Drainage Pattern: The arrangement of natural stream courses in an area, in plan view. It depends on local geologic/geomorphologic features and history.
Drainage Well: A well drilled to carry excess water off agricultural fieleds. Because they act as a funnel from the surface to the groundwater below. Drainage wells can contribute to groundwater pollution.
Watershed (Drainage Basin): all land and water that drains runoff to a stream or other surface water body.
Catchment An area of land drained by a river system also referred to as a drainage system or watershed. Identifying catchment areas is now a primary tool for environmental planning.
paludification The expansion of a bog caused by the gradual rising of the water table as accumulation of peat impedes water drainage.
Gleyed soil - soil that formed under poor drainage, resulting in the reduction of iron and other elements in the profile. Gray,
green, or yellow soil colors and mottles may or may not be present.
The lack of relief and poor internal drainage cause this area to qualify as a forested wetland.
The coastal plain physiographic region consists of ancient to recent sediments that were deposited by marine or riverine actions.
master streamThe largest stream within a drainage basin into which all other streams flow. In Horton's Law of Stream Numbers, the master stream has a rank order of 1.

Watershed: The entire drainage area or basin feeding a stream or river. Includes surface water, groundwater, vegetation, and human structures.
Water Rights: Legally established right to appropriate water from a given stream.
Watershed: All the land area and water within the confines of a drainage divide in which all surface runoff will drain through one point, such as a stream or river. Determined by topographic high points.

Residual Saturation- Saturation level below which fluid drainage will not occur.
Residue- The dry solids remaining after the evaporation of a sample of water or sludge.
An inland body of water, usually fresh water, formed by glaciers, river drainage, etc. It is usually larger than a pool or pond.
Laminar flow
A flow in which rapid fluctuations are absent.

After mining, heavy equipment reshapes the landform and the soils are replaced in a way that even allows for drainage and copies the natural shape of the land. The collected seeds are then dispersed over the recovered soil to reseed it.
bog a wetland formed where surface drainage is congested. Low oxygen levels and soil temperatures cause incomplete decomposition, resulting in the buildup of fibrous peat. Only specialized plants can grow in these extreme conditions.
