According to the Institute of Irrigation Science in the Central and Central Highlands, on March 22, the water quality monitoring results of the Vu Gia-Thu Bon system were used to allocate water for production in the 2023 winter-spring harvest in Quang Nam province collect and the city of Da Nang for It was found that at the time of the monitoring, the pumping stations of Mieu Ong and Tuy Loan were not affected by salinity, allowing water to be used to irrigate rice.

In particular, at the site of the Tu Cau pumping station, since no temporary dam was built to prevent the salinity, the salinity continued to increase compared to the previous week at the time of monitoring (11 a.m. on March 22) was 2.4 ‰. Regarding water quality, it was shown at the water quality monitoring sites that the monitoring indicators at the sites were within the allowable limits for irrigation water supply.

Currently, rice is produced in Quang Nam Province and Da Nang City. An Trach’s irrigation system works according to the approved method.

According to the calculation results of the Institute of Irrigation Science in the Central and Central Highlands, the water quality forecast for the next week (from March 24 to March 31) at all measurement points will meet the requirements for irrigation water quality, especially for agriculture At the site of the Tu pumping station Cau (VT6) salinity tends to increase, water quality decreases sharply, some water quality indicators exceed the allowable limit and may affect water quality. Currently, the rice in the region is in the growth phase and needs a lot of water to grow, so it is necessary to have a plan to ensure water supply for irrigation, both in terms of source and quality. During the operation of a Trach system, the responsible units should observe the following:

Quang Nam and Da Nang Ministries of Agriculture and Rural Development must pay attention to ordering the Irrigation Subdepartment and Irrigation Exploitation Society to monitor saltwater intrusion and water quality to proactively adjust solutions to promptly provide water for winter – to deliver spring crops.

For Da Nang City and Quang Nam KTTL One Member Limited Liability Company, it is necessary to strictly manage the water sources and ensure irrigation for the areas in the system; Instructing units to monitor water level changes, strictly follow the tide schedule, hydroelectric power plant discharge schedule, and salt water intrusion schedule to establish an operation plan to ensure safe water supply for hydroelectric power plants.

In addition, the relevant authorities must continuously update and regularly provide information on salt intrusion and water quality in order to proactively adjust timely and effective response solutions. Guidance on how to implement measures to reduce salinity and save on irrigation.
