Landscapes Live Thursday 25th February: Allison Pfeiffer

 Dear all,

We are very pleased to announce our third “Landscapes Live” online seminar of 2021 by Allison Pfeiffer (Western Washington University) that will occur this week on Thursday 25th February at 7 am PST / 10 am EST / 3 pm GMT / 4 pm CET on:

“Sediment supply controls river bed (in)stability in the Pacific Northwest ”

Abstract: Gravel river channel beds aggrade and incise through time via the process of coarse sediment transport and in response to temporal variation in the upstream supply of water and coarse sediment. However, we lack a thorough understanding of which of these (high flow events or sediment pulses) is the dominant driver of channel bed elevation change. This lack hampers flood hazard prediction, as changes to the bed elevation can either augment or reduce flood heights. In this talk, I will explore the drivers of channel change using multidecadal time series of river bed elevation at 49 United States Geological Survey (USGS) gauge sites in the uplands of Washington State, USA. 


This seminar will be live on Zoom and open to anyone interested (with a limit of 300 participants). You can register in advance for this Zoom meeting here:

The Landscapes Live online seminar series will then continue the following weeks with:

  • Thursday 4th March at 3 pm GMT/ 4 pm CET: Karl Lang, Georgia Institute of Technology
  • Thursday 11th March at  3 pm GMT/ 4 pm CET: Ajay Limaye, University of Virginia
  • Thursday 18th March at 3 pm GMT/ 4 pm CET: Roman DiBiase, Pennsylvania State University   
  • Thursday 25th March at 3 pm GMT/ 4 pm CET: Simon Mudd, University of Edinburgh     

Previous talks are available on the website (https://osur.univ-rennes1.fr/LandscapesLive/). We are already planning a second seminar series this spring. Feel free to contact us if you have questions or suggestions: landscapesliveseminar@gmail.com

Landscapes Live is the EGU Geomorphology Division's virtual webinar series focused on sharing exciting geomorphology research throughout the international scientific community.

Best wishes,

Introduction to Critical Zone Observatories and Watershed Sites.

  Dear Watershed Science Community,   The  Early career network-of-networks team  is pleased to announce the Fall 2021 Webinar series on  Introduction to Critical Zone Observatories and Watershed Sites . This webinar series hosted by CUAHSI will occur every Tuesday from August 24 till September 28 at 9:00 AM Pacific Time. The goal of the series is to discuss ideas and brainstorm on ways to enhance collaboration and integration across different international critical zone observatories and watershed sites. The webinars will include several researchers from watershed science and critical zone communities. Read more about this effort  here .   The first webinar will be held on  August 24th, 2021  9 am Pacific and provide an introduction to the montane sites across the world. Confirmed speakers for the first webinar include Susan Hubbard (Berkeley Laboratory), Holly Barnard (CU Boulder), Steven Holbrook (Virginia Tech), Antonello P...

Isotope Tracers in Catchment Hydrology

  We are once again running our Isotope Tracers in Catchment Hydrology course, designed as a national graduate level course (accessible to all Canadian students for credit), but also available to professionals. The course will run from May 10 through 14 online. All of the details pertaining to the class can be found on our class website:  https://water.usask.ca/hillslope/teaching/isotope-tracers-in-catchment-hydrology.php   All are welcome, and participants from outside academia and Canada are encouraged to enrich the discussion.   Hope to see you there, Trish (on behalf of course instructors)   Dr. Tricia Stadnyk, P.Eng.
