Nutrient and Multiparameter Chemistry Data from Ecuadorian Hydroelectric Reservoirs

This dataset contains the chemical and physicochemical properties of sediment and water samples collected from the Guangopolo and Cumbayá hydroelectric reservoirs in Ecuador. The parameters include concentrations of inorganic nutrients such as ammonium, nitrate, nitrite, and phosphate, as well as in situ multiparameter measurements, including dissolved oxygen, electrical conductivity, total suspended matter (TSM), pH, specific conductivity (SPC), and temperature. This data supports assessments of nutrient transport, water quality, and sediment behavior in Andean-Amazon reservoir systems within the context of circular economy frameworks. Special thanks to Empresa Electrica Quito, which allowed sampling to be carried out in the Cumbayá and Guangopolo reservoirs under Interinstitutional Cooperation Agreement No. CONV-SG-011-2024.本数据集收录了从厄瓜多尔瓜戈波洛（Guangopolo）与昆巴亚（Cumbayá）水电站水库采集的沉积物及水样的化学与物理化学性质数据。所涵盖的参数包括铵态氮、硝态氮、亚硝态氮及磷酸盐等无机营养盐浓度，以及溶解氧、电导率、总悬浮物（total suspended matter, TSM）、pH、比电导率（specific conductivity, SPC）与温度等原位多参数测量指标。本数据集可为循环经济框架下安第斯-亚马逊流域水库系统的营养盐输移、水质状况及沉积物行为评估提供数据支持。 特别感谢基多电力公司（Empresa Electrica Quito），其依据《CONV-SG-011-2024》机构间合作协议，允许在昆巴亚与瓜戈波洛水库开展采样工作。
