Estimation of a network irrigation efficiency to cope with reduced water supply
Abstract The overall irrigation efficiency, $ e_{p} $, for the irrigationnetworks in the Thessaloniki plain, in Northern Greece, wasestimated from historical data, spanning eight years. Irrigationnetworks differ regarding the method of water delivery and themethod of field application. Overall irrigation efficiency is theparameter which helps to adjust water supply to meet the actualcrop water requirements. A method is introduced which calculatesnetworks $ e_{p} $ using spatially distributed data. Efficiencyvalues for all systems were calculated using the proposed method.Seasonally averaged $ e_{p} $ values for eight years for 32(surface and sprinkler) irrigation networks ranged from 0.38 to0.81. Analysis of the time series $ e_{p} $ values can identifyoperational factors that might affect network $ e_{p} $. Sprinklerand surface network irrigation efficiencies did not show anysignificant difference.
