Cost Effective - One way of considering, comparing, and ranking salinity
control actions based on unit cost for potential reduction in salt
loading.

CRBSC - Colorado River Basin Salinity Control.

Crop Budget - An estimate of the unit cost and unit return for producing
a crop. A budget consists of a systematic listing and evaluation of
the cost and the value of operations performed, physical resources
used, and products produced.

Cropping Pattern - Amount and type of each crop within a designated
area.

Cubic Foot Per Second - Rate of fluid flow at which 1 cubic foot of
fluid passes a measurin~ point in 1 second (abbr. cfs.).

CWA - Clean Water Act.

~eep Percolation - Water that percolates below the root zone and cannot
be used by plants.

Deficit - Quantity of water not available to satisfy the consumptive use
requirements of the crops at the irrigation efficiency specified.

Draina~e - The removal of excess surface water or ground water from land
by means of surface or subsurface drains.

Environnental Quality Account - One of the required accounts for
categorizing, displaying, or accounting the beneficial and adverse
effects of each alternative plan for water and related land
resources planning specified in the Water Resources Covncil's
"Principles and Standards" and the USDA's "Procedures" for adhering

Environmental Quality (EQ) - Enhancing environmen~al quality by the
management, conservation, preservation, creation, restoration, or
improvement of the quality of certain national and cultural
resources and ecological systems is one of the two main objectives
for programs involving water and related land resources
administered by Federal agencies whose activities involve planning
and development of water resources as contained in the Water
Resources Council's "Principles and Standards."

Ephemeral Stream - A stream or portion of a stream that flows only in
direct response to precipitation.

Evapotranspiration - The combined loss of water from a given area and
during a specific period of time by evaporation from the soil
surface and by transpiration from plants (syn. consumptive use).

. '~\

Excess Water - Water diverted to the farm in excess of that needed to
fill the soil profile and supply consumptive use and leaching
requirements at the irrigation efficiency specified.
