17 p, 2.2 MB Carbon and oxygen isotopic composition of the Middle Miocene Badenian gypsum-associated limestones of West Ukraine / Peryt, T.M. (Polish Geological Institute, National Research Institute) ; Durakiewicz, T. (Los Alamos National Laboratory) ; Peryt, D. (Polish Academy of Sciences. Institute of Paleobiology) ; Poberezhskyy, A. (National Academy of Sciences of Ukraine. Institute of Geology and Geochemistry of Combustible Minerals)
The middle Miocene Badenian basin of the Carpathian Foredeep is characterized by complex sedimentary and diagenetic carbonate-evaporite transitions. Six locations have been selected to evaluate the controls on the carbon and oxygen isotopic composition of the Badenian gypsum-associated limestones of the Tyras Formation in West Ukraine. [...]

14 p, 1006.3 KB Groundwater characterization of a heterogeneous granitic rock massif for shallow tunneling / Font-Capó, J. (Universitat Politècnica de Catalunya. Departament d'Enginyeria Geotècnica i Geociències) ; Vazquez-Suñé, E. (Consejo Superior de Investigaciones Científicas. Institute of Environmental Assessment and Water Research) ; Carrera, J. (Consejo Superior de Investigaciones Científicas. Institute of Environmental Assessment and Water Research) ; Herms, I. (GEOCAT, Gestió de Projectes, S.A.)
Shallow tunneling may encounter a number of problems, the most important of which is high water inflows in transmissive areas that are often associated with fractures or discontinuities. Moreover, research into shallow tunneling may be limited by the duration and cost of the civil engineering works. [...]

12 p, 1.1 MB Overwash hazard assessment / Rodrigues, B.A. (Universidade do Algarve) ; Matias, A. (Universidade do Algarve) ; Ferreira, Ó. (Universidade do Algarve)
Overwash is a natural storm-related process that occurs when wave runup overcomes the dune crest. Because coastlines are globally occupied, overwash is a hazardous process and there is a need to identify vulnerable areas. [...]
