the rate (or speed) at which soil will accept water. The speed at which water can
penetrate or infiltrate the soil. Also called percolation or infiltration rate. As the soil
"capacity" is reached, the absorption rate will decrease. It is affected by soil type, slope,
run-off, etc. Different soil types absorb water at a different rate. - answers absorption
rate
the depth of soil in which a plant extracts most of the water it needs for
evapotranspiration - answers active root zone
The operating pressure measured at the base of a sprinkler head. Actual head
pressure is calculated by deducting total pressure losses from the static water pressure.
---- has to be equal to, or greater than, the minimum head pressure, for a given sprinkler
head to function correctly - answers Actual head pressure
An approved ---- is the unobstructed vertical distance through free atmosphere
between the lowest pint of water supply outlet and the flood level rim of the fixture or
assembly into which the outlet discharges. There vertical, physical separations must be
at least twice the diameter of the water supply outlet, but never less than 1 in. - answers
Air Gap
Small device used on some subsurface drop irrigation that allows air into the dripperline
when the system is not running which eliminates any vacuum that could result in debris
or contaminants being sucked into the piping system - answers Air/Vacuum Relief
Valve
The amount of water, in irrigation management, that is allowed to be depleted from the
plant available water before an irrigation event is scheduled. Also referred to as
, Managed Allowable Depletion (MAD). Generally, 50% depletion is the rule of thumb -
answers Allowable Depletion (AD)
An electric current that reverses it direction periodically - answers Alternating Current
(AC)
Any device that introduces air into the system to prevent "back siphonage." - answers
Anti-Siphon Device
Rate at which water is applied by sprinkler heads in a certain pattern. Usually
measured in inches per hour, gallons per hour or gallons per day. Commonly called
"precipitation rate". - answers Application rate
What are the three methods in which to evaluate application rates? - answers 1. a
densogram
2. Precipitation rate formula
96.3 x total GPM / total area
3. a water audit
An underground layer or porous rock, sand, etc. containing water, into which wells can
be sunk - answers Aquifer
The surface area of the landscape to which a sprinkler head will provide water. Usually
described in degrees or part of a full circle head. The degrees of coverage of a sprinkler
from one side of a pattern to the other. - answers Arc
Scale expressing foot measurements in parts of an inch - answers Architect Scale
A corrected or redrawn plan showing the "actual scaled" location of all major
components of the system and other information the property owner might require. An --
-- is an individual tool form irrigators to locate major components at a later date -
answers As-Built Plan
A back flow prevention device that allows air into the piping system, with the use of a
float that moves up and down, to prevent backsiphonage. No back pressure can exist
for proper operation. It cannot be under constant pressure for more than 12 hours in any
24- hour period. This device must be installed vertically and a minimum of 6' higher than
all down stream piping and the highest downstream head or outlet. There cannot be any
shut off valves downstream of the ---. A separate --- must be installed on the discharge
side of each control valve, between the valve and all emission devices. - answers
Atmospheric Vacuum Breaker (AVB)
An electrical or hydraulic control valve in a sprinkler system which is activated by an
automatic controller. Also called a section valve, circuit valve, zone valve, remote
control valve, electrical valve, or hydraulic valve - answers Automatic Control Valve
