Sedimentological and computer-based investigations on fluvial dynamics within the Ethiopian Highlands

svenja_meyer_blog_ethopia Ethiopia constitutes several unique research sites for understanding human response to environmental change during the Late Quaternary. Diverse environments were created by interacting tectonic and climate regimes and discovery of numerous archaeological records give reason for geoarchaeological research on caves, rockshelters, and surrounding landscapes. Mochena Borago Rockshelter is under study for Late Pleistocene to Holocene occupation of anatomically modern humans and builds the chronological framework for integration of Later Stone Age (LSA) and Middle Stone Age (MSA) assemblages within the southwestern Ethiopian Highlands. 10 km east of Mochena Borago, areas affected by gully erosion at Bisare River site have exposed obsidian raw material outcrops and archaeological (LSA, MSA) assemblages.

Sedimentological and GIS-based drainage system and geomorphological analyses are conducted to understand actual and ancient fluvial dynamics and archaeological preservation within the catchment of Bisare River in order to reconstruct ancient landscapes. Together with Mochena Borago and Bisare River in the southwestern Ethiopian Highlands, investigations at site Dendi Lake in the central Ethiopian Highlands on archaeological assemblages of all Stone Age periods are carried out. Therefore, the Dendi caldera complex is under study for GIS-based and sedimentological geomorphological mapping and hydrological analyses of the lake in- and outflow for paleoenvironmental reconstruction.

Water resources assessment in arid data-scarce regions – multidisciplinary research in Egypt


Dr. Mohamed Youssif

Arid regions are highly vulnerable with respect to environmental and particularly hydrological changes. Data scarcity for most of these areas (such as Egypt and the most of Middle East) is a great challenge for hydrogeological investigation at practical scales. Moreover, climate change will exacerbate groundwater-related problems by reduction in recharge rates in some areas, increased reliance on groundwater resources due to decrease in the reliability of surface-water sources, saltwater intrusion due to sea-level rise, and deterioration of groundwater quality by increased flushing of urban and agricultural wastes.
