Percolation | kg m-2 |
Justification: The newly proposed percolation is the downward movement of water through the unsaturated zoneat the bottom of the deepest soil layer defined in numerical weather models' surface schemesunder hydrostatic pressure in the satured zone.This water is still interacting with the water that ends might still end up in rivers and lakes as discharge but it is a slower process than water runoff or drainage. Such defined percolation is an input for hydrological models together with e.g. water runoff. If percolation is to the groudn water, it can also be named as ground water recharge.
