Modeling in ice-covered rivers is limited due to added computational complexity, specifically challenges with the collection of field calibration data. Using River2D, a 2-dimensional hydrodynamic modeling software, this study simulates depth-averaged velocity and shear stress distributions under ice cover open-water conditions during varying flow small, shallow riffle-pool sequence. The results...

Water regulation and flood control of rivers are changing due to streamflow depletion following industrialization urbanization, significantly impacting aquatic ecosystems. Therefore, restoration the ecological environment is necessary maintain a healthy river ecosystem. For ecosystem restoration, amount discharge from dams must be controlled appropriate environmental flow calculated according f...

Rivers are among the ecosystems that have been most damaged by human pressure, especially in European countries where most streams are regulated. An important instrument to mitigate such impacts is to provide adequate ecological flows, which allows for the preservation of fish populations. Nowadays, many rivers are invaded by exotic species that, being more opportunistic and tolerant, are chang...

Recent ecological stream restoration projects have focused on expanding the water-friendly space of streams, promoting health aquatic ecosystems, and restoring various habitats, which raise need for relevant research. Applying integrated environmental analysis, this study quantifies change in hydraulic characteristics before after through physical habitat simulation links results impacts to est...

The Chinese sturgeon, Acipenser sinensis, is an anadromous species that spawns in the Yangtze River and Pearl River of China. Its population has declined dramatically since the construction of the Gezhouba Dam (GD) in 1981 and then with the impoundment of the Three Gorges Dam (TGD) upstream of the GD in 2003. This paper presents a quantitative method based on the instream flow incremental metho...
