Multidimensional Analysis of Potential Cost-to-Cost Risks of Climate Disruption for Energy-Focused Facilities Using Remote Sensing, Drone Photogrammetry, and GIS Methods

One of the changing world climate disorders generally caused by human beings in the long term is abnormal precipitation or droughts. Abnormal rainfalls or droughts experienced in almost every season in Turkey and in the world continue to take a high share of this situation in power plants operating in the energy sector. One of the regions in Turkey affected by the sudden decrease and sudden suppression of rainfall in recent years is the Eastern Anatolia Region. This study was carried out to investigate possible environmental risk factors in a series of HEPP areas built side by side within the borders of Erzincan and Erzurum Provinces. In these power plants, uncontrolled floods caused by excessive rainfall, potential damage to structures such as transmission channels, pools and weirs, or malfunctions in main sections such as main buildings and regulators will be directly affected. Although these structures are built to withstand natural disasters such as earthquakes and excessive rainfall, it may not be foreseeable that climate disturbances will not pose a greater risk. This study was carried out using Geographic Information Systems (GIS)-based Multi-Criteria Decision Analysis (MCDA) by taking into account environmental risk factors such as precipitation risks and landslides that have affected in recent years by evaluating them together with land use. A digital terrain model and orthophoto images were created using drone photogrammetry over the approximately 15 km length and 50 meters wide area where the two power plants are located. An attempt was made to create a risk model with the parameters of land use, elevation, slope, aspect, precipitation, temperature and distance to the streams.
