Any problems with interpreting the data or requests for further information should be addressed to Dr Andrew Western or Dr Rodger Grayson. ****************************************************************** Acknowledgments --------------- The Tarrawarra catchment is owned by the Cistercian Monks (Tarrawarra) who have provided free access to their land and willing cooperation throughout the project. Funding for this work was provided by: the Australian Research Council (project A39531077); the Cooperative Research Centre for Catchment Hydrology; Oesterreichische Nationalbank, Vienna (project 5309); the Department of Industry, Science and Technology, International Science and Technology Program; The University of Melbourne and The Ian Potter Foundation. The European Space Agency and the National Aeronautical and Space Agency provided SAR data free of charge. Assistance in the field and with data processing has been provided by Karen Moore. Field assistance has also been provided by Jenny Barkley, Alison Dedman, Judy Dunai, Sarah Ewing, Brian Finlayson, Myriam Ghali, Tim Green, Veronique Gomendy, Tony Ladson, Lee Heng, Natasha Heron, Neela Janakiramanan, Loic Mangeot, Tom McMahon, Graham Moore, Joorst Overbeek, Michael Roberts, Kate Smolenska, Hugh Turral, Mariska te Vaarwerk, Jeff Walker, Fred Watson, Garry Willgoose, Mark Wood, and Rodger Young. Garry Willgoose, Tom McMahon, Günter Blöschl, David Goodrich, Hugh Turral, and Brian Finlayson have provided useful suggestions on the field data collection. Veronique Gomendy and Hugh Turral assisted with interpretation of the soil cores. Graham Moore has provided help with instrumentation on the DCV. Fred Watson provided advice on GIS and data management. ------------------------------------------------------------------ Piezometer data --------------- 74 Piezometers measuring shallow water table depths are installed in the catchment. The file piezo.pos contains the coordinates of the piezometer data. These are installed to depths of between 0.5 and 1.1m depth. All piezometers extend below the boundary between the A and B horizons. Piezometers consist of 40 mm diamter slotted plastic pipe installed in 10 cm diameter auger holes. These are back filled with coarse gravel to within 10cm of the natural surface and a bentonite plug is added to prevent overland flow entering the piezometer directly. Water levels are manually read and are accurate to +/- 0.5cm. File: piezo.dat Format: One file contains all the piezometer data. It has a header plus 1 record for each measurement occasion. The record format is (with white space field separation): date(dd/mm/yyyy) time(hhmm) level1 level2 level3 ....level74 water levels are give as depths from natural surface (i.e. depth to water table) in units of cm. Where the tube is dry the water level is specified as “dry”. Tube depths are given in the header.
