On rivers and lakes I would also use the water boundary as border for the beach.

Where is it difficult? An example would help?

As a counter example;

Here is Bondi Beach, Australia. https://www.openstreetmap.org/edit#map=17/-33.89168/151.27720

If you use the LPI Imagery you can clearly see the sand under the water edge.

If you use the Bing, Digital Globe, ERSI, Mapbox, AGRI imagery you can see towards the low water mark.
