So happy our paper in @NatureGeosci is finally published! We discovered a new origin for the initiation of drainage basins, where river avulsions leave constructional ridges that form drainage divides, and basins can form and evolve quickly. @txgeosciences @BenoftheSand
Article: Drainage divides between coastal plain channel networks can be constructed through depositional, rather than erosional, processes https://t.co/LFmCHRXBVZ

Exciting presentation by Rob Hollis on the building of a geologic framework in coastal Louisiana to inform coastal management! Great few days at Coastal Sediments 2023 @TheH2OInstitute

Water connects us. 🌎 SWOT will make the first global survey of the water on Earth's surface, monitoring levels of rivers and lakes and examining small-scale ocean currents, helping us see our watery planet like never before. 🚀 Tune in for launch: https://t.co/KZzn4QJZG6

Here's some more information about the Bay Denesse Living Lab. The purpose of the Lab is to foster imagination and creativity in coastal restoration. And to give researchers, practitioners and educators a common place to work.

I'm so happy to see the photos of @UofNo students in this thread by @SeddyRocks! The students in @fostinez's class installed custom designed experimental sediment retention structures. It's the kind of experiment that the Bay Denesse Living Lab is built for. @theH2oInstitute
I had a SUPER time in the field on Friday with With @TheH2OInstitute @fostinez @UofNO! It was my first time on the #MississippiRiver! Also first time IN the water 😂 I have some cool things to share: 🧵1/8

Interested in nature based solutions to flood risk and water infrastructure projects? Want to expand how we value nature, equity, and community benefits in planning? Great summit by a wonderful team
Registration now open for “Measuring What Matters” summit to be held on Nov. 30, both virtually and in Washington, D.C. More information here https://t.co/rq3jx9KeCW and register here https://t.co/dM6mNUkHzX

Wonderful reporting on a tragic challenge- one that is growing exponentially and on all climate issues. Who’s community is relocated? Who will get protection from storms and flooding?

This amazing video captured by San Bernardino county public works - watch all the processes of a #debrisflow of the El Dorado scar September 12, 2022 - heavy rain rates on scar at 8000 feet in 1 hour

“There is no sign of the mangroves that, after a decade of growth, should be close to maturity. An on-the-ground study published in 2020 found that fewer than 2 percent of them had survived. The other 98 percent had died or were washed away.”

High-profile initiatives to plant millions of trees are being touted by governments around the world as major contributions to fighting climate change. But scientists say many of these projects are...

Ongoing disruptions to commerce along the MS river: serious need to better predict and manage sediment + water in the river to minimize risk
Drought threatens commercial traffic and drinking water supplies along Old Man River: “Ultimately, we need rain, and lots of it.” @ssdance

Very overlooked risk to communities and infrastructure systems on the MS- emergency sole source contract for sill construction was issued yesterday to impede further salt encroachment! Low water also likely to hinder navigation and force dredging

Challenges to accessing and using commercial EO data as an NGO or small government- licensing and cost models are a total mismatch to budget and needs, fascinating talk by the panel @WorldBank, dev global, place, @NASAEarthData #SatSummit2022 , @sat_summit

Interesting work by @worldbank standing up an EO and global data group for disaster recovery and climate resilience planning: localization and co-creation of geospatial data with communities and stakeholders builds tremendous sustainability and value #satsummit22 @sat_summit

Great panel on the uses of EO across climate resilience, risk, and global development! Common theme of how COVID drastically impacted development goals and accelerated shifts in approach @sat_summit @WorldBank @USAID #SatSummit2022

Thrilled to be attending #SatSummit2022 for the first time! I’m giving a lightning talk on harnessing open source data streams for predicting river navigation hazard and potential links to EO data- excited to meet new people and learn a whole lot!

Wonderful talk on the management and future of large rivers by @HurryOnPond today at @TheH2OInstitute - tackling the human components head on rather than treating systems as pristine. How will sed budgets, infrastructure, and risks change? Also, stroopwaffle to ton conversions!

I am looking to recruit two master students for Fall 2023 (can start as early as Spring 2023) at @utrgv Available funding is not tied to any one project, so students can develop their own science in the broad theme of surface processes. Admissions are rolling. please RT❤️

Proud of this work led by @ColeSpeed- we show the preservation of significant sand-rich fluvial channel belts in the inner continental shelf strata. These help constrain past river behavior but also may hold restoration quality seds for coastal resilience.
Subsurface fluvial deposits as viable repositories of sediment for coastal restoration? 'Seismic expression and stratigraphic preservation of a coastal plain fluvial channel belt and floodplain channels on the Gulf of Mexico inner continental shelf' https://t.co/0QQAkHiD0c
