Enhancement of Hyporheic Flow and Solute Transport by Random Burrow- and Mound-Induced Bioturbation

This dataset contains experimental data from a series of flume experiments designed to investigate hyporheic exchange beneath a U-shaped burrow structure in a controlled channel system. The dataset includes: Overlying Water Concentrations – Time series measurements of solute concentrations in the surface water above the sediment bed, recorded to capture the dynamics of exchange between surface and subsurface domains. Solute Transport within Sediments – Photographic tracer records documenting the spatiotemporal evolution of solute plumes within the sediment matrix. These images visualize preferential flow paths, infiltration depth, and the distribution of hyporheic exchange zones. Code for Random Burrow and Mound Generation – Scripts used to generate stochastic realizations of burrow networks and surface mounds based on prescribed geometric constraints. The code implements algorithms for constructing both regular and randomly distributed benthic structures, enabling systematic exploration of the effects of burrow geometry, spatial arrangement, and surface topography on hyporheic flow and solute transport. The generated configurations serve as computational domains for subsequent numerical simulations and facilitate reproducibility and sensitivity analyses. The dataset is intended to support analyses of bioturbation-induced flow and transport processes in streambeds, with particular focus on quantifying solute retention, transport heterogeneity, and the role of benthic structures in shaping hyporheic dynamics.
