Management of beached particles.

Hi!!

I have been taking a look on plasticparcels in order to use it to perform a series of simulations. The thing is that my study case has a different approach to the examples you have uploaded to the documentation page. The main objective in this case is to study the deposition of plastic debris along the coastline of a certain region. These debris are emitted from the Ulla river, being the only source point.

What I have encountered by looking at plasticparcels documentation, is that there is not really any kernel/function that can differentiate beached particles from non-beached ones. I am guessing that particles just get slower and slower until they reach a certain velocity threshold, which "marks" them as beached, even though they technically are not.

I have seen that you have an "unbeaching" kernel that puts particles back in motion in case they reach a very low velocity. But I was wondering if there is some way of actually differentiate between beached and non-beached particles.

Also, with my previous software, I was able to introduce a shapefile which represented the study area coastline, divided into a series of segments (polygons), and then post process my result files in order to get the particle distribution along the coastline (registering the arrival of new particles during the study period).

I asked a similar question a few months ago, but I was then working with Parcels v3.0. I'm guessing there might not be significative differences, but maybe there are some new features on the way, which might include something like what I have mentioned?

Cheers!!
