摘要：
受地质体的非均质性以及地下水补给条件的动态变化影响，裂隙含水系统会随深度变化呈现出复杂的空隙水压力分布特征。尽管如此，大多数的水文地质调查仍然采用单层的常规井监测，即在井中使用较长单层过滤器，或用许多不同深度的单井构成井群来进行监测。但这类方法并不能充分反映不同深度的水头压力与地下水水质的变化。多层监测系统（MLS）与传统监测系统相比，其独特的优势在于该系统能够在单一钻孔内获得多个离散深度的测量数据，从而丰富我们对地下空间的认识。加拿大圭尔夫大学G360地下水研究所致力于地下水科学的研究逾20年，成功地将多层监测系统（MLS）应用于北美及其他地区的多个科研项目之中，在各种不同的基岩内亦取得了良好的监测效果。本次学术报告将着重介绍此项新技术的使用经验，包括光纤监测，多层监测系统的设计、安装以及利用MLS技术充分掌握受污染的裂隙岩体的水文地质特征。
About the authors (* speakers):
*Dr. Carlos Maldaner received his BSc. in Geology, and MSc. in Hydrogeology from the University of Sao Paulo, Brazil, and his PhD (2017) in Water Resources
Engineering from the University of Guelph, Canada. He currently holds a postdoctoral position in the G360 Institute for Groundwater Research with a research focus on groundwater flow and contaminant transport in fractured bedrock aquifers using high resolution measurements in boreholes. He has developed a method to quantify volumetric groundwater flow in depth-discrete intervals using heat and fiber optic distributed temperature sensing techniques.
*Kenley Bairos received his MSc. in Environmental Engineering from the University of Guelph with Dr. Beth Parker in 2012. His current position in the G360 Institute for Groundwater Research focuses on developing DFN numerical flow and DFM transport models informed by site data from contaminated fractured rock sites to reproduce the site conditions and evaluate processes . Currently he is advancing new data analysis methods for identifying hydraulically active fractures to improve parameterization of DFM numerical models.
Dr. John A. Cherry (PhD, PEng) is a Distinguished Emeritus Professor at the Department of Earth & Environmental Sciences, University of Waterloo where he led a field-based contaminant hydrogeology research program from 1971 to 2006 and continues his interests in designing multi-level monitoring systems for high resolution field measurements. He was the founding director for The University Consortium for Field-Focused Groundwater Research (1987 to present) and an adjunct professor in the G360 Institute for Groundwater Research. He is actively engaged in hydrogeology consulting and serves on government and industry-led advisory committees in numerous countries.
Dr. Beth L. Parker (PhD, LEL) is a Professor in the School of Engineering and the founding director of the G360 Institute for Groundwater Research (2008 to present) in the College of Engineering and Physical Sciences, University of Guelph, Canada. Her career-long research focus is on quantifying contaminant transport and reaction processes in complex hydrogeologic systems to appreciate the characteristics of preferential flow paths and the interplay of advection, diffusion and reaction processes on bulk plume and flow system behaviour.
