Paleoreconstruction of past coastlines - what role for topography?

Paleoreconstructions are a useful tool to better understand past, present and future responses to environmental change due to geological and geomorphological processes. This paper presents a reconstruction of the coastlines of the Gulf of Trieste at the transition from the Pleistocene to the Holocene, around ten thousand years ago, when the sea began to flood the area of the present-day Gulf. Although today's topography is the most commonly used input for modelling past coastlines, the results of this study show that reconstructions are much more reliable when the past topography of the study area is used in the modelling. Furthermore, the results of this study support previous hypotheses that the sea inundated large parts of the present-day area of the Gulf of Trieste relatively quickly in the early Holocene.
