Today, urban centers are facing increased challenges and contemporary urban problems, the most important of which is the rapid urban growth imposed by the huge rise in the population. Therefore, today there is a scarcity of surface areas along with the high demands for facilities and general services by residents. Therefore, the use of underground spaces in city centers is one of the best alternative solutions to meet these increasing demands while preserving the overall structure of cities and avoiding damage to the natural and environmental resources, with emphasizing that underground solutions for city centers should be taken into account in the early stages of planning and developing cities in order to make them more successful and effective. Hence, this paper will highlight the most prominent problems experienced by highly populated urban cities and how to find solutions to these problems through the optimal use of underground spaces.
