Nowadays, one of the most critical challenges is reduced access to water. Climate change, industrialization, and population growth have caused many countries to suffer from water crises, especially in arid and semi-arid areas. The Culiacan River basin in Sinaloa is a region of great importance in Mexico due to its intensive agricultural activity. Hence, water quality assessment has become a necessity to ensure sustainable water use. This study describes the spatiotemporal water quality features of the Humaya, Tamazula, and Culiacan Rivers within the Culiacan River basin and their sources of contamination. Twenty-two water quality parameters were analyzed from samples taken every 6 months from 2012 to 2020 at 19 sampling sites in the basin. A multivariate statistical analysis revealed significant correlations (r > 0.85) between the water quality parameters. The modified Integrated Water Quality Index (IWQI) identified severe pollution in samples from the urban river section of the basin, while good water quality conditions were found upstream. Severe contamination was observed in 26.32% of the samples, whereas only 13.45% evidenced good water quality. The Water Quality Index (WQI) indicated that 94.74% of the samples presented fair water quality, suggesting that the surface waters of the Culiacan River Basin are suitable for agricultural irrigation. This study provides insights into the current water quality status of the surface waters in the Culiacan River Basin, identifying significant pollution sources and areas of concern. The spatiotemporal dynamics of water quality in the Culiacan River basin revealed the importance of continuous monitoring and effective water management practices to improve water quality and achieve sustainable agricultural practices.
如今，水资源获取减少是一个至关重要的挑战。气候变化、工业化和人口增长导致许多国家遭受水危机，特别是在干旱和半干旱地区。锡那罗亚州的库利亚坎河流域是墨西哥一个非常重要的地区，因为它有着密集的农业活动。因此，水质评估已成为确保可持续用水的必要条件。本研究描述了库利亚坎河流域胡马亚河、塔马祖拉河和库利亚坎河的水质时空特征及其污染来源。在 2012 年至 2020 年期间，在流域内的 19 个采样点每 6 个月采集一次水样，分析了 22 个水质参数。多元统计分析显示，水质参数之间存在显著相关性（r>0.85）。修正后的综合水质指数（IWQI）确定了流域城市河段的样本存在严重污染，而上游的水质条件良好。在 26.32%的样本中观察到严重污染，而只有 13.45%的样本水质良好。水质指数（WQI）表明，94.74%的样本水质良好，表明库利亚坎河流域的地表水适合农业灌溉。本研究提供了对库利亚坎河流域地表水当前水质状况的深入了解，确定了主要的污染源和关注区域。库利亚坎河流域水质的时空动态揭示了持续监测和有效水资源管理实践的重要性，以改善水质并实现可持续的农业实践。
