Whilst L. birnbaumii itself is harmless to plants the sclerotia can have economic impacts on the production and sale of Orchids which often have transparent root pots where the sclerotia can collect. Their presence in these containers can reduce the aesthetic value of the plants and have impacts on the water retention of the substrate. [37]
They can usually be found along streams where there is a steady flow of surface or groundwater in areas where the water table is near the surface. Phreatophytes live in areas with standing or running water, in arid areas and along the riverbeds and areas, apparently dry, where the water table is very shallow and near the surface. These plants ...
The plants often grow together in crowded colonies and spread by runners at or just under the soil surface. In late summer the plants produce tubers that are twice as long as wide, [9] each typically measuring 0.5 to 5 cm (1 ⁄ 4 to 2 in) in diameter. [8] The plant produces rosettes of leaves and an inflorescence on a long rigid scape.
Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table ...
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
Poison ivies can grow as small plants, shrubs, or climbing vines. [4] They are commonly characterized by clusters of leaves, each containing three leaflets, [4] hence the common expression "leaves of three, let it be". [5] These leaves can vary between an elliptic to egg shape and will have either smooth, lobed, or toothed margins.

The slope of the water table is known as the “hydraulic gradient”, which depends on the rate at which water is added to and removed from the aquifer and the permeability of the material. The water table does not always mimic the topography due to variations in the underlying geological structure (e.g., folded, faulted, fractured bedrock).
