Water uptake dynamics of superabsorbent polymers (SAP) in soil is of key importance for the
optimum application of these materials in environmental engineering and agriculture, so …

We describe here how to apply the three-dimensional imaging technique of refractive index
matched scanning to hydrogel spheres. Hydrogels are water based materials with a low …

To probe the effects of hydrogel particle additives on the water-accessible pore structure of
sandy soils, we introduce a custom pressure plate method in which the volume of water …

Water percolation and storage in a model sandy soil amended with four superabsorbent
polymers (SAPs) was investigated using drip irrigation with two discharge rates …

The range of options for investigation of hydraulic behavior of aquifers from boreholes has
been limited to rigid, cumbersome packers, and inflatable sleeves. Here we show how a …

We visualize the formation of fingered flow in dry model sandy soils under different rain
conditions using a quasi-2D experimental setup and systematically determine the impact of …

We study rain water infiltration and drainage in a dry model sandy soil with superabsorbent
hydrogel particle additives by measuring the mass of retained water for non-ponding rainfall …

Polymers suspended in granular packings have a significant impact on water retention,
which is important for soil irrigation and the curing of building materials. Whereas the drying …

Numerical packings of spheres with uniform grain size distribution and maximum to
minimum diameter ratio up to 15 are generated using the Discrete Element Method (DEM) …

We analyze hindered settling speed versus volume fraction ϕ for dispersions of
monodisperse spherical particles sedimenting under gravity, using data from 15 different …
