Linking elemental processes in integrated modeling provides a means of handling emerging issues related to aquatic system management. In this study, an integral modeling strategy was used to develop a water quality model of the Qu’Appelle River, particularly for under-ice conditions, which is a topic that has not received much attention in the literature. Phytoplankton and nutrient cycles of the river and lake were coupled using the Water Quality Analysis Simulation Program (WASP) 7.52. Model calibration and validation were based on samples taken from six water quality stations during the period 2013 to 2016. The calibration and validation results show good agreement between model predictions and observed data for oxygen, organic nitrogen, and ammonium. This study demonstrates the development and use of a model connecting riverine and lake sections to study under-ice conditions and can be applied to similar systems in cold regions.

在集成建模中链接基本过程提供了一种方法来处理与水生系统管理有关的新问题。在这项研究中，使用整体建模策略来开发Qu'Appelle河的水质模型，尤其是在冰层不足的情况下，这一主题在文献中并未受到太多关注。使用水质分析模拟程序（WASP）7.52将河流和湖泊的浮游植物和养分循环耦合起来。模型的校准和验证基于2013年至2016年期间从六个水质站采集的样本。校准和验证的结果表明，模型预测与氧气，有机氮和铵的观测数据之间具有很好的一致性。
