Hello GIS folks,

Recently I am doing a small project on calculation shoreline movement using the DSAS v5.0 by USGS on ArcMap 10.8.2 for a 10 year period. Everything is set perfectly, the plugin ran well and returns a seemingly good result. But after revise it througoughly, I think it might cause an error as produce contrasting results on a group of transects on a same set of baseline and shoreline, i.e. the green (for (+) result/accumulation) and red (for (-) result/erosion) on a patch of mangrove which should be accumulation together (see attached image).

Has anyone of you guys ever faced this problem and what are the possible solution for it?

Thank you in advance!
