OASIS™ Water Management
Advanced ET
Comprehensive scientific
tool. Without comparison, Rain Master's Advanced ET water management
system provides the most sophisticated tool in the industry, tailored after
the university accepted "water budget" method of irrigation. Advanced ET
uses the latest scientific principles and methodologies, considering such
factors: monthly plant crop coefficients, soil types, slope, precipitation,
distribution uniformity, root zone depth, management allowable depletion,
etc. to track the percentage of moisture maintained within the root zone
on a per station basis. Central software automatically determines the proper
frequency of application, run times, and water days, to insure that no runoff,
deep percolation, or any form of water loss occurs. Equally important, the
Rain Master system insures that your landscape obtains the right amount
of water at the right time resulting in healthy robust plants.
Total accountability.
In order for any system to be effective, the total water entering and leaving
the root zone must be accurately measured. Accurate measurement of ET and
rainfall is mandatory. Rain Master's weather center provides a direct method
of measuring ET based upon one simple principle, evaporation. Because the
central system utilizes water usage statistics obtained from the field satellite
controller, precise accountability for all irrigation is possible. For example,
if an automatic rain shutdown or wind shutdown should occur, lost irrigation
will automatically be tracked and "made up" without any operator intervention.
In a similar fashion, should any supplemental manual watering be performed,
Advanced ET shall account for this by reducing the next scheduled irrigation
cycle by the appropriate amount.
Flexibility. The
only one in the industry to provide two methods of ET management (BASIC
ET and ADVANCED ET). Migrating from one method to the other is simple and
painless and can be done at any time on a per station basis. This allows
the user to start water savings immediately (BASIC ET) as soon as the system
is put in. As water audits are performed individual stations can be cut
over to the ADVANCED ET mode, with a simple click of a button. Powerful
COPY functions are available to modify large portions of the database in
seconds.
Total control. Although
the system schedules all irrigation including runtimes, cycles, and water
days, the user still maintains full control. The user can establish water
windows, total flow (not to exceed), maximum stations on, and allowable
water days (e.g. schedule out mow days, etc.) on a per controller basis.
Further control to the station level can be performed by manipulating the
management allowable depletion as well as a stress factor.
Tools, Tools, Tools.
Integrated tools are available to easily view today's irrigation schedule,
perform "what if" analysis, and displays real-time status. These tools provide
immediate feedback showing the results in actual water savings or loss anytime
data base parameters are modified. The what-if analysis shows projected
water usage for all stations using the ADVANCED ET mode. A real-time root
monitor shows the actual percentage of moisture which remains in the root
zone at any instant in time.
Intelligence and Simplicity.
Although very comprehensive the system is extremely easy to use. Almost
all operation is reduced to a simple point and click of the mouse. All ADVANCED
ET input parameters have extensive context sensitive help. The system is
also designed to automatically inform the operator should any alarm conditions
occur. In the event that the user has inadvertently entered data which results
in operations which are incorrect, an alarm is automatically generated.
Examples of alarm notification conditions include:
-
Irrigation runtimes which
exceed a user specified water window.
Suggestions are provided to correct the problem.
-
Notification of stations with
insufficient moisture within their root zones
(burning up).
-
Station runtimes which are
too small.
