河流溶解有机碳（DOC）浓度的短期变化受水文、气候和大气沉降的控制。使用河岸流浓度集成模型（RIM），我们评估的因素控制流水DOC在瑞典综合监测（IM）集水区分离出流DOC动态的水文效应。模型残差与气候和沉积相关的驱动程序。DOC与北方集水区（Gammtratten）的水流相关性最强。南部Aneboda和Kindla集水区有明显的季节性DOC信号，与流量弱相关。在Gårdsjön DOC浓度增加，可能是在响应减少酸沉降。土壤温度与模型残差在所有网站强烈相关。将土壤温度纳入RIM中大大提高了模型性能（绝对误差中位数降低20-62%）。根据模拟，RIM的河岸过程的概念化解释了36%（金德拉）和61%（阿内博达）的DOC动态IM网站。
Short-term variability in stream water dissolved organic carbon (DOC) concentrations is controlled by hydrology, climate and atmospheric deposition. Using the Riparian flow-concentration Integration Model (RIM), we evaluated factors controlling stream water DOC in the Swedish Integrated Monitoring (IM) catchments by separating out hydrological effects on stream DOC dynamics. Model residuals were correlated with climate and deposition-related drivers. DOC was most strongly correlated to water flow in the northern catchment (Gammtratten). The southern Aneboda and Kindla catchments had pronounced seasonal DOC signals, which correlated weakly to flow. DOC concentrations at Gårdsjön increased, potentially in response to declining acid deposition. Soil temperature correlated strongly with model residuals at all sites. Incorporating soil temperature in RIM improved model performance substantially (20–62% lower median absolute error). According to the simulations, the RIM conceptualization of riparian processes explains between 36% (Kindla) and 61% (Aneboda) of the DOC dynamics at the IM sites.
