SUMMARY:CFSF Lunchtime Science Seminar
DESCRIPTION:\nPlease join us next Wednesday February 19th from 12-1pm MDT via Zoom for our first installment of our new Clark Fork Science Forum monthly webinar and discussion series. Our first speaker will be Dr. Payton Gardner from the University of Montana Department of Geosciences. Dr. Gardner will present his research titled, “Estimating Groundwater Gain and Loss Along the Upper Clark Fork Using Non-Applied Tracers.” A full description of this exciting research is below as well as a Zoom link for joining the presentation. Grab your lunch and join us!\n\n\n\n\n\n\n\nEstimating Groundwater Gain and Loss Along the Upper Clark Fork Using Non-Applied Tracers\n\n\n\nDr. Payton Gardner, Department of Geosciences, University of MontanaIn this talk, I explore the use of synoptic surveys of environmental tracers and stream discharge to quantify stream loss, gain and net exchange along the Upper Clark Fork between Warm Springs Pond and Deer Lodge. Estimating integrated stream gain and loss from/to the subsurface over long reaches is challenging. Current measurement methods require injections of applied tracers, or are point-based, are mostly limited to hydraulic gradient and/or temperature profile time series and are difficult to upscale. In this talk, I develop a new interpretation method for synoptic surveys of stream and ground water concentration and stream discharge of non-applied (environmental tracers) and use that method to quantify the location and amount net exchange, groundwater gain and loss along a 47 km reach of the Upper Clark Fork. Groundwater loss from the river to the alluvial groundwater system dominates along the upper 20 km below Warm Springs. Groundwater gain from the alluvial system to the stream dominates the lower 20 km. These results provide an initial survey of integrated groundwater exchange in Upper Clark Fork and illustrate that synoptic sampling for environmental tracers and discharge is a powerful method for detecting and quantifying groundwater discharge (gain) to streams over 1-100 km length scales.\n\n\n\n\n\n\n\nZoom Information\n\n\n\nTopic: Clark Fork Science Forum – Lunchtime Science Seminar Reboot!Time: Feb 19, 2025 12:00 PM Mountain Time (US and Canada)Join Zoom Meetinghttps://us02web.zoom.us/j/88170062525?pwd=C2Nbxb9NCzElLR35vdyRwCjP3B3jM8.1 ( https://us02web.zoom.us/j/88170062525?pwd=C2Nbxb9NCzElLR35vdyRwCjP3B3jM8.1 )\n\n\n\nMeeting ID: 881 7006 2525Passcode: 618560\n\n\n\n\n\n\n\nOne tap mobile+12532158782,,88170062525#,,,,618560# US (Tacoma) +13462487799,,88170062525#,,,,618560# US (Houston)\n\n\n\n\n\n\n\nDial by your location\n\n\n\n\n+1 253 215 8782 US (Tacoma)\n\n\n\n+1 346 248 7799 US (Houston)\n\n\n\n+1 669 444 9171 US\n\n\n\n+1 669 900 6833 US (San Jose)\n\n\n\n+1 719 359 4580 US\n\n\n\n+1 253 205 0468 US\n\n\n\n+1 386 347 5053 US\n\n\n\n+1 507 473 4847 US\n\n\n\n+1 564 217 2000 US\n\n\n\n+1 646 931 3860 US\n\n\n\n+1 689 278 1000 US\n\n\n\n+1 929 205 6099 US (New York)\n\n\n\n+1 301 715 8592 US (Washington DC)\n\n\n\n+1 305 224 1968 US\n\n\n\n+1 309 205 3325 US\n\n\n\n+1 312 626 6799 US (Chicago)\n\n\n\n+1 360 209 5623 US\n\n\n\n\nMeeting ID: 881 7006 2525Passcode: 618560\n\n\n\nFind your local number: https://us02web.zoom.us/u/kdPoXjkmCF ( https://us02web.zoom.us/u/kdPoXjkmCF )\n\n\n\n\n
