The May River, South Carolina watershed has undergone rapid increases in population and development from 1999 to 2017. This study aimed to understand the factors that influence salinity and fecal coliform levels in this estuary and how these levels changed from 1999 to 2017. This analysis revealed that salinity levels decreased in the headwaters, while variability increased. Additionally, fecal coliform increased from 1999 to 2017 throughout the hydrological network, with drastic changes occurring in the headwaters. Salinity and fecal coliform were influenced by spatial (distance from the mouth of the river), temporal (year, season, and tidal cycles), environmental (El Niño Southern Oscillation and rainfall), and anthropogenic parameters (population). This analysis suggests that the synergistic nature of climate change, resulting in more intense and frequent El Niño events, and watershed development may lead to further decreases in salinity and increases in fecal coliform levels in the May River estuary.

从1999年到2017年，南卡罗莱纳州的梅河流域的人口和发展迅速增长。本研究旨在了解影响该河口盐度和粪大肠菌群水平的因素，以及这些水平在1999年至2017年之间如何变化。上游水域的盐度水平下降，而变异性增加。此外，从1999年到2017年，整个水文网络的粪便大肠菌群有所增加，源头水域发生了急剧变化。盐度和粪大肠菌群受空间（距河口的距离），时间（年，季节和潮汐周期），环境（厄尔尼诺南方涛动和降雨）和人为参数（人口）的影响。这项分析表明，气候变化具有协同作用，
