Reed Goodman University of Pennsylvania Liviu Giosan Woods Hole Oceanographic Institution THE TIGRISEUPHRATES DELTAIC COMPLEX AND ITS RELATION TO THE LAGASH FLOODPLAIN Settlement in Mesopotamia was determined by the size and distribution of its river channels, most notably the Tigris and Euphrates. But the delta(s) these rivers built, and the unique ecological setting that followed, resulted from an interplay between coastal (sea level) and fluvial (river) processes. This dynamic exchange supplied the necessities of life, and their location: from the basics of land and water to the more unknowable but no less significant specifics of nutrient fluxes and biota. To understand what this landscape looked like at critical points in history, we need to model the formation and evolution of the entire TigrisEuphrates deltaic complex. We also need to define delta type. Beginning with the worldwide initiation of deltas brought on by a deceleration in sealevel rise, Iraqs southern
