Estimating canopy ecohydrological parameters of a Picea abies stand in the Caspian forests, North of Iran
The aim of this research was to estimate the ecohydological parameters of the canopy covers including estimated canopy saturation point (P´G Estimated), canopy storage capacity (S), the ratio of mean evaporation rate from the wet canopy to the mean rainfall intensity ( ), free throughfall coefficien...
