Laboratory investigation of the effect of using riprap and vegetation on the scour around the bridge abutment [PDF]
فناوریهای پیشرفته در بهرهوری آب, 2022 One of the most important factors of damage and failure of hydraulic structures is the occurrence of local scouring around them. Scour is a natural phenomenon that occurs due to the flow of water in rivers and streams.

Experimental Study of Sedimentary Interflow Density Current Body Height in Separation Point From Bed [PDF]
علوم و مهندسی آبیاری, 2018 Underflow density currents traveling through density-stratified fluids begin to separate from the bed as they reach areas of similar densities, after which they continue their path as interflows through the surrounding ambient fluid. This point, which is

Analyzing the flow pattern changes caused by installing inclined plates upstream of bottom outlet using numerical simulation [PDF]
فناوریهای پیشرفته در بهرهوری آب, 2023 The low inflow rate of water into the dam reservoirs causes sedimentation, leading to a decrease in the service life of dam. As a result, the performance of the dam in controlling floods and generating energy through water release downstream will be ...

A three-dimensional numerical model to estimate the fall velocity of sediment particles [PDF]
Journal of Advances in Environmental Health Research, 2019 The fall velocity of sediment particles plays a key role in sediment transport studies. Researchers have attempted to determine the terminal fall velocity, and most of the studies in this regard have been based on experimental, quasi-experimental, and in-
