Research question(s):

How can simple numerical modeling in combination with estimates of paleo-sediment flux and relative sea-level change be used to constrain the role of external forcing on the development of continental margins?

Geometric modeling of the Ebro margin to distinguish allogenic and autogenic responses

Summary of work:

The application of geometric modeling to shelf-margin stratigraphy has the potential to constrain interpretations of external forcings on margin development. Such a model was applied to the Ebro margin in order to complement the analysis of Kertznus and Kneller (2009). The results suggested that increased mass wasting in the Pleistocene was unlikely to have been a factor in the observed long-term shelf-edge trajectory, and that the trajectory can be explained by the interaction of sediment flux, relative sea-level rise, and basin shape.
