from Part IV - Human settlement, climate change, hydrology and water management

ABSTRACT
Wadi Faynan, southern Jordan, provides an archaeological record of human settlement from the Lower Palaeolithic to the Islamic period, and indeed into the present day. As for any long-term record of settlement, an understanding of the changes in economy and society requires knowledge about the impacts of climate and environment change on human communities, especially when dealing with settlement in arid landscapes. This chapter attempts to place the 10,000 years of Holocene settlement in Wadi Faynan between c. 12,000 and 2,000 years ago into its hydrological context. A rainfall-runoff model is used to examine the potential impacts of both Holocene climatic change and human behaviour on the hydrological behaviour of the wadi and then on human settlement. Wade et al. (this volume, Chapter 12) have shown that rainfall-runoff models can successfully simulate the behaviour of the present-day wadi system, demonstrating how such behaviour is sensitive to variability in rainfall and infiltration rates. Here we use the results of regional climate modelling to determine statistical properties of palaeo-rainfall for the Wadi Faynan and then use a stochastic weather generator (this volume, Chapter 5) to create a rainfall series which is used to drive the hydrological model. Results are used to explore the potential impacts of climatic variability on human communities from 12,000 to 2,000 years ago, demonstrating that palaeohydrology may provide a bridge between regional-scale climate data and local-scale cultural developments.
