Autogenic and allogenic forcing interacts at different timescales, and their interaction results in the sequential sedimentary patterns observed in fluvial sediment records (Abels et al., 2013). Field studies help to understand surface processes in the past and interpret the way fluvial architecture is formed. That is crucial for geological modeling of subsurface basin fill. However, it is not easy to differentiate autogenic forcing from allogenic, because of their overlapping temporal and spatial scales and the influence of allogenic factors on autogenic ones (Bridge, 2003; Stouthamer & Berendsen, 2007). In my project, I study this interaction by using numerical forward modeling tied to field data. In 2017, using a Molengraaff grant, I have been able to document high-detail excellent fluvial outcrops in the Bighorn Basin, Wyoming, using drone- based photogrammetry. Based on these data and combined numerical modelling work, I would like to report my progress in the last year.
