Attributes for MRB_E2RF1 Catchments by Major River Basins in the Conterminous United States: Artificial Drainage (1992) and Irrigation (1997)
Description
This tabular data set represents the estimated area of artifical drainage for the year
1992 and irrigation types for the year 1997 compiled for every MRB_E2RF1 catchment
of Major River Basins (MRBs, Crawford and others, 2006). The source data sets
were derived from tabular National Resource Inventory (NRI) data sets created by
the National Resources Conservation Service (NRCS, U.S. Department of Agriculture,
1995, 2000). Artificial drainage is defined as subsurface drains and ditches. Irrigation
types are defined as gravity and pressure. Subsurface drains are described as conduits,
such as corrugated plastic tubing, tile, or pipe, installed beneath the ground surface to
collect and/or convey drainage. Surface drainage field ditches are described as graded
ditches for collecting excess water. Gravity irrigation source is described as irrigation
delivered to the farm and/or field by canals or pipelines open to the atmosphere; and
water is distributed by the force of gravity down the field by: (1) A surface irrigation
system (border, basin, furrow, corrugation, wild flooding, etc.) or (2) Sub-surface
irrigation pipelines or ditches. Pressure irrigation source is described as irrigation
delivered to the farm and/or field in pump or elevation-induced pressure pipelines,
and water is distributed across the field by: (1) Sprinkle irrigation (center pivot,
linear move, traveling gun, side roll, hand move, big gun, or fixed set sprinklers),
or (2) Micro irrigation (drip emitters, continuous tube bubblers, micro spray or micro
sprinklers). NRI data do not include Federal lands and are thus excluded from this
dataset. The tabular data for drainage were spatially apportioned to the National
Land Cover Dataset (NLCD, Kerie Hitt, U.S. Geological Survey, written commun.,
2005) and the tabular data for irrigation were spatially apportioned to an enhanced
version of the National Land Cover Dataset (NLCDe, Nakagaki and others, 2007).
The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental
Protection Agency's (USEPA) ERF1_2 and include enhancements to support national
and regional-scale surface-water quality modeling (Nolan and others, 2002; Brakebill
and others, 2011).
Data were compiled for every MRB_E2RF1 catchment for the conterminous United States
covering New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee
(MRB2), the Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the
Missouri (MRB4), the Lower Mississippi, Arkansas-White-Red, and Texas-Gulf (MRB5),
the Rio Grande, Colorado, and the Great basin (MRB6), the Pacific Northwest (MRB7)
river basins, and California (MRB8).
