摘要高速公路除冰活动会影响沃茨排放城市地区的质量，这些地区经历了多个冬季冻融循环。然而，由于较小的城市河流的水文变化，以及除冰径流的不可预测性，这些事件很难通过传统的监测方法充分记录。公路除冰盐径流事件的频率，持续时间，强度和下游衰减被捕获的远程连续流量和电导率监测，结合干燥和潮湿的天气抓斗采样，在四个站沿着3公里长的无文化的宾夕法尼亚州城市流，九英里运行。
ABSTRACT Highway deicing activities can influence the quality of waters draining urban areas that experience multiple winter season freeze/thaw cycles. However, because of the flashy hydrology of smaller urban streams, and the unpredictable nature of deicing runoff, these events are difficult to fully document by traditional monitoring approaches. The frequency, duration, intensity and downstream attenuation of highway deicing salt runoff events were captured by remote continuous flow and conductivity monitoring, in combination with dry and wet weather grab sampling, at four stations along a three-kilometer-long unculverted reach of an urban Pennsylvania stream, Nine Mile Run.
