On the cover: Grain shape may affect the permeability of granular materials. A series of pore flow simulations were conducted focusing on the grain aspect ratio. The aspect ratio affects both the possible range of void ratios and the surface area of packed grains. As a result, the aspect ratio indirectly affects the permeability.

Frequent Reviewer Credit Program
Reviewers who complete five reviews during the calendar year will be eligible to publish an accepted paper during the following year without paying publication charges. Details at http://mc.manuscriptcentral.com/vzj
New Paper Type: Priority Communications
“Priority Communications” are intended to highlight time-sensitive new research results that have far-reaching impacts across the vadose zone community, i.e., "game changers." These manuscripts will undergo the same rigorous peer reviews as other submissions, but the process will be accelerated and the papers will be shorter and more accessible. Instructions for Submission
