Although the main area of Khanh Hoa has serious problems, many of the areas are flooding in water, water shortages and saltwater in the face of unusual challenges. in the region. last year.
The Ministry of Natural Resources and Environment has just been issued to the People of Thua Thien-Hue, Quang Nam, Quang Ngai, Binh Dinh, Gia Lai, Phu Yen and Da Nang's Committees to ensure that water supply is low ground in season. thin in 2019.
Water levels in the flood season
At present, the Huong, Vu Gia – Thu Bon, Tra Khuc, Kon-Ha Thanh and River Basin were in the season of flood. However, from the beginning of the flood season up to now, there are no floods in the basins. Most of the large reservoirs have very low water levels. Even some lochs are dying.
Based on starting data, the amount of water collected in the deposits is very low (only 20 – 45%), compared to the lowest water requirement at the beginning of the dry season just 35 – 50%. According to hydrographic movement in the last few months of the year, water in the middle and central Highlands tends to be 20-50% lower than average for many years. So, if the risk of water shortages in the flood from time to time floods is very large, it is still difficult by the end of 2018 and early in 2019 it's also very difficult. stress.
Other hydroelectricity on the River Vu Gia as A Vuong is also a poor water resource. Mr Ngo Xuan, General Director of the V Aong Power Co-Operating Stock Company, from 1977 to date, has the lowest level of water to the lake.
This is a Song Tranh in another major powerful energy project on the River Bon River, which is also a " get low scheduled water. Mr Vu Van Lan, Deputy Director of the Song Tranh Hydro-Electric Company, said: "There is a water stream in the lake 10/1818 70 m3 / second, which equates to 27% for many years. November, as long as the flooding center is, the stitch's climb is even higher, with 43.5 m 3 / s, only equivalent to 10% for many years. After 45 year, the country's record last year, "he laments.
Frequency common in many areas
Until now, Thua Thien-Hue's division has had a number of floods compared to its annual tour, but many of the older people still have a great deal. waiting "long neck". As well as floods, which cause damage to human resources, there are many values in the remaining floods, especially in agricultural production. "This year, floods almost caused not only sedimentary moisture, but also mice and mermaids. In addition, this situation and season are also a reservoir of water Fortunately, especially for agriculture, "said Nguyen Cuong (45 years), a landowner in the Quang Loi area, the area of Quang Dien, worried.
The concern about flooding caused by hydropower reservoirs and there is a risk of bringing up waterfall in Thua Thien-Hue. The department's mechanical division from the beginning of the gland season up to now, in both foul areas of the region's land is very low. The hydro-electric reservoirs, the main hydrological systems in the water are dead.
On November 17, at the Phu Vinh reservoir, which will provide a & # 39; Most of the water and the production of Dong Hoi (Quang Binh) town, we recorded a low level level level at the bottom of the dam; Works say that the water level is about 5 m lower than its annual average. The water supply for 2018 2019 – 2019 winter-2019 is not sure, there are about 3,360 hectares of hydrological water. According to the Quang Binh Hydro-meteorological Station, from the beginning of the year, all the stations arrived at the stations but 60% of the average water for many years, only in October, only 36% above average many years.
Quang Tri's group has just given a series of hydrotherapy and introduction of disease prevention, water shortage and salinity measures for agricultural production, people living in 2018 – 2019. At this time Here, there is full water In the section there are 1,300 mm, which reach 53% compared to the # 39; average year. As a result, 16 major reservoirs in the Quang Tri area have very little water resources with less than 30% of stored water. Le Quang Lam, director of the Quang Tri Irrigation Department, said the shortage and water in the early spring of 2018 to 2019 is still happening.
The strategies, this year with El Nino's philosophy, risk to heat in the main areas. From now until the end of 2018, there were only one or two of the sounds of tropical diaspora in southern China, but the land was less likely to affect …
The risk of losing the spring spring in winter
According to Mr Vu Van Lan, in the current situation, Song Tran's hydro-electric power has been seeking ideas from organizations to reduce electricity generation to collect water for 2019. "That Hoi Very salted, even the two H.Duy Xuyen areas. We would like to ask Quang Nam to make a management plan for 2019, especially for water irrigation in the area down the river, to save maximum water for the spring of 2019 winter "But it's the danger of the spring's spring in the winter." In the short time, "he said.
The same opinion, Mr Ngo Xuan Additional information in accordance with the lake's operational process, on November 15, A Vuong water was water. However, without a written agreement from the authorities, water power would still have to be able to evaluate the power system. The lack of water for regulation in the future dry season is very hard, stress.
Recently, at the meeting with the Water Resources Regulation (MONRE) Department, the owners of reservoirs of large hydro-electric power in the Quang area Nam also petitioned the relevant authorities to make a record in order Lochs early in lochs. In a worrying case in 2019, the managing authority should implement a proper and operational direction.
According to the Center for Metallurgy and Hydrology (Ministry of Natural and Environmental Resources), at 13 on November 20, the center of tropical dementia (tropical depression) is approximately 300km away from the Middle East of Philippines. east to south east. The tropical climate is expected to be; moving northwest northwest 24 hours in the remainder, which reaches 25 km per hour and may be top.
At 13 o'clock on November 22, the global center was 11.5 degrees wide north and 115.0 east, about 80km east of Eilean Tu Tay (Truong Sa). The Storm range reached the strongest winds 8 – 9, level 11. The area from Quang Ngai to Ba Ria – will affect Vung Tau just for the storm to be dispersed.
In addition, the air was cold with the premature premature introduction of water from Quang Tri to Thuan Binh, Dak Nong, Dak Lak, Lam Dong, north of the continent. South Heavy waters are likely to continue from 23 to 28 November, the heavy rainfall of the Quang Tri areas down to Thuan Binh and the water can reach up to 300-500 mm. AnPhan Hậu)
