Monica asks: “Hi! in your experience…do u know any example of sediment waves on levees founded or described in outcrop?
thanks.”

Great question. My intutition is that some of the interpreted levee successions in outcrop do contain sediment waves. The issue is definitively recognizing them … a big problem is that these features are extremely subtle (100s to 1000s meters in wavelength and only several meters in amplitude). They are so apparent on bathymetric maps and seismic-reflection profiles because of vertical exaggeration. So, you would need a very big outcrop (at least a couple km) with the thin-bedded levee facies exposed perfectly (which is tough to find).

Off the top of my head, I can’t think of a paper/study that specifically discusses sediment waves in outcrop … I could do a bit of digging around if you’re still interested.
