Existing aeolian transport formulae tend to overestimate the sediment transport volumes in coastal environments. Supply limiting factors like moisture content, shell patches, sediment sorting, vegetation and morphological features are believed to explain these overestimations. These supply limitations act on a variety of spatio-temporal scales that hinder relating supply and transport. Probabilistic graphical models (PGM) can be used to cope with the variety and complexity of these relations. A long term measurement campaign is started to feed such probabilistic models with data on the complex interaction between supply limitations and their influence on coastal aeolian transport and subsequently dune growth. The variety of spatio-temporal scales involved in supply limited coastal aeolian transport generally is not fully captured by traditional measurement techniques. This campaign uses, apart from traditional in-situ techniques, remote sensing and image analysis techniques to cover a variety of spatio-temporal scales that are related to coastal aeolian transport and supply limitations in particular. We aim to construct a dataset that contains long term and high resolution grid data as well as binary time series and a variety of in-situ measurements on (local) wind forcing, beach surface properties and aeolian transport. The probabilistic graphical models will be used to consolidate the dataset towards practical instruments to model the large scale and long term (LSLT) behavior we are finally interested in.
