Shape Parameters
The shape of water retention curves can be characterized by several models, one of them known as the van Genuchten model:
where
- is the water retention curve ;
- is suction pressure ( or cm of water);
- saturated water content ;
- residual water content ;
- is related to the inverse of the air entry suction, (, or cm−1); and,
- is a measure of the pore-size distribution, (dimensionless).
Based on this parametrization a prediction model for the shape of the unsaturated hydraulic conductivity - saturation - pressure relationship was developed.
