melt.darcyscheme(self, iii)

Threshold thickness for ice lenses to be impermeable Approach: modify density for calculation of Darcy variables (upper threshold set to 910) Liquid water input is distributed in upper nodes rather than using a flux boundary condition at the surface node (causes high runoff) Input is accomodated until impermeable node reached: remaining input runs off Melting and refreezing occur at each Darcy step
