INVESTIGATION OF THE UNDERGROUND BUILDING HERITAGE AND THE MECHANISM OF WATER FLOWING IN QANĀTS IN PALERMO THROUGH INNOVATIVE SURVEYING TECHNIQUES

This study investigates the impact of floods on the aquatic ecosystem by means of freshwater mussels instrumented with sensors to monitor the opening of their valves. Signal analysis techniques were used to gain insights into their responses in terms of changes in the intensity and frequency of valve gaping. The approach used in the study potentially enables the development of real-time monitoring systems for ecological purposes, offering a pathway for practical biological early-warning systems.
