

For the Wanli Creek barrier lake, the Water Resources Department pointed out that as of October 20, the water storage capacity was about 5.11 million tons. The current situation is stable and the overflow is stable. The Ninth River Branch assessed that the flood capacity of the Wanli Creek channel is greater than the designed flood flow (Q100). In addition, according to the extreme scenario of the Linbao Department Simulating the situation and local needs, emergency engineering has been completed to heighten and reinforce the embankment, and two pumps have been deployed on the right bank downstream of the Jianying Bridge. In addition, based on analysis by the Forestry Protection Office of the Ministry of Agriculture, the embankment heightening and reinforcement has been completed for the embankment section behind the embankment that has important preservation targets to prevent possible disasters.

The Department of Water Resources emphasized that special vigilance should be strengthened in areas with possible rainfall hot spots from typhoons and peripheral circulation, as well as disaster spots that have experienced flooding this year, including Shuangbei, Keelung, Taoyuan, Zhumiao, Yilan and other places. The current water level of Shimen Reservoir is about 243.12m, and the water storage rate is 92.23%. We will continue to refer to and analyze relevant information from the Meteorological Administration, estimate the reservoir inflow based on the latest predicted rainfall, and adjust the regulatory water release and flood control strategies hourly. The Tenth River Branch Office paid close attention to the changes in river water levels and notified the Taipei City Government (including the Jade Reservoir Management Bureau), the New Taipei City Government and other relevant units in advance. They coordinated disaster prevention at the "Greater Taipei Flood Control Platform" and strengthened control operations on evacuation doors and parking lots to alert the public as soon as possible.
