|Abstract: ||The presented Model of Irrigation Management
was designed for application on
green spaces and leisure areas.
The Model recognizes water as a production
key-factor and optimizes its use on the
irrigation of green spaces, giving particular
attention to the temporal and spatial variation
of input variables.
Variables entered in the Model included
existing or future target plant species,
phenological phases, type of soil (i.e. location
and physical characteristics), topography
and climate factors.
Model construction was similar to the
methods outlined in FAO Report 56,
namely: the method of Penman-Monteith
for the calculation of reference evapotranspiration,
the use of dual cultural coefficients
to obtain cultural evapotranspirationand the opportunity of irrigation according
to the hydric balance.
The Model integrates the programming of
algorithms implemented in Visual Basic 6,
VB6 and a Geographic Information System
The Model provides the irrigation parameters
in real-time scale, the timings for
irrigation, depth per irrigation, the period of
irrigation, time between two irrigation episodes,
and for the sprinkle irrigation, the
mean application rate and the degree of pulverization.
The Model is used in association with an
automatic weather station and irrigation system.|
