- saturated permeability (
k_sat
) from cm/day to m/s, particle size from µm to mm - pressure head (
preshead
) from cm_H2O to kPa.
- correlation heatmap soil properties et autre variables.
- Plots porosity vs. permeability
- Plots all particle size distributions (GSD) et water retention curves (WRC).
- Focuses on sands filtering soil texture ("sand") avec vis ge GSD and WRC.
- Interpolates GSD curves select code et interpoler particle_size (cumulative percentages for 7 values), assurer consistence de comparasion.
- water retention curves :
preshead
(pressure head) andtheta
(volumetric water content) bulk_density
(rho) influence on soil structure and water retention capacity.- Porosity et permeability 'k_sat' are selected by teacher
- GSD is made by particle_size and fraction size.
