    CREATING A NATIONAL PARK GEOGRAPHIC INFORMATION SYSTEM: A CASE STUDY FOR THE MOUNT IDA
    (Bulgarian Cartographic Assoc, 2014) Gulgen, F.; Basaraner, M.; Yucel, M. A.; Cetinkaya, S.
    Geographic information systems are essential tools for planning, monitoring, management and sustainable use of resources of national parks. In this study, we present a case study for national park geographic information system for the Mount Ida. For this purpose, topographic maps at 1:25000 scale, GPS-based trekking and climbing routes, campgrounds and other thematic information (flora, fauna, preserved areas, promenade places, forests, biodiversity, campgrounds etc.) and CORINE data obtained from the Turkish National Park Service have been used. Feature and attribute catalogue has been created for the national park with focus on nature-based tourism and outdoor recreation. As a result, national park geographic information system will help carry out national park services efficiently.

    MONITORING METAL POLLUTION LEVELS IN MINE WASTES AROUND A COAL MINE SITE USING GIS
    (Copernicus Gesellschaft Mbh, 2017) Yucel, D. Sanliyuksel; Yucel, M. A.; Ileri, B.
    In this case study, metal pollution levels in mine wastes at a coal mine site in Etili coal mine (Can coal basin, NW Turkey) are evaluated using geographical information system (GIS) tools. Etili coal mine was operated since the 1980s as an open pit. Acid mine drainage is the main environmental problem around the coal mine. The main environmental contamination source is mine wastes stored around the mine site. Mine wastes were dumped over an extensive area along the riverbeds, and are now abandoned. Mine waste samples were homogenously taken at 10 locations within the sampling area of 102.33 ha. The paste pH and electrical conductivity values of mine wastes ranged from 2.87 to 4.17 and 432 to 2430 mu S/cm, respectively. Maximum Al, Fe, Mn, Pb, Zn and Ni concentrations of wastes were measured as 109300, 70600, 309.86, 115.2, 38 and 5.3 mg/kg, respectively. The Al, Fe and Pb concentrations of mine wastes are higher than world surface rock average values. The geochemical analysis results from the study area were presented in the form of maps. The GIS based environmental database will serve as a reference study for our future work.

    Stress accumulation on the Karlıova (Bingöl) Triple Junction after two big earthquakes (Pazarcık-Ekinözü) in Turkey in 2023
    (Ist Nazionale Di Oceanografia E Di Geofisica, 2025) Bektas, O.; Pirti, A.; Alkan, H.; Yucel, M. A.; Buyuksarac, A.
    Active fault zones primarily influence earthquakes in the Karl & imath;ova (Bing & ouml;l) region. The mentioned region is in Turkey's first and second seismic hazard zones; however, it also includes certain areas in the third and fourth seismic hazard zones. In this study, we investigated the earthquake activities using data collected from various global navigation satellite system (GNSS) surveys of continuously operating reference stations in Turkey (CORS-TR). We also analysed the Coulomb stress change caused by the 15 local earthquakes surrounding the Karl & imath;ova Triple Junction. Additionally, we investigated the relationship between Coulomb stress change and horizontal displacements from GNSS survey results, focusing on horizontal displacement vectors. Besides, gravity data were used to infer the fault geometries and shallow crustal structures. The largest horizontal movement was observed at the BIN1 station, the intersection point of the North Anatolian Fault Zone (NAFZ) and the East Anatolian Fault Zone (EAFZ). At the CORS-TR point on the Karl & imath;ova segment of the EAFZ, the horizontal displacement was calculated to be approximately 10.1 cm in the north-eastern direction. The observations of Coulomb stress change reveal that positive stress variations were observed in the NW-SE and SW-NE directions along the main fault line at a depth of approximately 30 km, in accordance with the tilt transformation of gravity anomalies.
