GENERAL

It has been difficult to strike a balance in a book of this kind between discussions of the ways the data have been processed and analysed on the one hand and substantive questions about history and archaeology on the other. Ultimately we have favoured an approach in which we keep the former to a minimum in the main text, but instead make use of this appendix to lay out some methodological issues in greater detail. Even so, we continue trying to keep the use of equations and other symbolic notation to a minimum in the discussion that follows in the knowledge that those who wish for a full and formal treatment can and should follow up the referenced sources. The following sections are structured by the order in which various techniques arise in the main text.

CHAPTER 3

Erosion Models

In Plates 2a—b (as well as a follow-up in Plates 3la—b), we consider two kinds of meso-scale erosion model: RUSLE3D and USPED. Our input parameters for these models are provided in Table 3.1 and we do not think there is much further information that we can add here. For the general methods, please see Mitasova et al. 1996; Mitasova and Mitas 2001, and for a more detailed discussion of the Antikytheran example in relation to terracing, see Bevan and Conolly 2011.
