Abstract

Practical, automatic real-time control of surface
irrigation faces several difficult constraints. Most surface
irrigation water supplies must be scheduled in advance and use
must be coordinated with other demands. Either the supply
system must he able to adapt to the occasional demand of
automatic systems, or the application systems must communicate
their needs to the supply system with the required lead time.
Surface irrigation performance depends strongly on soil
surface and infiltration characteristics. These parameters
normally vary widely spatially and from irrigation-to-irrigation,
and are difficult to predict. Performance
monitoring and system adjustment is usually required to insure
good performance, especially during early-season irrigations.
Automatic real-time control systems thus must include some type
of performance feed-back control. This paper discusses the
severity of these constraints and possible solutions for the
several types of surface irrigation systems and water supply
conditions.
