Résumé :
|
The soil water retention curve (WRC) may be estimated from soil texture if there is shape similarity between the normalised cumulative particle mass size distribution curve (PSD) and the WRC. For similar shaped curves, parameters describing the shape of the PSD may also describe the shape of the corresponding WRC. We studied the relation between PSDs and WRCs at 4 sites in Western Australia with predominantly sandy soils and fitted a sigmoidal function to all normalised PSDs and WRCs.
