Abstract
Physics-based computer models are widely used in civil and environmental engineering. In the area of river mechanics, many problems involve the complex interactions among flowing water, sediment, and objects (structures). The dynamics and evolution of such coupled fluid-object-sediment systems are of great interest to civil engineers and applied mathematicians. However, due to the complex nature of the coupled physical processes, it is very challenging to build a deterministic computer model. Governing differential equations for all relevant physical processes (turbulent flow, sediment particle transport, granular material behavior, and object motion) need to be solved properly on a dynamically changing domain. This talk will show some progress we made to tackle such difficult problems. The direct application is to predict the fate of underwater objects. However, the computer model developed can be applied to many other similar systems.
