Abstract Interactions between surface and groundwater are a key component of the hydrologic budget on the watershed scale. Models that honor these interactions are commonly based on the conductance concept that presumes a distinct interface at the land surface, separating the surface from the subsurface domain. These types of models link the subsurface and surface domains via an exchange flux that depends upon the magnitude and direction of the hydraulic gradient across the interface and a… Expand

River networks and groundwater flow: a simultaneous solution of a coupled system
The proposed method is based on the idea of solving a single global matrix at once rather than solving separate matrices for each flow domain while improving the solution iteratively and provides a more efficient solution strategy for the coupled flow problem. Expand
