This entire technical guide is designed to offer archaeologists the required history wisdom in environmental technology required to excavate and research archaeological websites through rivers and on floodplains. Bringing jointly details at the evolution and exploitation of floodplain and river landscapes, this article attracts on examples from Britain, Europe, North the United States and Australasia. a tremendous topic is the interplay among climatic and cultural forces and the transformation of riverine environments.

Intro. 5 The climate-culture chain of the Nile valley. PART I PRINCIPLES FLOODPLAIN EVOLUTION Floodplains are one of the most conspicuous and widespread of all the landforms on the earth. They are the result of both erosional and depositional processes. Over time they develop and change and so they evolve, not to any end-point but to the form that they are today or were at any point in the past. e. geology) and has much in common with scientific archaeology in both its history and methodology. An understanding of the fundamental processes and products of floodplain evolution is essential for the interpretation of sites in alluvial contexts and can yield fascinating insights into human-environment relationships.

Both of these factors are liable to change, the former because of channel and floodplain aggradation, the latter because of climatic change, and/or hydrological change caused by humans. It is fairly straightforward to estimate the areas inundated by floods of different magnitudes (see appendix 3), as is done for floodplain zonation planning and insurance risk assessment. e. assuming only bed aggradation and not equilibrium floodplain aggradation) which will alter the spill volumes of lower magnitude floods, which would in turn affect the flood series.

Adapted from Bulletin of the Geological Society of America, by permission of the Geological Society of America. ical change of New South Wales coastal rivers is caused by alternating periods of flood-dominated and drought-dominated regimes. These studies illustrate the danger in regarding short-term climatic change as minor in comparison to astronomically forced climatic changes which produce glacial/interglacial cycles (Milankovitch forcing).
