Abstract: A piping model based on Darcy's law is developed. An analysis of data pertaining to different soil particle sizes and varying porosity shows that the choice of the permeability function is critical for the piping model. ...

Abstract: One of the main mechanisms of failure of levees is a phenomenon called “piping,” which generally begins with the formation of a sand boil at the leeward side of the levee, and has been frequently observed to proceed upstream ...

Abstract: Using a new channel shape equation for straight channels and a more versatile channel shape or local flow depth equation for natural streams a method is developed for prediction of the longitudinal dispersion coefficient ...
