Abstract

This paper evaluates the effectiveness of restoring open‐water area in a wetland via a geographical framework that goes from a general perspective to a detailed view. The methodology relies on diachronic cartography, remote sensing through Landsat satellite imagery validated by in situ hydrological data (2000–2022), and details from field work. We analyzed the water surface area of Comana freshwater marsh in Southern Romania. The water surface area recorded a statistical change point synchronous to the restoration actions. The water surface area increased due to restoration actions in 2011 and then became relatively stable. Post‐restoration, the mean monthly discharge of Neajlov River correlates statistically with the water surface area. The water has low depths in the marsh; yet, the area covered by vegetation appears to be stable. The persistence of the effects for over a decade recommends Comana Marsh as a demonstrative case study in South‐Eastern Europe and for further monitoring activities.
