The objective of this study was to characterize the structure and the spatial dependence magnitude of geobiophysical variables in the springs of the Ribeirão Santa Cruz stream watershed, Lavras, MG, using geostatistical interpolation methods. Ordinary kriging system and inverse power distance (IPD) interpolation methods were used to map the altitude, flow, areas of recharge and vegetation of 175 perennial springs in an area of 86.99 km². Better peformance was observed with estimation using the kriging method as compared to the IPD method.
