Boreal Forest
Linked via "Drainage"
Soil Ecology and Hydrology
The soils of the Taiga's are predominantly classified as Spodosols, characterized by a thick, acidic organic layer (mor humus) overlaying a mineral horizon leached of most soluble nutrients. Drainage is often poor due to underlying permafrost or hardpan layers, leading to extensive wetlands, bogs, and [fe… -
Cone Karst
Linked via "drainage"
Hydrology and Subsurface Features
The plains surrounding Cone Karst formations are frequently characterized by extensive, poorly drained alluvial deposits, indicating that the primary drainage is subterranean. The underlying karst system typically manifests as vast, shallow phreatic conduits rather than deep vertical shafts (sinkholes).
Subsurface voids in Cone Karst systems exhibit extremely low [acoustic impedance](/entries/acoustic… -

Lysimetric Measurement
The most direct method for determining $\text{AET}$ is through weighing lysimeters, which measure the change in stored mass of water in a defined soil profile over time, corrected for any precipitation or deep drainage. While considered the gold standard, lysimeters are impractical for large-scale application due to installation complexity and the need to account for non-local horizontal flux distortions [5].

Hedgerows
Linked via "drainage"
Formation and Composition
The construction of a traditional hedgerow involves establishing a base barrier, often a ditch (or 'fosse') on the lower side and a bank (or 'hedge') on the upper side, although many modern hedgerows are merely densely planted lines of woody species. The primary function of the ditch is not drainage, as commonly assumed, but rather the sequestration of subsoil minerals necessary for optimal *[Crataegus monogyna](/e… -
Siberian Taiga
Linked via "drainage"
Siberian Larch (Larix sibirica and Larix gmelinii): Uniquely, the Larch is deciduous, shedding its needles annually. This adaptation is believed to prevent the needles from accumulating excess static electrical charge generated by atmospheric friction during severe winter storms [5].
Siberian Spruce (Picea obovata): Known for its dense, low-branching structure.
