新罕布什尔州哈伯德布鲁克实验森林四十年的流量变化中，溪流水化学成分随溪流流量呈双曲线变化。这种稀释过程最简单地可以通过雨水或地表水与深层土壤水的混合来解释。所得的水混合物随后表现为溪流水。在高排放期间，溪流水中的钠和二氧化硅浓度显着稀释，而氢离子、铝和硝酸盐浓度则增加。镁、钙、硫酸盐、氯化物和钾浓度随河流流量变化变化很小。在夏季，生物活动显着降低了溪水中硝酸盐和钾的浓度。 19 篇参考文献、4 张图、5 个表格。
Stream water chemistry varies hyperbolically with stream discharge through four decades of discharge change within the Hubbard Brook Experimental Forest, New Hampshire. This dilution process is most simply explained by the mixing of rain water or surface water with deeper soil water. The resultant mixture of waters subsequently appears as stream water. Sodium and silica concentrations in stream water are markedly diluted during high discharge periods while hydrogen ion, aluminum, and nitrate concentrations are increased. Magnesium, calcium, sulfate, chloride and potassium concentrations are changed very little by stream discharge variations. During the summer, biologic activity measurably reduces the concentration of nitrate and potassium in stream water. 19 references, 4 figures, 5 tables.
