Landscape characteristics influence the spatial pattern of soil water storage : Similarity over times and at depths

Auteur(s) et Affiliation(s)



Description :
The aim of this study was to examine the similarity in the spatial patterns of soil water storage (SWS) and its characteristic landscape positions for variable soil depths and over time at a field scale. Soil water content (further converted to SWS by multiplying with depth) was measured for 5 years (2007–2011) along a transect at a study site that has representative hummocky landscape of the North American Prairie Pothole region. It is highlighted that : 1) Similarity in the spatial patterns was scale and location dependent; 2) Persistent spatial patterns indicated consistent underlying control; 3) Macrotopography controlled consistent large-scale spatial patterns; 4) Landform elements yielded variable spatial patterns over time and at various depths.
