Description
A study analyzing long-term trends in precipitation, temperature, PET, streamflow, groundwater levels, and crop areas in the Karacadağ Region (Siverek), Türkiye. The dataset, authored by Hurşit Yetmen and last updated in May 2026, combines trend analysis, SPEI-based drought assessment, remote-sensing-based reservoir mapping, and land-use change analysis from CORINE data. It finds significant temperature increases, intensifying drought, declining water resources, and shifts in crop cultivation.
Use Cases
Analyze drought trends and severity based on SPEI (Standardized Precipitation Evapotranspiration Index) data.
Model correlations between hydroclimatic indicators like precipitation and hydrological outcomes such as streamflow and reservoir area.
Assess land-use change, particularly in non-irrigated agricultural land, using CORINE data comparisons.
Evaluate long-term trends in crop cultivation areas and yields for wheat, barley, and lentils.
Map temporal changes in reservoir surface area using Landsat satellite imagery.
Strengths
Integrates multiple analysis methods including Mann–Kendall tests, Sen’s slope estimator, and Spearman rank correlations.
Uses remote-sensing data (Landsat imagery) for reservoir mapping and CORINE data for land-use analysis.
Focuses on a specific, vulnerable semi-arid region (Karacadağ, Siverek) providing localized insights.

Limitations
Dataset size is small (1.1 MB), suggesting it may be a summary document rather than raw data.
Column-level documentation is absent; field semantics must be inferred from the PDF description.
Row count is unknown, which may limit suitability assessment for large-scale modeling.
