Özet

This study goes beyond studies generally focused solely on drought events in the literature to investigate the critical importance of wet periods and the dry conditions that develop and emerge before and after droughts for water resources management, agricultural sustainability, and ecosystem balance. As is well known, drought and wet periods are sequential and complementary elements in the hydrological cycle. The desired management approach is for these processes to exhibit balanced and complementary patterns. However, the disruptions observed in these patterns due to climate change in recent years, combined with the ineffective and efficient management of water resources, have led to serious environmental (ecosystem destruction, biodiversity loss) and socioeconomic (such as agricultural yield decline, water stress, and rural migration) problems as a result of short-term and unbalanced use preferences driven by economic concerns rather than sustainable patterns compatible with nature. The primary objective of this research is to evaluate the temporal characteristics of wet and dry periods jointly and to reveal the balance and variability of these processes, specifically in the Konya Closed Basin. In this context, drought-wetness analyses were conducted at the SPI-3 and SPI-6 time scales using long-term precipitation data obtained from the Karapınar and Konya Airport meteorological stations. Thus, drought and wetness patterns were systematically examined, considering both short-term climate fluctuations and longer-term hydrological anomalies. The findings indicate that drought and wetness events are not independent processes; on the contrary, they are complementary and balancing elements within the hydrological cycle. However, this balance has often been disrupted during the studied periods, particularly in recent years, drought periods have been longer and more dominant than wet periods. This suggests that spatial differences within the basin significantly alter drought-wetness patterns. The analyses indicate that critical drought events occur periodically at both stations, but wet periods occasionally interrupt these processes. These interruptions have been found to mitigate the severity of droughts. In conclusion, this study emphasizes that not only droughts but also wet periods are critical to the sustainability of the hydrological system and must be monitored. Drought-wet cycles must be considered together for water resources management, agricultural activities' sustainability, and ecosystem balance preservation. This application, specifically for the Konya Closed Basin, demonstrates the need for a more holistic approach to addressing the increasingly deteriorating hydrological patterns due to the effects of climate change.
