Abstract: A simple shear flow of granular materials can have a range of behavior from a rate-independent plastic material to a rate-dependent viscous material. From physical experiments and computer simulations, it is known that ...

Abstract: A theory for determining the onset of rapid flow or termination of quasi-static flow in a cohesive granular material mixed in a viscous interstitial fluid is presented. This theory is based on a one-dimensional model ...

Abstract: In this paper we discuss teaching fluid mechanics to civil and environmental engineering majors at both the undergraduate and graduate levels. Fluid mechanics is a key course in environmental engineering that ties together ...
