The great target for mankind is always to achieve the optimum use of available resources against
the increasing food and other demands of the world population versus the shrinking resources.
This paper provides snapshots of research and practical implementation of optimum design
concepts and criteria of pressurized irrigation systems. Technical papers, reports and case studies
are reviewed addressing revision approach for the optimum design of pressurized irrigation
systems. The definition of the optimum irrigation has to be as widely as maximization of overall
benefits including nonmonetary benefits; such as water quality protection and food security.
Reliable information on irrigation methods is important for determining agricultural water demand
trends. The model HYDRUS-2D can be employed to derive characteristic irrigation control
functions to determine optimal irrigation times and water amounts. Also, a software application for
Android mobile devices is available to evaluate the responsiveness of all available optimum
commercial diameters to operational changes.
The optimization of the irrigation system is an important factor to enhance water use efficiency. To
get optimum pressurized irrigation systems, the common employed optimization techniques are
linear programming, recursive design and genetic algorithm.
