| Abstract: | The 4th Chivilcoy tertiary unit (1630 ha)receives irrigation water from theMontecaseros canal. This canal and its 16tertiary units is managed by theMontecaseros Users Association (8531 ha),being one of the 13 UA's in the Rio TunuyanMedio irrigation system (81200 ha). The 4thChivilcoy unit was selected for performanceresearch because it is representative for amajor part of the Tunuyan system; itcontains (near abandoned) fields with waterlogging and salinity problems and fieldswith maximum attainable yields. This paperreports on performance indicatorsquantifying the water delivery to the 12quaternary units. Also the delivery ofwater to the 19 farms in the Los Saucesquaternary unit (109 ha) is quantified. Allflow data were measured with broad-crestedweirs fitted with pressure loggersmeasuring the head at 15 minutes intervals.Because of this short interval, the timingof water delivery could be monitored andcompared with the intended deliveryschedule. |
