The Development and Characteristics of Ancient Harbours—Applying the PADM Chart to the Case Studies of Ostia and Portus
Fig 5
Harbour operation and PADM of the core PO-2.
PADM chart based upon core PO-2 that represents how the harbour basin of Ostia may have been used. The chart incorporates stratigraphic data as well as factoring in the dredging level hypothesis and possible ship draughts. The PADM shows different stages of harbour potential through time and proposes different hypotheses relating to levels of dredging.
