Wetlands constitute rich biodiversity reserves and hotspots associated with extensive ecosystem functions globally. Wetlands in the Mediterranean transect of Turkey, which are greatly referred to international significance and conservation concerns, are unfortunately under intensifying threats because of the gradually (sometimes quite rapidly) changing hydro-climatic conditions and mostly the emergence of droughts. This fact requires the use of scientific approaches in these areas to guide protective/restorative policy actions and to orient engineering solutions. Yet, such efforts will certainly require solid records of river discharge data that can sufficiently represent inlet hydrologic conditions to the wetlands of interest, while it is observed that either no hydrographic station is available or the data series lacks either the required quality or the length. Based on this knowledge and understanding, the methodology that is partly exemplified in the present study provides an analytical framework tailored towards the use of hydro-meteorological drought indices in assessing wetland sustainability. The study on the use of drought indices in a novel handling for the annual series of maximum drought severities is an extension of the approach that was previously suggested by Onuşluel Gül et al. (2022) and Kuzucu and Onuşluel Gül (2023). The results on targeted assessments for detecting trends in significant drought characteristics are presented over a series of spatially distributed wetland systems that distinctively represent Mediterranean hydrologic conditions.
