Solutions of Boussinesq Equation in Semiinfinite Flow Region
Publisher: American Society of Civil Engineers
Abstract: In a semiinfinite flow region, prediction of the water table profile due to an abrupt rise or drop in the canal or drain water level in the cases of recharging and discharging aquifers has been done for times equal to 1.0, ...
Interaction of Stream and Sloping Aquifer Receiving Constant Recharge
Publisher: American Society of Civil Engineers
Abstract: An analytical solution and finite-element numerical solution of a linearized and nonlinear Boussinesq equation, respectively, were obtained to describe water table variation in a semi-infinite sloping/horizontal aquifer ...
Falling Water Tables in Horizontal/Sloping Aquifer
Publisher: American Society of Civil Engineers
Abstract: To describe falling water tables between two drains lying on a horizontal/sloping impermeable barrier, analytical solutions of the Boussinesq equation linearized by Baumann's and Werner's methods and numerical solutions ...
Water Table Rise in Sloping Aquifer due to Canal Seepage and Constant Recharge
Publisher: American Society of Civil Engineers
Abstract: Analytical solutions of the linearized Boussinesq equation and a fully implicit finite-difference numerical solution of the nonlinear Boussinesq equation were obtained to study transient and steady-state water table rise ...
Drainage of Sloping Lands with Constant Replenishment
Publisher: American Society of Civil Engineers
Abstract: An analytical solution is derived using the Boussinesq equation to describe an unsteady rising water‐table profile in an aquifer lying over a mildly sloping impervious bed in response to constant replenishment. A Hele‐Shaw ...

Finite Difference Solution of Boussinesq Unsteady‐State Equation for Highly Sloping Lands
Publisher: American Society of Civil Engineers
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), ...
Transient Drainage to Partially Penetrating Drains in Sloping Aquifers
Publisher: American Society of Civil Engineers
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 ...
