    Monitoring landslides with geophysical and geodetic observations
    (Springer, 2015) Zeybek, Mustafa; Sanlioglu, Ismail; Ozdemir, Adnan
    The objective of this study was to evaluate and predict land movement by integrating geodetic, geophysical and meteorological data in a landslide area. Specifically, electrical resistivity tomography surveying, Global Navigation Satellite System and terrestrial laser scanning techniques were integrated to monitor a landslide. The study area lies to the southeast of the town of Ta kent in southern Turkey, close to Balcflar in the Central Taurus mountain chain. Landslides result in considerable damage to structures, farmland and the environment in this area; therefore, it is important to characterise the size, extent and timing of past land movements in order to mitigate damage from future landslides. Analysis presented in this paper shows that the greatest land movements in the region occur in spring, when average motions can be up to 1.5 m per month. It is demonstrated that integrated techniques provide a better means for monitoring landslide processes and gathering data for predictions of future movements. Mapping landslide movements by integrating geophysical and geodetic observations can provide a meaningful evaluation of a landslide and its dynamics.

    PHOTOGRAMMETRIC SURVEY AND 3D MODELING OF IVRIZ ROCK RELIEF IN LATE HITTITE ERA
    (Univ Agean, Dept Mediterranean Stud, 2013) Sanlioglu, Ismail; Zeybek, Mustafa; Karauguz, Gungor
    In this study, the photogrammetric measurement technique was used to document the Ivriz relief, which is located under the Kocaburun Rock on Mount Aydos in the village of Ivriz (Aydinkent), Konya-Eregli. This relief has been standing since B.C. 720 but suffers from man and environmental agents. It has been standing high from ground on rock facade. Therefore a 3D (three-dimensional) model of the monument was obtained as a result of the work conducted for protection. Conservation has been done by close-range photogrammetry technique. Using close-range photogrammetry, in which only some brief field work was done with a majority of the other work being conducted in an office, documentation can be efficiently performed using free equipment and software as well as scaled archives to produce three-dimensional models of historical and cultural heritages in a digital environment.
