Applied Sedimentology Sedimentary rocks cover about 75% of the earth’s surface and host the most important oil and water resources in the world. Sedimentological research and teaching at the Darmstadt University of Technology focus on applied aspects with specific emphasis on hydrogeological, engineering and environmental issues. However, also research related to oil exploration is carried out with a speciality in palynology and reservoir characterization. To predict groundwater movement, pollutant transport or foundations of buildings in sedimentary rocks a detailed knowledge about the hydraulic, geochemical or geotechnical properties is needed which often vary about several magnitudes. This kind of subsurface heterogeneity can be related to distinct sedimentological patterns of various depositional systems. In addition, changes of depositional systems with time can be explained by specific controlling parameters e.g. changes in sea level, climate, sediment supply and are nowadays described by the concept of sequence stratigraphy. The research in applied sedimentology also includes modelling of erosion and sediment transport and its implication for the management of rivers and reservoirs with the help of GIS. In 2002, a georadar equipment has been established as a specific method for nearsurface investigations. First results in the exploration of soils, rocks, and river dikes could be achieved on various test sites in SW Germany. In the meantime, a centre of near surface investigation methods has been founded by the Universities of Frankfurt (Applied geophysics), Tuebingen (Applied sedimentology), Gießen (soil sciences), industrial partners and the TU Darmstadt. Within this Center an instrumental pool is shared, regular meetings are organised and research projects are initiated. In 2005, self-constructed facilities for permeability measurements of soil and rock materials in the laboratory went into operation. In 2006, two new DFG projects have been started in the sedimentological research group. One is part of a DFG-Forschergruppe together with the Universities of Frankfurt, Mainz and others. This joint research group investigates the origin and evolution of extreme rift-flank uplift in East Africa and its impact on climate, environment and the human evolution (see special contribution). The other concerns the reconstruction of Miocene plate reorganisation in western Mexico by interpretation of syntectonic volcaniclastic successions of the Transmexican Volcanic belt.
