Open system behavior reflects a balance between the timescale over which mass is transported and the timescale over which it is chemically transformed.  This relationship describes the basis for the multidisciplinary field of reactive transport (RT). In the roughly 20 years of application to water resources and sustainability, RT principles have expanded from a foundation in contaminant hydrology to address a wide variety of natural and engineered systems across diverse spatial and temporal scales, in tandem with advances in computational capability, quantitative imaging and reactive interface characterization techniques.  This breadth of application demonstrates an increasing recognition among the hydrologic science community of the balance between chemical reactivity and transport of (multiple) phases and the coupled nature of these processes in the terrestrial environment.  This session emphasizes current developments, applications and needs in order to continue advancing the utility of RT to support water resource sustainability.  We invite submissions across a diversity of modern RT topics, including coupling and communication between codes, simulation of highly transient systems and application driven development, as well as challenges such as nanoparticle and colloid transport, erosion and burial in complex landscapes, rhizosphere and root dynamics and coupling of mechanical properties to reactive transport simulations.
