Water Accummulation Analysis in HEPA Watershed, Huong Son District, Ha Tinh

• There are many methods that can be used for assessment of water resources for an area, however, no method is considered omnipotent. Each method has its own advantages and disadvantages. The HEPA study area is a small area, with relatively primitive conditions, not much affected by humans. Data and documents related to this area are very limited, while time and human resources are limited. Therefore, the report used hydrological methods to calculate the water balance for the area. Hydrological methods are considered one of the simple, but quite effective methods. The method makes good use of existing hydrometeorological data, and at the same time evaluates the components in the water balance equation quite thoroughly. The calculation results were performed for two scenarios, the current situtation and when considering the level of forest degradation. Although the total amount of water did not change in the two scenarios, each component changed, showing the contribution of forests to the redistribution of water resources. This research is only considering the vertical water balance equation. In fact, the role of forests also affects spatial and temporal changes, especially the ability of forests to regulate flow in reducing high flow and increasing low flow. To evaluate the effectiveness of forests on water resources, further in-depth research is needed.
