The two major flow mechanisms in the vadose zone are uniform flow and preferential flow. Both types of flow occur often simultaneously, but have considerably different consequences for water flow and ...

Most previous studies of chaotic advection have focused on two-dimensional (2D), time-periodic flows. Transport barriers are prevalent in those flows 6; in fact, chaotic transport barriers have been ...

Chezy and Manning developed equations that are used to determine the average volumetric flowrate in open channels. This article explains a laboratory method that was developed and tested to further ...
