Bridges when it crossing rivers often required multiple piers for support. One of has a limited investigation is the impact on scouring and morphological aspects bridge sharp-bend river. Consequently, crucial to investigate hydraulic behavior water flow in these areas due presence piers. In present study, an experimental program was conducted laboratory flume featuring two-pier within 180-degre...

Plastic litter transported in rivers may enter the marine environment. Due to durability of plastic, residence times aquatic environment are decades millennia. items come a wide variety. The density item and flow velocity largely determine vertical distribution plastic litter, although shape wind can also play role river. Estimates transport river usually based on observations visible near-surf...

The Sulaiman Fold Thrust (SFT) in Central Pakistan formed during the India-Eurasia collision late Cenozoic. However, mechanics of shortening brittle crust at time scales seismic cycles is still poorly understood. Here, we use radar interferometry to analyze deformation associated with 2015 magnitude (Mw) 5.7 Dajal blind earthquake eastern boundary SFT. We kinematic inversions determine distribu...

Investigating the features and flow behavior and related component is one of the complex phenomena that make using of software inevitable. The rivers carry sediment content along with water which is created by erosion of riverbed sediment and erosion caused by rainfall or surface runoff flowing over the catchment area. If the action of river dewatering occurs, the entry of sediment into the int...

[1] The paper investigates the influence of relative bend curvature on secondary flow, energy losses, and turbulence in sharp open-channel bends. These processes are important in natural streams with respect to sediment transport, the bathymetry and planimetry, mixing and spreading of pollutants, heat, oxygen, nutrients and biological species, and the conveyance capacity. Laboratory experiments...

[1] On the basis of a 301 day acoustic Doppler current profiler mooring in an estuarine tidal strait the strength and structure of secondary circulation in a region of flow curvature is related to variations in tidal forcing and river discharge. During low-flow conditions the structure of secondary flow is consistent with a centrifugally forced helical flow, with bottom flow toward the inside o...

The Ikeda, Parker, and Sawai river meandering model is reexamined using a physical approach employing an explicit equation of motion. For periodic river shapes as seen from above, a cross-stream surface elevation gradient creates a velocity shear that is responsible for the decay of small-wavelength meander bends, whereas secondary currents in the plane perpendicular to the downstream direction...
