damn optical illusion... scratch that then ... like the drainage pipe idea is good but over time the material on top get filled with fines and organics and seals it and the pipe get ether squish or gets filled and it need to be redone and its going to cost you a bunch in material and time where if this ditch get filled with sand you can just scoop it out ... This situation can be fix with the proper material and grade ... I don't like these big rock I would've suggests some material that provide compaction so water can flow uniformly on it without washing out ...So under the sand is washed screenings that was graded to drain with a 1% slope. I believe they did a 50/50. So the middle being the high point. Under that washed screenings is a permeable fabric to prevent any vegetation growth from the fill we had to bring in to build up this section of field (I will look for a picture of the field when hit with a lot of rain). I will also try to get a better picture, but the red circled area isn't lower than the blue area, it only looks that way in the photo.
My other thought was to try putting some pea gravel to fill in the gaps around the surge rocks and hopefully that would work as a filter. I was going to buy a couple of bags and try it out in one spot. The sand loss isn't huge, its the filling the ditches in those spots that is the problem. I need the water to drain out of the ditch.
Maybe move the rocks towards the ditch a bit and back up the sand and put some pure stone .75 to .15 in between the two hand have the rocks higher then the sand grade hopefully this should hold the sand in ... that should hold your sand in place...
