Designing Manhole in Water Transmission Lines Using Flow3D Numerical Model [PDF]
Civil Engineering Journal, 2015 Using cascades and drops existing in flow path has a history of 3000 years. Particularly, Roman engineers employed stepped spillways with the same idea in several countries; however, there are few information about the hydraulic performance of aqueducts.

Design, construction, and preliminary hydraulic evaluation of a model rock ramp fishway
North American Journal of Fisheries Management, Volume 43, Issue 4, Page 935-946, August 2023., 2023 Abstract Objective New fish passage structures are frequently designed using information gained from existing structures, particularly those that have been shown to allow passage of the target species. However, this process rarely involves a preinstallation design and testing phase.

River, Volume 1, Issue 1, Page 91-103, August 2022., 2022 Abstract Many slow‐moving landslides in the Three Gorges Reservoir (TGR) area exhibit episodic movement patterns in response to variations in the reservoir water level and seasonal rainfall. These landslides are typically characterized by pre‐existing shear zones composed of thick, clay‐rich layers that are sensitive to hydrological forcings.

Simulation of Flow Suspended Load in Weirs by Using Flow3D Model [PDF]
Civil Engineering Journal, 2015 Sharp-crested weir and side-channel weirs can be considered among the control and flow-measuring structures which are greatly applicable in channels, dam spillways and other hydraulic structures. Discharge coefficient in these two types of weirs is affected by the structural geometry and the hydraulics of the flow.

Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 The jet flipped from flip buckets hits the dam’s downstream side as a free jet with an immense amount of energy, leading to bed erosion. Erosion of river bed materials downstream of dams could affect the performance of dams or power plants by altering the tailwater depth, rendering proper designs of controlling structures or erosion reduction methods ...
