IntroductionSedBerg has been developed to simulate sedimentation in high-latitude glaciated fjords. The model simulates the formation, drift, and melt of a population of icebergs utilizing Monte Carlo based techniques with a number of underlying parametric probability distributions to describe the stochastic behavior of iceberg formation and dynamics. This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License, version 2, as published by the Free Software Foundation. HistoryThis model was developed by Ruth Mugford during her PhD work at Scott Polar Research Institute, University of Cambridge from 2004-2008. It is supplied "as is", so it may require some tweeking to get it running on your system. Feel free to contact Ruth if you are planning on using the model it as she is still working on it.
