The use of conventional water resources for golf course activities is increasingly contested. As a result, in recent years there has been a considerable demand for golf courses to adopt environmentally sustainable strategies. Moreover, other exploitation-derived resources of turfgrass treatment have important economic costs. Thus, a major optimisation in resources and time is required, which is covered by the WATERGOLF project through different modules. This paper presents an intelligent system to optimise water consumption in golf courses, as well as to improve their management. Hence, the system is designed to suggest corrective actions through an expert system to the greenkeeper, as well as to trigger alarms in risky situations in four different modules: irrigation, weeds, diseases, and fertility. These suggestions are based on expert knowledge acquired from turfgrass experts and a set of measurements gathered by advanced sensors placed in the golf course. Although the intelligent system is currently being developed, it is expected that a further evaluation in real conditions will help golf facilities to reduce their maintenance costs and environmental impact.
