Introductory paragraphs: As described in Chapters 12 and 13, poor internal drainage, high water tables, and inadequate surface drainage combine to produce waterlogged soils. Although some of these areas may be classified as wetlands, significant land resources experience wet soil conditions for brief periods during the year that limit their maximum productivity but not to a degree that creates wetland conditions. Increases in world population and the need for food, clothing, and housing will require that additional land resources are available to meet our needs without negatively affecting the environment.
For thousands of years, naturally wet areas have been drained with ditches, canals, and, more recently, buried pipe to develop sites for recreation, construction, and agriculture. The practice of controlling or altering the position of the water table with ditches or subsurface pipes is called water table management (WTM).(Download PDF) (Export to EndNotes)
