EUROSEM was developed by team of scientists funded by the European Union during the late 1980s and early 1990s. The project developed a truly dynamic and distributed soil erosion model for use in field and small catchments for single events. The model reflected the state-of-art at the time and is still one of the most physical realistic simulations of soil erosion available.
The model can be downloaded from the downloads page. The model's code has also been made available. The code is written in Fortran and has a number of authors, most notably Roger Smith and John Quinton, so if you do use it please credit us. However, there are no guarentees that it works and I am afraid no support is available - so user beware! If you do use it and can share the results, let me (John Quinton) know and I'll post a link to your work.
The key paper on the model is:
Morgan, R.P.C., Quinton, J.N., Smith, R.E., Govers, G., Poesen, J.W.A., Auerswald, K., Chisci, G., Torri, D. and Styczen, M.E. 1998. The European Soil Erosion Model (EUROSEM): A dynamic approach for predicting sediment transport from fields and small catchments. Earth Surface Processes and Landforms, 23: 527-544. PDF
The model's user guide is available on the download page and you can download a EUOSEM bibliography here.
