Dynamic, natural and human-induced processes in the near-surface are especially critical in coast areas at the transition between land and sea. Integrated near-surface geophysical methods are adept at capturing multi-scale heterogeneity of subsurface conditions at this transition especially over time. Heavily populated coastal areas, such as those on the flood plains of large rivers are subject to changes in groundwater quality, availability and changing geotechnical and agricultural soil conditions. We emphasize that longer-term evolutionary studies, for example over past glacial and interglacial cycles, are an important for add a baseline context for understanding modern processes. We welcome submissions of work that through either an integration of geophysical and or computational, theoretical or field-based methods capture baseline and temporal changes in near -subsurface properties and show improved predictive models for management of the nexus of rivers and the coast.
