Help me solve my drainage/mud problem

I have a consistent issue when we get significant rain where the culvert under my driveway gets clogged/blocked with mud and the water diverts over my driveway. I dig it out everytime but the issues is getting worse and i'm hoping for a permanent solution.

Here is a picture of the drainage ditch. I'm standing on my driveway.


I dug a little of the very soft mud to show the top of the culvert at the bottom of the picture.


Up hill and where a lot of the water is coming from, the drainage ditch is minimal at best. Here are a few pictures.


In the distance of this picture, the wheelbarrow is sitting on my driveway.


Now, the good news is that the previous 2 pictures are taken in front of where my parents are building their house (right next door) and if the solution involves correcting something in front of their house, that will be no issue.

I guess the water is pulling dirt from in front of their house and draining down to my ditch and clogging the culvert? How can i fix that? Would gravel, larger rocks or rip rap there help any?

Any tips appreciated.
