Geothermal potential mapping of Northeast Morocco (Bekrane-Ahfir) using remote sensing data and GIS

Geothermal energy is part of the renewable mix. It used for heating, air conditioning and sometimes even production electricity. Prospecting such a resource proves to be difficult capital-intensive task. To overcome this constraint, we have remote sensing which an adequate tool guide prospecting through elaboration hydrothermal potential maps at level zones that present favorable exploitation (hyper-tectonized sites, volcanic faulted sites with hot geological formations, seismic zones...). The objective work carry out study on North-East Morocco (Berkane Province), in order identify geothermal as geologically hydrogeologically active sites. methodology adopted consists processing images OLI (Operational Land Imager) TIRS (Thermal Infrared Sensor) sensors Landsat-8 satellite extract spectral indices (Clay mineral Index Ferrous Index,) detecting activity surface temperature map (LST) using muticriteria analysis method (MCA). ) north-eastern Morocco. results obtained show almost perfect concordance distribution above-mentioned indices, lineaments are considered heat drains from depth surface. Moreover, correct correlation was established during validation these inventory springs identified area.
