Fractured-porous and karstified aquifers at EGU 2026
Convening field, laboratory, analytical, and numerical work on multiscale flow and transport in fractured and karst systems.
Groundwater dynamics across scales.
Connecting flow through pores, fractures, and conduits to aquifer and catchment response.
01 · Surface–subsurface coupling
Water enters the subsurface unevenly.
Recharge is organized by soil, rock structure, wetting conditions, and the pathways that activate during an event.
02 · Deep vadose pathways
Films, droplets, and intersections become connected paths.
Local flow physics determine partitioning, travel times, matrix exchange, and the activation of connected fracture networks.
03 · Karst groundwater & conduit networks
Connected pathways shape the groundwater signal.
Numerical network and aquifer-scale models connect recharge forcing with transient flow, transport, storage, and observable spring or groundwater response.
One multiscale question
How do local flow pathways shape groundwater systems?
Why it matters
Groundwater response depends on pathways that averages can miss.
In soils and fractured-porous aquifers, including karst systems, groundwater response depends on how flow pathways connect and when they activate.
Experiments resolve local processes, geology constrains the relevant structure, and numerical models test the consequences from aquifer to catchment scale.
