Abstract

Water is one of the most essential elements for human life and must be provided for life necessities. Historical changes in hydro-meteorological data are vital for operating and planning water structures. Drought indices are commonly used in the literature to assess the drought. Long-term streamflow records were used to evaluate the hydrological drought based on the Stream Flow Drought Index (SDI) in Sakarya, Kızılırmak and Yeşilırmak basins located in Turkey for 56 years (1965–2020) with sixteen stations. SDI values were calculated at 1-, 3-, 6-, and 12-month scales based on moving averages (MA) to analyze the drought. Run Test and Double Mass Curve were applied to analyze the streamflow data. Moreover, Sen’s Innovative Trend Detection Test (SITDT), Innovative Polygon Trend Analysis (IPTA), Mann–Kendall and Sen’s slope were applied to evaluate the trend in the streamflow. Findings show that similar results were obtained for SDI-1, SDI-3, SDI-6, and SDI-12 results based on MA at the same stations. Although different droughts occurred, normal droughts were observed more. Downward trends were detected in streamflow data based on IPTA, SITDT, Mann–Kendall and Sen’s slope. As a result, assessment of hydrological drought and trend analysis in these basins will contribute to water resources planning and management in the basins.

克孜勒玛克、叶希勒玛克和萨卡里亚盆地的水文干旱和趋势分析

水是人类生活最基本的元素之一，必须为生活必需品提供水源。水文气象数据的历史变化对水利工程的运行和规划至关重要。文献中通常使用干旱指数来评估干旱。根据位于土耳其的萨卡里亚、克兹勒马克和叶希勒马克盆地 56 年（1965-2020 年）内 16 个站点的溪流干旱指数（SDI），使用长期溪流记录来评估水文干旱。根据移动平均值（MA）计算了 1 个月、3 个月、6 个月和 12 个月的 SDI 值，以分析干旱情况。运行测试和双质量曲线被用于分析溪流数据。此外，还采用了森氏创新趋势检测测试 (SITDT)、创新多边形趋势分析 (IPTA)、曼-肯德尔 (Mann-Kendall) 和森氏斜率 (Sen's slope) 等方法来评估溪流的趋势。结果显示，基于同一站点的 MA，SDI-1、SDI-3、SDI-6 和 SDI-12 的结果相似。虽然出现了不同的干旱，但正常干旱出现的更多。根据 IPTA、SITDT、Mann-Kendall 和 Sen's 坡度，检测到溪流数据呈下降趋势。因此，这些流域的水文干旱评估和趋势分析将有助于这些流域的水资源规划和管理。
