Definition of Foreshore / Beach face:
The zone between MLW and the seaward berm, which is equivalent to the upper limit of wave uprush at high tide (the latter is identical to the seaward beach berm). For practical reasons the administrative upper delineation of the foreshore/beachface is defined as the intersection between the MHW line and the coastal profile, which is identical to the definition of the shoreline[1].
This is the common definition for Foreshore / Beach face, other definitions can be discussed in the article

Notes
[1]The foreshore can be said to be the part of the shore/beach, which is wet due to the varying tide and wave run-up under normal conditions, i.e., excluding the impact of extreme storm waves and storm surge. This means that the foreshore in morphological terms extends further up on the beach than the intersection between the MHW and the coastal profile (MHW line). However, for practical reasons the administrative upper delineation of the foreshore/beachface is defined as the intersection between the MHW line and the coastal profile, which is identical to the definition of the shoreline.
The shoreline may include 'soft' mobile or semi-mobile sediments (sand, mud and shingle), or 'hard' rocky shorelines (composed of resistant material).
