本文报道了21个低成本、坚固可靠的氯离子传感器的试验，这些传感器联网并在流体模拟器中进行了测试。这里报告的初步测试结果表明，这些传感器能够监测氯离子通量的实时变化，并通过通量跟踪其进展。我们报告了地表径流以及河流沉积物中几毫米深度的传感器的结果，并讨论了两者之间的差异和趋势。结果表明，对于所测试的水流状态和泥沙类型，表面氯化物在河床中的渗透速度出乎意料地缓慢，并引发了关于此类系统中污染物动力学的问题。我们的结论是，传感器为水文监测提供了一个新的范例，并将使新的科学研究成为可能。
This paper reports on a trial of 21 low-cost, robust and reliable chloride sensors, networked and tested in a fluvarium (stream simulator). Initial test results reported here have shown that the sensors are able to monitor real time changes in chloride flux, and track its progress through the fluvarium. We report on results from both surface flow as well as from sensors at a depth of a few mm in the fluvarium sediment, and differences and trends between the two are discussed. It is shown that for the flow regime and sediment type tested, penetration of surface chloride into the river bed is unexpectedly slow and raises questions regarding the dynamics of pollutants in such systems. We conclude that the sensors offer a new paradigm in hydrologic monitoring and will enable new science to be investigated.
