The Zohreh Prehistoric Project (ZPP), a long-term archaeological research
programme focused on the river valley south of the modern city of Behbahan
in Khuzestan Province, was launched in April 2015 (Figure 1). The valley,
which lies in close proximity to the northern coast of the Persian Gulf, was
surveyed extensively during the early 1970s by Hans Nissen from the Oriental
Institute of the University of Chicago (Nissen & Redman 1971; Dittmann
1984, 1986). The ZPP aims to develop full-coverage archaeological survey of
the valley, focusing on the human landscape over time, mostly in relation to
settlement hierarchy and dynamics, modes of production and the emergence of
regional centres at the end of the fifth and beginning of the fourth
millennia BC. The focal point for the project is the principal site of the
Zohreh Valley, known as Tol-e Chega Sofla (39RN1Q22108; the
site was previously registered as Chogha Sofla, BZ.71 (Dittmann 1984: 110).
We have changed this to reflect its local name. The digital reference is the
unique Iranian archaeology map registration number.
