I'm a postdoc sedimentologist/stratigrapher/geomorphologist currently focused on coastal and river dynamics.

@a_owen0917 @HoosierRiver @AvulsedCanuck @stephan_geo @CaitlinSifuent1 For sure! And we can't thank you enough for sharing coordinates for amazing outcrop exposures. Finding specific sites for so many full Salt Wash exposures would have taken *at least* one full, additional field campaign! Would love to field trip with you out there some day!

Check out our new paper showing how the stratigraphic architecture of #fluvialfans is shaped by downstream changes in #avulsion style. Great mix of outcrop, remote sensing, and modeling with @HoosierRiver @AvulsedCanuck @stephan_geo and @CaitlinSifuent1 https://t.co/RTiZd3Jd1X

Excited to see our recent research on mud-induced meandering spotlighted in AGU's Eos magazine! A big thanks to @bdzombak for some great science news reporting! @DrAlexWhittaker @AGU_Eos #AGU #Proterozoic #meandering #rivers

@RobertCMahon Although, I could *almost* understand if they were there to pick up a sandwich from Pickles and Swiss... so good 😋😂

[Jeff Valenza @ValenzaJeff]

Excited to share our research on Proterozoic rivers- how muddy banks could have supported a variety of channel planforms (even meandering!) in the absence of vegetation. Thanks to collabs Vamsi Ganti, @DrAlexWhittaker, and Mike Lamb! https://t.co/Bfx8KNlrKo

This research is now accepted in @NatureComms ! 🙂Watch this space for our work quantifying ancient floods in Welsh Carboniferous rivers for the first time⚒️🏴󠁧󠁢󠁷󠁬󠁳󠁿⛈️

Standing waves during a flood of Greenwood Canyon near Gila, New Mexico yesterday - many roads washed out and residents (including my sister) not able to leave the area. Luckily they are safe and dry but I’m sure there are many injuries/damage

[Jeff Valenza @ValenzaJeff]

@sineadlyster @jonah_spike As Alex would say, it we had VERY Scottish weather yesterday 😂 But today was great, only a few passing drizzles(?) but otherwise dry. I think it rained 7 or 8 times on us yesterday... paying my dues to claim UK field experience?

Perplexing seaside outcrop of 1.2Ga fluvial sediment… Bar accretion and odd scale cross-stratification; ripple marks; mud desiccation cracks; sedimentary structures at odd parts of the bedform phase diagram! 🤔🏞🌊

New paper is up! Analysis of 13 progradational avulsions in Andean and New Guinean basins. Favorite insight- 11 events began or ended with annexation and 7 began AND ended with it. Check out maps and conceptual model #river #avulsions @HoosierRiver

The new flume is en route and arriving this week! Labmates will get the first crack at it, but I'm excited to help set things up and take notes!

[St Anthony Falls Lab @saflumn]

Watch SAFL researchers test a new flume, made for UC-Santa Barbara! Stretching 15 meters long, 2 meters wide and 1 meter deep, this flume can recirculate 650 liters per second, reverse flow direction, measure bedload transport and more. Great work on this project, SAFL team!

[Jeff Valenza @ValenzaJeff]

A great team effort from my coauthors @HoosierRiver, @samapriyaroy, and Dr. Hwang! We developed a method to map river avulsions, and found some fascinating relationships between style, channel morphology, slope, and sediment route location.
