Received for publication May 21, 2001. Surface contamination by bomb-derived and Chernobyl-derived ¹³⁷Cs has been subject to changes due to physical decay and lateral transport of contaminated soil particles, which have resulted in an ongoing transfer of radionuclides from terrestrial ecosystems to surface water, river bed sediments, and flood plains. Knowledge of the different sources of spatial variation of ¹³⁷Cs is particularly essential for estimating ¹³⁷Cs transfer to fluvial systems and for successfully applying ¹³⁷Cs as an environmental tracer in soil erosion studies. This study combined a straightforward sediment redistribution model and geostatistical interpolation of point samples of ¹³⁷Cs activities in soil to distinguish the effects of sediment erosion and deposition from other sources of variation in ¹³⁷Cs in the small Mochovce catchment in Slovakia. These other sources of variation could then be interpreted. Besides erosion and deposition processes, the initial pattern of ¹³⁷Cs deposition, floodplain sedimentation, and short-range spatial variation were identified as the major sources of spatial variation of the ¹³⁷Cs inventory.
