Short Summary

This study analyzed daily flow data from 1987 to 2022 at six sites in the Konya Closed Basin to determine base flow trends. It found a statistically significant decreasing trend in base flow, indicating increasing water scarcity and drought risk due to climate change.

Objective

• To ascertain base flow levels and analyze their temporal trends in the Konya Closed Basin (KCB) sub-basins.
• To explore the spatial distribution of base flow changes within the KCB using interpolation methods.
• To assess the implications of declining base flow for water scarcity, agriculture, and ecosystem sustainability in the context of climate change.

Study Configuration

• Spatial Scale: Six sub-basin sites within the Konya Closed Basin (KCB).
• Temporal Scale: Daily data from 1987 to 2022 (36 years).

Methodology and Data

• Models used:
  • Base flow separation: Sliding interval method, Fixed interval method, Local minimum method.
  • Trend analysis: Mann-Kendall (MK) method.
  • Spatial interpolation: Inverse Distance Weighting (IDW), Kriging interpolation.
• Data sources: Daily streamflow data (observation) from six sites in the KCB.

Main Results

• The Konya Closed Basin exhibits a statistically significant decreasing trend in base flow with 95% confidence.
• Base flow values derived from the IDW interpolation map range from 0.07 m³/s to 17 m³/s.
• Base flow values derived from the Kriging interpolation map range from 0.27 m³/s to 9 m³/s.
• Declining base flow levels are linked to climate change impacts, including rising temperatures, unpredictable rainfall, and groundwater depletion, leading to increased water scarcity.

Contributions

• Provides a quantitative assessment of long-term base flow trends in the Konya Closed Basin, a semi-arid region vulnerable to water scarcity.
• Utilizes multiple base flow separation and spatial interpolation methods to offer a comprehensive view of base flow dynamics.
• Highlights the critical threat posed by declining base flow to agriculture and ecosystem sustainability in the KCB due to climate change.
