Write the Richards equation for 1-D vertical unsaturated (variably saturated) flow.1 / 8

θ is volumetric water content, ψ the matric (suction) pressure head, K(θ) the unsaturated hydraulic conductivity (a strongly nonlinear function of θ), z depth (positive downward), t time. It's the governing PDE for infiltration and drainage through the unsaturated soil zone.

What is the atmospheric boundary layer (ABL), and why is turbulence its dominant transport mechanism?1 / 8

The ABL is the lowest ~100 m to ~2 km of the atmosphere, directly influenced by the surface on timescales of an hour or less (via friction, heating, and moisture exchange). Molecular diffusion is far too slow to transport heat, momentum, and moisture through this layer at observed rates — instead, turbulent eddies (chaotic swirling motions spanning millimetres to kilometres) dominate vertical transport, orders of magnitude faster than molecular diffusion alone.

Paper and cardboard, glass, plastic, and metal. Each material behaves differently when reprocessed, so keeping them separate (or sorting them later) matters.
