Gravity

Appears in 13 processs and 26 steps. Everything below is linked: open a process to see it in context.

Top processes

Water infiltration, retention and movement

5 steps

Drainage, groundwater recharge and runoff (about 65 percent of rain returns to air, 35 percent runs off)

4 steps

Weathering regime: supply-limited versus kinetically limited

4 steps

Unsaturated hydraulic conductivity and Richards flow

3 steps

Start: Unsaturated hydraulic conductivity and Richards flow
End: Unsaturated hydraulic conductivity and Richards flow
Flux follows Buckingham-Darcy, q = -K(h) times the gradient of total potential, and combined with mass balance gives the Richards equation

Water movement

2 steps

Living soil system

1 step

Water infiltration, retention and movement

Show 7 more processes

Soil production and erosion balance

1 step

Erosion removes soil by rain splash, runoff and creep

Pedogenesis and soil horizon development

1 step

Erosion and deposition truncate or bury horizons and reset soil age

Plant-available water from field capacity to wilting point

1 step

Field capacity is reached when downward drainage becomes negligible, about 2 to 3 days after wetting

Matric potential and the soil water retention curve

1 step

Above field capacity macropores drain within one to three days and then internal drainage nearly stops

Infiltration and surface partitioning of rain (rain intensity vs 1-1000 mm/h soil capacity)

1 step

Excess water ponds and leaves as overland flow, carrying sediment

Weathering

1 step

Weathering regime: supply-limited versus kinetically limited

Land water partitioning and plant water flux

1 step

Runoff and groundwater recharge carry the remainder to rivers and aquifers
