ISAR Virtuaeolian Seminar Series

The Board of ISAR has been considering options for an on-line series of presentations by member of our aeolian community. In part to soften the disappointment of not meeting in Namibia this year, but also to maintain links with members between ICAR meetings and to share recent work and findings in aeolian science.

 

We are very pleased to announce that Professor Doug Sherman, The University of Alabama, one of our most respected and dedicated members, has kindly agreed to offer a seminar that explores aspects of a paper he recently published.

 

Sherman, D. (2020) Understanding wind-blown sand: Six vexations (https://doi.org/10.1016/j.geomorph.2020.107193)

 

The title of Doug’s talk is: Deconstructing q: the empirical barriers

 

Abstract: We understand the fundamental controls on wind-blown sand transport rates for ideal or near ideal environments. Decades of experiments, however, have failed to bring us to agreement on the correct formulation of the relationship between those controls even with tightly constrained conditions, and this disagreement is a form of error. The focus of this presentation identifies several sources of such error associated with empiricism, including: measuring the threshold of motion; measuring moisture effects on the initiation of motion; measuring transport rates; and rationalizing wind tunnel studies with field studies. This is a familiar laundry list, but one worthy of another washing.

 

I know this talk and the subsequent discussion will be of interest to ISAR members and we warmly invite you and your colleagues to participate.  

 

Register in advance: https://otago.zoom.us/meeting/register/tJMpdOCoqjgjHdJkbO9yPYLv01RKx5WYwy2u

After registering, you will receive a confirmation email containing information about joining the meeting.

 The talk is at 1pm local time for Doug, which equates to:

Toronto, Canada                      Thu, 12 Nov 2020 at 14:00    EST

 

It will be early morning for the convenors, in the Antipodes, so we’re arranging for someone closer to Doug’s time zone to chair the meeting.

 

Finally, we would welcome nominations and volunteers for seminars later in the year and through 2021, including proposals from early-career researchers and panel discussions.

 

Best wishes from myself and Dr Graziela Miot da Silva, Flinders University
