  text: <jats:p>By partitioning mass and energy fluxes, soil moisture exerts a fundamental
    control on basin hydrological response. 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>
