Abstract/Summary

A 1:15,000 scale map of the early Holocene geomorphology of the Great Yarmouth area, covering 33 km2 between National Grid Reference (NGR) 651022, 312244 (northwest corner) and NGR 654523, 303498 (southeast corner) is presented. This was interpolated from elevations for early Holocene deposits derived from 467 borehole records and 539 constraining points extracted from British Geological Survey mapping. The depth to the base of the Holocene sequence ranges from −30.46 mOD to +7.61 mOD. Key morphological features identified include: a 5 km wide trough trending west–east throughout the area; isolated peaks of pre-Holocene sediment reaching to −3 mOD within the centre of this trough and; a series of steep topographical lows. As well as providing a means of assessing palaeomorphology, reconstruction of the region’s early Holocene topography can be used to inform research investigating the available sediment prism, palaeocoastline positions and possible responses to future climate change.
