Abstract

Landscape irrigation systems serve the purpose of lifeline for urban agriculture and horticulture activities such as golf courses, theme parks, airport turfing, traffic islands, surface and rooftop gardening in commercial complexes. A Landscape irrigation system is essentially a pressure irrigation system comprising pop up sprinklers, micro sprinklers and hydrants. The hydraulics involved is very complex due to undulating nature of landscapes. The performance of the pop-up sprinkler used in irrigation of landscaping project (University Auditorium, TNAU) was evaluated. The main analysis examined the relationship between flow-pressure, profile of distribution of water and Christiansen's Uniformity Coefficient (CUC) related with flow pressure. The value of CUC was observed more than 94 percent.

Keywords: Landscape development, Pop-up sprinklers- Friction loss, Uniformity Co-efficient.
