Palaeohydrology and its impact on groundwater in arid environments: Gebel Duwi and its vicinities, Eastern Desert, Egypt doi Spatial

From ancient times, access to water in arid and hyper-arid regions has been crucial for life. Increased knowledge about groundwater conditions is therefore extremely important for the future development of desert areas. Gebel Duwi, a limestone ridge, sited in the today hyper-arid Eastern Desert of Egypt, was chosen for testing current hypotheses concerning the interdependence of palaeohydrologic features and geologic settings for groundwater investigations. Two sub-basins are identified in affecting Gebel...

Analyzing two-dimensional effects in central loop transient electromagnetic sounding data using a semi-synthetic tipper approach doi

We present a simple and feasible approach to analyze and identify two dimensional (2D) effects in central loop transient electromagnetic (TEM) sounding data and the correspondingly derived quasi 2D conductivity models. The proposed strategy is particularly useful to minimize interpretation errors. It is based on the calculation of a semi-synthetic TEM-tipper at each sounding and for each observational transient time point. The semi-synthetic TEM-tipper is derived from the measured vertical component of the...

PaleoMaps: GIS based Palaeoenvironmental data collection for the Last Interglacial (125ka) of Egypt SFB806 doi Spatial PaleoMaps

The growing number of paleoenvironmental data, GIS-based analyses and modelling allows us to produce PaleoMaps for a given area. However, the „translation“ of paleoenvironmental information in maps is even more complex, than producing maps as an illustration of the present. The CRC 806 “Our Way to Europe” provides the background to study the culture-environment interaction and human mobility in the Late Quaternary. Northeastern Africa during the Last Interglacial is thereby an important region and timespan....

Investigation of the Azraq sedimentary basin, Jordan using integrated geoelectrical and electromagnetic techniques doi

The Eastern Mediterranean has been used as a passageway for human migration from Africa to the Middle East, the Balkans and Europe. The Azraq basin in the eastern desert of Jordan has been a major spot for human settlements since the middle Pleistocene. The former lake in the basin centre has developed to a hyper-saline alluvial mudflat, the Qa’ Al Azraq. In the mudflat thick sequences of alluvial sediments are deposited. Such sediment successions are promising archives used for reconstructing a...

Geoarchaeological site documentation and analysis of 3D data derived by terrestrial laser scanning doi

Terrestrial laser scanning was conducted to document and analyse sites of geoarchaeological interest in Jordan, Egypt and Spain. In those cases, the terrestrial laser scanner LMS-Z420i from Riegl was used in combination with an accurate RTK-GPS for georeferencing of the point clouds. Additionally, local surveying networks were integrated by established transformations and used for indirect registration purposes. All data were integrated in a workflow that involves different software and according results....

Mehrskalige geomorphometrische Analyse des Gebel Duwi, Ägyptische Ostwüste (diploma thesis University of Cologne) Spatial

This geography diploma thesis was written by Harriet Berkhan within the framework of the CRC 806 “Our Way to Europe: Culture-Environment Interaction and Human Mobility in the Late Quaternary” at the University of Cologne. The thesis looks into the working hypothesis, as to whether the current morphology can yield important evidence for the discussion about the “Out of Africa” dispersal of anatomically modern humans (AMH) and the reconstruction of the palaeoenvironment. Inasmuch as there are no large-scale...
