Research on solutions to increase reservoir capacity, ensuring water security in Thanh Hoa province

On the morning of June 28, the Department of Agriculture and Rural Development and the Thanh Hoa Irrigation Science Association organized a scientific workshop on "Researching solutions to increase reservoir capacity, ensuring water security, serving fast and sustainable socio -economic development in Thanh Hoa province".

Delegates attending the conference.

Attending the workshop were representatives of the Vietnam Irrigation Association, the Thanh Hoa Union of Science and Technology Associations, People's Committees of districts and towns with large reservoirs...

Thanh Hoa has an average total surface water volume of about 20 billion ^m3 /year. Of which, endogenous water is 9.7 billion ^m3 and groundwater in the province is about 0.3 billion ^m3 /year, the rest is exogenous water from Lao PDR and neighboring provinces. The average water volume per capita of the province is about 5,600 m3/person/year, quite low compared to the whole country (9,000 ^m3 /person/year). However, endogenous water volume only reaches an average of 2,665 ^m3 /person/year, while the amount of water that can be proactively used only reaches an average of 1,648 ^m3 /person/year, less than 2,000 ^m3 /person/year (according to the standards of the International Water Association - IWRA). Thus, Thanh Hoa province is at the threshold of a water resources crisis area.

Representative of Thanh Hoa Irrigation Science Association presented a paper at the workshop.

After many periods of development, up to now, Thanh Hoa province has built 2,524 irrigation works, including 610 reservoirs (including Cua Dat reservoir, which is a particularly important national reservoir, managed by the Ministry of Agriculture and Rural Development), 1,023 dams, 891 pumping stations and 14 hydroelectric works. However, many dams and reservoirs built in the 60s and 70s of the 20th century have exceeded the life span prescribed by the design, not ensuring the safety of water storage during the rainy season...

Deputy Head of the Irrigation Sub-Department presented a paper at the workshop.

Faced with the above situation, at the workshop, delegates focused on discussing solutions for effective management and use of freshwater resources in Thanh Hoa province, such as: Investing in new construction of water storage and water regulation works; investing in projects to transfer water from areas with surplus to areas with shortage, areas with frequent droughts, areas with large increases in water use; upgrading degraded water exploitation and use works. Focusing on upgrading to ensure the safety of reservoirs, increasing water storage capacity for lakes with favorable hydrological conditions...

Representative of Vietnam Irrigation Association speaking at the conference.

Also at the workshop, experts introduced urgent issues and basic requirements for ensuring water security, dam and reservoir safety in the current situation. Introduced basic contents of the Planning for natural disaster prevention and control and irrigation for the period 2021-2023, vision 2050, issues related to water security, dam and reservoir safety. Solutions for managing, protecting, exploiting, using and developing water resources to improve the effectiveness of implementing Conclusion 36-KL/TW of the Politburo on ensuring water security and dam and reservoir safety until 2030, vision to 2045. Planning, natural disaster prevention plan and response plan for natural disaster prevention and control of Thanh Hoa province until 2030, vision 2050.
