The Khuran Channel, Southern Iran (26°45’N), is a topographically complex channel which is open at both ends. Owning to its particular geometry, this narrow channel is subjected to strong tidal currents.Across-channel distribution of the mean and tidal flows were obtained over a semidiurnal tidal cycle in the Khuran Channel where the highest tidal velocity in the third day of the seco...

This course of 15 lectures provides an introduction to open channel hydraulics, the generic name for the study of flows in rivers, canals, and sewers, where the distinguishing characteristic is that the surface is unconfined. This means that the location of the surface is also part of the problem, and allows for the existence of waves – generally making things more interesting! At the conclusio...

Stuff happens. That’s one of life’s rules. Some of it is of profound importance or even historical in nature. Some is routine or of no major significance. The rest depends on who you are, what you are doing, or where you are or where you are going. But, regardless, learning about what’s happening in the world gives us awareness and allows us to assess implications, make decisions, and respond w...

water distribution method based on the type of water conduits can be divided into two groups, namely, open and closed systems, while on the basis of the energy of the water flow, the two groups are gravity flow and pressurized flow. open channel type conveyance and distribution is achieved by gravity and includes channels made by embankment construction, excavation, or construction of prefabric...

During times of lowered sea level, Mekong River and Red incised valleys into the ancient coastal plains exposed shelves western South China Sea. The deglacial fill history valley was investigated by seismic surveys sediment cores. channels mainly exhibit a low-sinuosity course, but some channel segments are bent. oldest part channel-bend exhibits shingled reflectors in Parasound records documen...

Submarine-fan channels can build the largest sediment accumulations on Earth, but our understanding of flow and sedimentation processes related to channel evolution remains limited. Results from physical numerical modelling predict dominantly downstream bend migration. However, observations evolutionary models for aggradational submarine passive margins suggest that bends are dominated by later...

in river meandering, when flow passes through a bend, reduction of flow velocity and rising hydrostatic pressure cause super elevation phenomena at outer side and reduction of water surface at inner-side of the bend. a helical motion results, causing erosion of the outer side of the bend. installation of submerged vanes on the stream bed can reduce erosion of the outer bank significantly. in th...
