The erosion file contains the amounts of each pool removed from the site due to erosion events. Each eroded pool amount can be reduced by the fractions specified in the site parameters category Erosion and Deposition. Erosion files are optional. Your management can have erosion events without writing an erosion file. Specify the name and path of the erosion file in the Management Editor's "Simulation Information" dialog page.
This file can be used as input for deposition events. Specify the deposition input file and path in the Management Editor's "Simulation Information" dialog page.
The erosion file is written in netCDF format. You can use the utility ef2csv to convert the file to a text, CSV format which can be imported directly in your spreadsheet software.
