A list of all pages that have property "Extended movie description" with value "The HSTAR model is developed to investigate the morphological change in large-scale river systems. It uses the shallow water equations and nested sediment transport and erosion algorithms to control the changes in the river due to varying water transport. The model has a unique ability to mimick the growth of vegetation on river bars that are not inundated anymore. This simulation runs for 350 years (in modeled time) and you can see the river system evolve. This simulation is set up for a coarse-grained sediment (grainsize 0.4 mm). In the simulation mid channel bars form and persist. This pattern is commonly observed in nature (perhaps a close example is the Brahmaputra river). You can also see bar migration, compound bar evolution (where bars are merging). New deposition happens in the leeward side of vegetated bars, where flow velocities are lower. These simulations have a feedback between the growth of vegetation and bar accretion- the vegetated bars will experience slower flow rates and thus more sediment can settle on top of them.". Since there have been only a few results, also nearby values are displayed.
