This study aimed to describe the spatial variability of soil moisture in 8 hectares watershed from the Córdoba province, Argentina (31 °29' South, 64°13' West). Soil moisture was measured by gravimetry on 57 points at 3 different depths across 6 sampling dates. Geostatistic methods were used to describe spatial variability, and exponential semivariogram models without "nugget" effect were fitted. The models were cross validated. A clear spatial association between ranges of 70 and 145 m was observed.
