Mapping late holocene landscape evolution and human impact - A case study from lower khuzestan (SW Iran)

Recent advances in the fields of remote sensing and GIS provide the techniques to establish a firm geomorphological framework to the historical and archaeological studies in the Mesopotamian region. This study presents a practical approach for the mapping of the semi-arid, alluvial landscapes of Lower Khuzestan. As elsewhere in Mesopotamia, the landscapes here are strongly affected by anthropogenic processes, most evidently expressed by widespread irrigation patterns. The image interpretation key and map legend are therefore designed explicitly to reflect these typical alluvial and human-induced landforms. The working procedure is based on easily accessible and inexpensive source material, notably Landsat and CORONA imagery, SRTM elevation data and readily available topographical maps, and was successfully applied in a case study on the evolution of the Jarrahi River. The resulting map, together with information from other disciplines, provided insights into the complex landscape evolution of the study area and a useful base for further research.
