Dam release is one of the important measures in managing and regulating water resources in irrigation and hydroelectric works. The effects of dam release are clearly demonstrated through many different aspects, especially in minimizing the risk of natural disasters, providing water for agriculture, and maintaining the ecosystem.
First of all, dam release helps reduce pressure on dams when water levels rise, especially during the rainy and flood season. When the water flow exceeds the safe level, if water is not released, it can lead to the risk of dam failure, causing major flooding downstream, causing damage to people and property. Dam release regulates the flow in a controlled manner, helping to minimize sudden flooding.
In addition, dam release also provides water for irrigation activities in agriculture. Many downstream areas depend on water sources from reservoirs and irrigation dams. Timely and sufficient water release will ensure the water needs of crops, while stabilizing agricultural productivity. In particular, during dry periods, releasing water from dams also helps reduce water shortages, ensuring livelihoods for people.
Environmentally, dam releases play an important role in maintaining natural flows, creating favorable conditions for the development of aquatic ecosystems. When the water level in dam reservoirs is too low, releasing water will help maintain a reasonable water level for rivers and canals, creating a stable living environment for many species of animals and plants. In addition, the water after release also helps push away waste and sediment, clean the riverbed, and improve water quality.
However, dam releases need to be carried out carefully and planned to avoid flooding downstream. Close coordination between management agencies and localities is essential to ensure safety and efficiency. If not well controlled, sudden dam releases can cause unwanted consequences such as washing away crops and destroying infrastructure.
In summary, dam releases bring great benefits to people and the environment. They not only help regulate water flows and reduce the risk of flooding, but also support agricultural production and protect ecosystems. However, to ensure safety and maximize efficiency, strict management and supervision of water releases are required.
