MIRRIG: sistema de apoio à decisão para microrrega. Aplicação aos espaços verdes

Abstract

MIRRIG is a decision support system (DSS), developed to design and evaluation of microirrigation system under operation. This DSS comprise a database and the models: design and evaluation. The database contains information on emitters, pipes, soils, as well as plants and the systems under design. Design models allow creating and comparing a set of design alternatives based upon an integration of technical, economic and environmental criteria, and may be useful to maximize the beneficial use of water for irrigation of golf courses and public landscape areas. The evaluation component is a tool to advise decision maker about how to improve their microirrigation systems when using data obtained during field evaluation of systems under operation. This article describes the DSS MIRRIG and presents the results of its application in two different landscapes in Portugal (Esposende and Faro)
