“…In general, the formation of karst depressions is the result of complex interactions between strong dissolution, hydrodynamic processes, and geomorphologic evolution. Influencing factors include the geological setting (e.g., lithology, tectonic movements, neotectonic activity), hydrological conditions (e.g., hydrological evolution), geomorphology (e.g., elevation, slope), climate (e.g., interglacial, ice age) and other factors (e.g., vegetation, soil cover, human activities) related to karst depression development (Al-Kouri et al, 2013;Panno et al, 2013;Cahalan et al, 2018). Each factor has different fluctuations in time and space, and it is difficult to decipher the degree of influence of each factor on karst depression formation by direct observation or quantification.…”
