Description :
The aims of this study were to examine time stability of the spatial pattern of soil water storage (SWS) at different seasons and depths, to identify representative monitoring locations (RMLs) that consistently reflect field average SWS, and to recommend efficient ways to identify these locations. Soil water was measured down to vertical depth intervals using time domain reflectometry and neutron backscattering along a hummocky transect in semiarid central Canada. It is shown that similarities in the spatial patterns were depth dependent, and that persistent spatial patterns indicated consistent underlying hydrological controls. The locations that store about field-averaged soil water were identified at depths. The measurement of SWS through representative monitoring location(s) may be used for environmental monitoring and modelling, irrigation scheduling, nutrient recommendations, and predicting greenhouse gas emissions.
