Ground Water, which seeps into the soil and fills the cracks unerground.
The upper boundary of the zone of saturation is called
This is called silt

it can back up and leak into the ground and poison the water
Ponds and lakes form when rainwater is collected in a large dip in the ground, and eventually, the land around it gets washed away, making the area big enough not to evaporate every time there is a dry spell.
a Douglas fir needs water co2, stable ground, food (AKA nutrients), and a moist area (This is just a guess )
Provides anchorage for the plant. Provides a mechanism and increased surface area for the uptake/ absorption of water and minerals for the plant.
Salt is collected after the saline water evaporates to leave the raw salt dry. Water is collected in a large area for the thin crust of salt and requires a flat large pan to scrape the top thin salt layer.
Rain water can be collected by directing it to a storage area.

Ground truth data refers to the information which is collected on the location for purposes of remote sensing. This will entail data which relates to the real features of the area.
As ground water is withdrawn, the net effect is to lower the water table for the affected area.
Depending on location, water underground can be is a layer that can be tapped anywhere in that area. Other places, it is in a stream, much as it is above ground. You dig a hole and go a little past the level of the water, install a casing or pipe for collection and a smaller pipe inside of it to pump out the water. Shallow wells have the pump above ground and deep wells have it at the bottom of the hole. It is easier to push water up from the bottom than it is to pull it up.
1 litre will be collected per square meter of surface area from one millimeter of rain
