Lake Zóñar level modeling under different scenarios, including various degrees of spring diversion (a), natural climate aridification (b) and a combination of anthropic and natural climate causes (c). The lake level is forced to decrease to the threshold of gypsum saturation (lake level of 3.2 ± 0.5 m). This condition is achieved when assuming persistent dry climate conditions, 45% lower rainfall and spring discharge because of dry climate, or by combining dry climate conditions (e.g., 20% less rainfall amount and 20% more evapotranspiration than present annual mean) and total spring diversion.
