| Abstract: | A six thousand year history of streamflow in Mesopotamia is derived from a synthesis of regional paleoenvironmental proxy
data. The proxy data are interpreted with consideration to the climatic signals represented in the records and to the temporal
resolution of the records. A consideration of modern synoptic climatology suggests the spatial patterns of streamflow-generating
precipitation in relation to atmospheric circulation. These patterns provide a framework for the interpretation of streamflow
from the regional proxies. Given the nature of the data at hand, only a low frequency signal is reconstructed. Assessment
of the role of small scale climatic fluctuations as a forcing function of population dynamics must await the availability
of finer resolution environmental data. |
