Fig. 3. Hydraulic conductivity (left) and water retention (right) functions for the peat soil as determined in the laboratory (3 replicates for each horizon) using inverse parameter estimation and direct methods. Open circles represent directly estimated hydraulic conductivities, squares are directly measured retention data, 
(h); solid lines represent inversely estimated K(h) and (h) functions; and dashed lines are (h) functions fitted to directly measured retention data and K(h) functions predicted from the fitted retention curves and the directly measured KS.
