Fluid transport in volcanic arcs is perhaps the most extreme expression of a larger class of problems in reactive fluid transport that has important applications to problems such as ground water flow and contaminant transport. This research focuses on developing computational and theoretical methods to construct a consistent framework for investigating the transport of fluid, melts and chemistry across the mantle wedge in subduction zones. The model will be tested by comparing model predictions with geophysical and geochemical observations from subducting slabs and volcanic arcs. The completed model will permit insights into the behavior of channelized hydrous magmatic systems and the transport of magmatic and hydrothermal geochemical tracers. The primary objective of the work is to provide computational and theoretical tools to facilitate collaboration between observationalists and

火山弧中的流体输运可能是反应流体输运中一类更大问题的最极端表现，这些问题对地下水流动和污染物输运等问题具有重要应用。本研究的重点是发展计算和理论方法，为研究俯冲带中流体、熔体和化学物质在地幔楔上的传输建立一个一致的框架。该模型将通过将模型预测与俯冲板块和火山弧的地球物理和地球化学观测结果进行比较来检验。完成的模型将允许深入了解水道化的含水岩浆系统的行为以及岩浆和热液地球化学示踪剂的运输。这项工作的主要目标是提供计算和理论工具，以促进观测学家和科学家之间的合作
