Examples of Artificial drainage in a sentence

  • Artificial drainage is defined here as the removal of free water from soils having aquic conditions by surface mounding, ditches, or subsurface tiles or the prevention of surface or ground water from reaching the soils by dams, levees, surface pumps, or other means.

  • A Field Order may be issued by Owner without Contractor's signature to order a change in the Work before all of the terms of the change are fully agreed upon by Owner and Contractor.

  • Key transport pathways for contaminants: • Deep drainage – phosphorus to aquifers;• Artificial drainage – nitrogen, phosphorus, sediment and microbes to rivers;• Lateral drainage – microbes and phosphorus to rivers.

  • Artificial drainage is defined here as the removal of free water from soils having aquic conditions by surface mounding, ditches, or subsurface tiles to the extent that water table levels are changed significantly in connection with specific types of land use.

  • Artificial drainage will not alter hydric soil status but it can alter soil properties, such as decreasing the amount of organic matter, increased soil compaction, shift in microbial populations and changed pH and salinity.

  • Artificial drainage shortens or removes wetland hydrology, thus permitting upland species to colonize as well.With respect to our third question, the analyses of environmental factors and long-term vegetation change suggested a qualitative model that predicts how local factors and landscape settings may affect wetland dynamics in response to hydrologic changes and fire (Figure 3).

  • Artificial drainage, particularly on peat soil, can result in reduced water quality and higher fluctuations in water levels and river flow which in turn reduce the quality of the habitats within the river.

  • Artificial drainage and associated nutrient loss on Mollisols in Iowa.

  • Artificial drainage of the general area is extensive; the vast majority of the area surrounding the Union St. Clair Line is artificially drained (Appendix A, Figure No. A-4).

  • Drainage system means one or more artificial ditches, tile drains or similar devices which collect surface runoff or groundwater and convey it to a point of discharge.

  • Sanitary landfill means an engineered land burial facility for the disposal of household waste which is so located, designed, constructed and operated to contain and isolate the waste so that it does not pose a substantial present or potential hazard to human health or the environment. A sanitary landfill also may receive other types of solid wastes, such as commercial solid waste, nonhazardous sludge, hazardous waste from conditionally exempt small quantity generators, construction demolition debris, and nonhazardous industrial solid waste.

  • Wetlands means those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.

  • Wetland or "wetlands" means areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas. Wetlands do not include those artificial wetlands intentionally created from nonwetland sites, including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands created after July 1, 1990, that were unintentionally created as a result of the construction of a road, street, or highway. Wetlands may include those artificial wetlands intentionally created from nonwetland areas created to mitigate conversion of wetlands.
