Đánh giá ảnh hưởng của các hồ chứa đến dòng chảy trên sông Đà

Abstract

This research evaluates the influence of reservoirs inside and outside the territory on the flow change on Da river to Ta Bu station by statistical method and using HEC-HMS model to simulate natural flow numerically Satellite rainfall data (IMERG) is compared with real measured data (when the reservoirs come into operation) to assess flow changes during the flood and dry seasons and annual flow. The results show that the decrease in the total annual flow when the reservoirs come into operation increases the dry season flow and decreases the flood season flow.
