Using the design characteristics of the Biosphere 2 hillslope experiment, this study investigates aspects of soil moisture spatial and temporal variability in a zero‐order catchment of a semiarid climate. The hydrological response of the domain exhibits a particular structure, which depends on whether topography‐induced subsurface stormflow is triggered. The occurrence of the latter is conditioned by topography, soil depth, and pre‐storm spatial distribution of moisture. As a result, a non‐unique behavior of soil moisture spatial heterogeneity emerges, manifested through a hysteretic dependence of variability metrics on mean water content. Further, it is argued that vegetation dynamics impose a “homogenizing” effect on pre‐storm moisture states, decreasing the likelihood that a rainfall event will result in topographic redistribution of soil water. Consequently, post‐rainfall soil moisture dynamics associated with the effect of topography that could lead to the enhancement of spatial heterogeneity are suppressed; a potential “attractor” of catchment states emerges. The study thus proposes several hypotheses that will be testable within the framework of long‐term hillslope experiments.</jats:p>"}],"type":"journal_article","quality_controlled":"1","_id":"22446","article_processing_charge":"No","OA_type":"free access","article_number":"W09521","date_published":"2010-09-01T00:00:00Z","date_updated":"2026-07-30T05:53:53Z","oa_version":"Published Version","author":[{"full_name":"Ivanov, Valeriy Y.","last_name":"Ivanov","first_name":"Valeriy Y."},{"id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","last_name":"Fatichi","full_name":"Fatichi, Simone","first_name":"Simone"},{"first_name":"G.
