—We conducted an intensive fish survey in the tailwater reach of a large Ozark river 30 years after its impoundment and compared the recent fish assemblage with those prior to impoundment and shortly (4 years) after impoundment. Our primary objective was to assess whether relatively short-term monitoring following dam construction can adequately quantify the long-term effects of impoundment on ...

Dam-break flood waves represent a severe threat to people and properties located in downstream regions. Although dam failure has been among the main subjects investigated academia, little effort made toward investigating wave propagation under influence of tailwater depth. This work presents three-dimensional (3D) numerical simulations laboratory experiments dam-breaks with performed at Laborat...

This paper investigates the potential use of composted cotton gin trash (CCGT) as a pesticide sorption medium in remediation of contaminated tailwater. CCGT was found to contain a large organic matter fraction (25.22%). Sorption of endosulfan sulfate and diuron, using the batch equilibrium method, was rapid but not limited for the range of applied concentrations, with diuron failing to reach eq...

Abstract Erhai Lake is a highland freshwater lake in Dali, China. Rapid tourism development has generated large amounts of pollutants. Since 2015, six wastewater treatment plants (WWTPs) have been built to treat collected through sewage interception projects. In this study, reductions the pollution load from different sources were evaluated by considering effects groundwater leakage, microbial ...

In the practice of using river resources accumulated in reservoirs, there is a typical problem unreasonably large water intake for industrial-household needs to detriment aquatic ecosystem. An important tool balancing these links provide environmental flows based on comprehensive analysis functioning patterns. And terms progressing negative impact reservoirs integrity ecosystems, choice indicat...
