The studied used the GLOBE Protocol methodology. to study water transparency, water temperature, dissolved oxygen, water conductivity, water salinity, water acidity, water alkalinity, nitrate content and data recording in the Data entry system.
Research results
1. Compared the properties of water in 2023 and 2024, it was found that the
properties of water had greatly changed In 2024, the water level rose to the edge of the pond, making it impossible to measure transparency. The water temperature dropped by 3 degrees Celsius from previous year. The conductivity of water increased by 80.5 µS/cm and the fullness decreased to 0.3 ppt. pH Value were measured at 7, the alkalinity was measured at 109 mg/l, which was lower than the previous year. The nitrate content was 0.02 ppm, and the dissolved oxygen content was 5.25 mg/l, which was lower than the previous year.
At the beginning of 2024, the Meteorological Department announced that Thailand would enter a La Nina phenomenon. The occurrence of La Niña causes environmental changes that affect the water properties in the Varee Basin as follows:
2. Compared the amount of dissolved oxygen in water in 2024, it will decrease to 5.25 mg/l because the water level in 2024 is very high. Cloudy water it is impossible to measure the transparency. This may result in a decrease in photosynthesis of plants in the water, resulting in a decrease in the amount of oxygen dissolved in water.
3. Compared the conductivity of water, it was found that in 2024, the conductivity increased by 80.5 µS/cm. The increased amount of water in the reservoir because it very higher rainfall than in 2023. And water from other water sources in the Somdet community flows together at the varee Reservoir, resulting in a greater amount of substances that break down to electrons, which may result increase in the conductivity of the water.
