Abstract: Various analytical and numerical solutions are available for the steady‐state form of Boussinesq's equation describing the phreatic surface on sloping lands. Except for the experimental results of Luthin and Guitjens (1967), ...

Abstract: The nonlinear Boussinesq unsteady-state differential equation used for evaluating drainage of sloping lands with drains lying at a distance above the impermeable layer was solved. A combination of explicit and implicit ...

Abstract: The problem of seepage from an unlined earthen canal is considered. The phreatic surface generated on the two sides of the canal is characterized by the nonlinear Boussinesq equation incorporating the slope element. A ...
