  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

  Dear All,   The Oxford Water Network and Oxford Hydrology Group warmly welcome you to their termly lecture:   Investigating common assumptions about hydrologic modelling in a large-sample approach. Speaker:   Dr Wouter Knoben --Postdoctoral Fellow, University of Saskatchewan, Canada Date:   3 rd   March, 16:00-17:00 GMT Registration Link:   https://www.eventbrite.co.uk/e/investigating-common-assumptions-about-hydrologic-modelling-in-a-large-samp-tickets-138762372993     About the Event   This study uses 36 conceptual hydrologic models calibrated to streamflow observations in 559 catchments across the United States to investigate differences and similarities in model performance. Central in this talk is the common approach to setting up hydrologic models that uses separate calibration and evaluation periods and a single objective function to quantify model performance. We investigate this topic from multiple angles and show that several common, and sometimes implicit, assumptions in t

  Dear all, We are very pleased to announce our second   “Landscapes Live”  online seminar of 2021 by   Edwin Baynes (Loughborough University) that will occur this week on   Thursday 18th February at   7 am PST / 10 am EST / 3 pm GMT / 4 pm CET   on: “Hard vs Soft: spatial variability in bedrock channel geometry driven by sediment availability” Abstract: Sediment supply is a key role in the physical processes that drive erosion and sedimentation in bedrock and mixed gravel-bedrock rivers. In this talk, I’ll show the direct impact of the supply of coarse‐grained, hard sediment on the geometry of (soft) bedrock channels from the Rangitikei River, New Zealand. Channels receiving a coarse bedload sediment supply are found to be systematically (up to an order of magnitude) wider than channels with no bedload sediment input for a given discharge. I’ll also explore this phenomenon using analogue model experiments of a bedrock river reach under different sediment supply conditions, before comp

Dear colleagues,    We would like to invite you to the “Water Challenges in a Changing World” seminar series of Institute of Global Innovation (IGI) at Birmingham. The series of online seminars offers interdisciplinary perspectives on global water challenges by a field of international research leaders in the run-up to the UN World Water Day ( https://www.unwater.org/what-we-do/inspire-action/ ) on 22 March 2021 (with next year’s theme being on “Water2me”).   We are pleased to announce our   fifth   seminar of the “Water Challenges in a Changing World” series on   16 th  February   (12-13hrs GMT)  by   Prof Harry Dixon   ( https://www.ceh.ac.uk/staff/harry-dixon )   of   the   UK Centre of Ecology and Hydrology,   who will be talking about:     Prof. Harry Dixon   “Innovation in operational water monitoring“       Please use the login instructions below for this webinar to be hosted in ZOOM     We are looking forward to welcoming you for  Harry’s  and all the forthcoming talks of this

  CONTACT:   Tina Buxbaum, 907-474-7812,   tmbuxbaum@alaska.edu Recent drought in Southeast Alaska has challenged people living and working in the region. But drought can affect all of Alaska, with impacts on wildfire, snowpack, glaciers, agriculture and subsistence resources. These topics will be discussed starting Feb. 16 in a free seven-part virtual series hosted by the University of Alaska Fairbanks and the U.S. Department of Agriculture Northwest Climate Hub. Register at   https://tinyurl.com/AK-Drought   to receive the Zoom link, or attend via the   International Arctic Research Center Facebook page . “Recent years we have seen some quite dramatic precipitation extremes in Southeast Alaska, both on the dry and wet side,” said Rick Thoman, Alaska climate specialist. “Is what we are seeing in the recent past indicative of the future?” Thoman will lead the first discussion on Feb. 16 at noon. He will explore unusually dry times in Alaska’s past. He will also provide a statewide over

Dear Geomorphologists, We're pleased to announce that registration is now open for the IAG's regional webinars: ~half-day online events to celebrate International Geomorphology Week   #IntGeomorphWeek2021 . The eleven webinars are being held in a wide range of time zones across the world with the aim to highlight new talents and emerging themes across the geomorphological community. Places are limited so we'd encourage you to register now to secure your place - if capacity is reached then the events will be livestreamed. More details on these webinars, link to registration and a listing of other events being held to celebrate   #IntGeomorphWeek2021   can be found on our website (continually updated so please keep checking):   http://www.geomorph.org/international-geomorphology-week-2021/ Hope to "see" you at one of the webinars!

  The next webinar of the 3 rd   Arctic Science Ministerial (ASM3) Webinar Series will focus on Theme 2: Understand.  An overview of progress in enhancing our understanding and predictive capabilities since ASM2 will be shared as well as new projects and activities on the horizon.  This will be followed by a series of short presentations highlighting a few observation projects submitted by ASM3 participating countries and organizations. Recommended Actions to increase understanding of the Arctic and international collaboration will be presented. A short Q&A will follow. For the full webinar programme and registration information, please visit   https://asm3.org/webinar-series/ .   The webinar series is a joint cooperation between the ASM3 Organizers in Iceland and Japan, and the European Polar Board. -----------------------   Joseph E Nolan Policy Officer European Polar Board   NWO, Laan van Nieuw Oost-Indië 300 2593 CE The Hague, Netherlands Phone: +31 (0) 703440584 Email:   j.nol

Folks, After much help from others, we have settled on a plan to hold an on-line  Gilbert   Club  meeting (representing 2020!).  The details are below.  It will include the usual GC elements- a roll call, presentations from JGR editor (Amy East) and NSF (Raleigh Martin), pop ups, and this year, a single speaker- Suzanne Anderson (who was awarded the AGU Earth and Planetary Surface Processes G.K.  Gilbert  Award in 2020).  You can see that there is an emphasis on community (roll call, pop ups, and, at the end, an invitation to a Wonder room to “socialize” as best one can on-line).  At the choice of the individual contributor, the pop ups will be posted and open to all, otherwise their video will only be shown at the time of the meeting.   We will set up  a web page where examples of  Roll call videos will be posted and you will be invited to upload your video and a video of a Pop up, should you chose to do so.   Please look for the next announcement for specifics regarding access to the
