    Reburial of mosaics: Field experiment comparing six different systems based on the results of monitoring station in Perge
    (Bursa Uludağ Üniversitesi, 2021-09-12) Yeşil, Şehrigül
    The effectiveness of six different reburial systems was investigated by means of a monitoring station installed on a part of approximately 110 square meters of mosaic, defined as basilica thermarum in the Southern Baths of the ancient city of Perge. The scope of the study covers the monitoring of six different reburial systems consisting of only soil filling on the tessellatum layer; only sand filling on the tessellatum layer; sand filling on geotextile laid on the tessellatum surface; sand and gravel, respectively on geotextile laid on the tessellatum surface; geotextile and pozzolana on the tessellatum surface, and finally, approximately 5 cm sand, geotextile, and 15 cm sand on the tessellatum surface. Key parameters, which lead to deterioration such as moisture content in these systems, system response to the precipitation, temperature change, acidity, salt content, and plant formation were evaluated comparatively. In these systems, Decagon 10HS soil moisture sensor for moisture measurements and Apogee ST100 soil temperature sensor for temperature measurements were employed. Atmospheric humidity, atmospheric temperature and precipitation data were collected with a Davis® Vantage Vue™ Wireless Weather Station set. Data of salt content, acidity and elemental composition were obtained through conductivity analysis, pH tests, X-ray fluorescence (PED-XRF) analysis. Having reached under the reburial system, species analysis of plants that cause mosaic deterioration was realized, and the coverage degree of those plants was determined according to the Braun-Blanquet cover-abundance scale. This research, in which data for the years 2017- 2018 were evaluated, showed that each monitored reburial system had certain advantages and disadvantages according to the above-mentioned parameters.
