rip channels at the times shown in column 1 above. 

The folder 'All MInima' contains along and cross-shore locations of all minima found with 
the computer algorithms after being sorted into rip channels. Each column corresponds to 
a seperate rip channel. Note that there are folders '1999, 2000, 2001 and 2002'. 
Inside each folder is another folderlabelled 'relic', this contains the alongshore locations
of rip channels that were manually digitised to fill in the data set. The relic rip 
information was for rip channels that did not fit the required rip channel definition.
