Groundwater Exploration in Western Saudi Arabia Using Landsat-TM Imagery@@@استكشاف المياه الجوفية في غرب المملكة العربية السعودية ، بإستخدم صور لاندسات - TM

Structural lineament analysis of Landsat Thematic Mapper data was utilized to study the groundwater potentiality and recharge in the central part of the arid Arabian Shield. Fracture line-to-line inter- section was found to be a good indicator for groundwater occurrence and recharge; the connectivity of intersected fractures may indicate potential areas for water occurrence. Because Makkah, Jeddah and Taif lie within the study area, results will benefit the groundwater ex- ploration for these cities.
