Modeling Flow and Transport in Drainage Areas with Shallow Ground Water
A new modified linked approach is introduced to solve the governing partial differential equations for subsurface flow and salt transport by finite difference. It combines the attractive features of the standard linked and continuous (composite) modeling approaches. The standard linked approach can...
