THE TARRAWARRA DATA SET - SOIL-MOISTURE PATTERNS, SOIL CHARACTERISTICS, AND HYDROLOGICAL FLUX MEASUREMENTS

Experiments investigating the spatial variability of soil moisture con ducted in the 10.5 ha Tarrawarra catchment, southeastern Australia, ar e described. The resulting data include high-resolution soil moisture maps (over 10,000 point measurements at up to 2060 sites), information from 125 soil cores, over 1000 soil moisture profiles from 20 sites, 2500 water level measurements from 74 piezometers, surface roughness a nd vegetation measurements, meteorological and hydrological flux measu rements, and topographic survey data. These experiments required a maj or commitment of resources including 250 person days in the field, wit h a further 100 person days in the laboratory preparing for field trip s and checking and collating data. These data are available on the Wor ld Wide Web (http://www.civag.unimelb.edu.au/data/).
