According to the Irrigation Works Management Department (General Department of Irrigation – Ministry of Agriculture and Rural Development), as of 4 p.m. on September 28, the Central and Central Highlands regions had about 212,577 hectares of unharvested rice, accounting for about 29% of the area. sowing summer-autumn crop, season 2022.
In which, in the North Central region, the unharvested area is about 47,500 ha / 320,000 ha planted, accounting for 14.8%. The unharvested area in the South Central region is 48,728ha/266,857ha planted, accounting for 18.3%. In the Central Highlands, the area of unharvested rice is 116,349ha/147,525ha, accounting for 78.9%.
Due to the impact of Typhoon Noru, the South Central region has about 431ha (90ha of rice, 341ha of vegetables) collapsed and flooded, including 79ha in Da Nang City, 262ha in Quang Ngai Province, 90ha in Binh Dinh Province (other localities are under construction). during statistics).
In the Central Highlands, there are about 962 hectares of affected crops (rice 270.5 hectares, other crops 692 hectares), including Kon Tum 262 hectares, Gia Lai 700.5 hectares (other localities are in the process of statistics).
Mr. Nguyen Manh Hung, Deputy Director of the Department of Irrigation Works Management, said that the General Department of Irrigation continues to urge localities to implement the contents of Official Dispatch No. 1518/CD-TCTL-QLCT dated September 25, 2022. on ensuring the safety of irrigation works, preventing the effects of typhoon No. 4 in the central provinces from Thanh Hoa to Binh Thuan and Gia Lai and Kon Tum.
Regarding the situation of irrigation reservoirs, as of the afternoon of September 28, in the South Central region, the average amount of water stored in reservoirs reached 39% – 93% of the design capacity. In which, Quang Nam province 55% (up 10% compared to September 27), Quang Ngai 48% (up 6%), Binh Dinh 39% (up 16%), Phu Yen 42%, Khanh Hoa 70%, Ninh Binh province. Thuan 65%, Binh Thuan 86%. Some reservoirs are storing high water such as: Suoi Trau (Khanh Hoa) 106%, Tan Giang (Ninh Thuan) 99%…
For some large reservoirs, there is still capacity to store floods. In which, Nuoc Trong lake has a water level of about 115.67/129.5m (normal water level rise), an increase of 2.13m compared to September 27. Incoming Q (amount of water to the lake) is 531m3/s while Q discharge is 42.3m3/s. The lake has 137 million m3 left for flood storage.
At Phu Ninh Lake, the current water level is 24.25/32m (normal water level rise), an increase of 2.1m compared to September 27. The lake has 202 million m3 left for flood storage.
The water level rise in Binh Dinh lake is 66.9/91.93m (normal water level rise), 4.68m lower compared to September 27, the lake is 203 million m3 for flood storage.
Previously, on September 25, the General Department of Irrigation sent an express message to the Departments of Agriculture and Rural Development in the North Central, South Central and Central Highlands provinces/cities; project management boards of provinces and cities are managing projects of repairing and upgrading irrigation works; Cua Dat and Ta Trach Irrigation Works One Member Co., Ltd. proposed to implement plans to ensure the safety of irrigation works and prevent the effects of typhoon No. 4 (Noru).
Accordingly, the units actively monitor weather information, rain and storm forecasts of specialized hydro-meteorological agencies, specialized agencies under the Ministry of Agriculture and Rural Development and direction from competent authorities. the right to implement the plan to ensure the safety and operate the irrigation works to ensure the service of production and people’s daily life when flooding or waterlogging occurs.
Units zoned crop areas at risk of flooding and inundation and prepared appropriate response solutions. At the same time, proactively operate irrigation works early to drain buffer water and drain water, ensuring to minimize damage when flooding or waterlogging occurs. At the same time, implementing the plan to ensure the safety of irrigation works, paying special attention to the safety of reservoirs under construction, critical reservoirs, reservoirs filled with water and having high water storage levels.
For reservoirs with flood discharge valve gates, adjust the lake water level to actively welcome floods, ensure absolute safety of the works and do not discharge abnormally, causing unsafety to downstream areas; at the same time, carry out reasonable water storage for reservoirs with low storage capacity. Strictly implement early warning for people in downstream areas before the reservoir discharges flood and when there is a risk of an incident.
With reservoirs with high storage levels, units need to closely monitor the incoming water flow to have a suitable operation plan; promptly handle abnormal situations according to the motto “4 on the spot” when there is a risk of construction incidents.
