Abstract  The paper summarizes the different modes of failure affecting earth dams as a consequence of earthquake shaking. A case study is presented to illustrate seismic deformation analysis using the Alibey Earth Dam, Istanbul, Turkey as an example. The dynamic behaviour, failure modes and mechanisms of failure of the dam under possible ground motions were investigated. The results from finite element analysis are compared with the experimental study. [ABSTRACT FROM AUTHOR]

Abstract  Each day some 400–450 ton solid waste is dumped on land and in the sea and rivers in the coastal cities of the eastern Black Sea, creating serious environmental problems. The paper reports the engineering geological studies of a proposed landfill site for Trabzon, a major city in the region. Fieldwork included scan-line and seismic surveys as well as boreholes and in-situ testing. Water absorption tests indicated permeabilities in the order of 10−8 m/s. [ABSTRACT FROM AUTHOR]

Abstract  A case study for the use of an artificial neural network (ANN) model for landslide susceptibility mapping in Koyulhisar (Sivas-Turkey) is presented. Digital elevation model (DEM) was first constructed using ArcGIS software. Relevant parameter maps were created, including geology, faults, drainage system, topographical elevation, slope angle, slope aspect, topographic wetness index, stream power index, normalized difference vegetation index and distance from roads. Finally, a landslide susceptibility map was constructed using the neural networks. The drawbacks of the method are discussed but as the validation procedures used confirmed the quality of the map produced, it is recommended the use of ANN may be helpful for planners and engineers in the initial assessment of landslide susceptibility.
