Analytic Element Domain Boundary Conditions for Site-Scale Groundwater Flow Modeling Los Angeles Basin.

ABSTRACT: Physics-based groundwater flow modeling is a useful tool for the design and optimization of pump-and-treat systems for groundwater site cleanup. Numerical methods like finite differences and finite elements, and hybrid analytic elements, require boundary conditions (BC) to be assigned to the outer domain of the grid, mesh, or line elements. These outer BC do not always correspond with hydrogeologic features. Common practice in model setup is to either: (1) extend the model domain boundary outward such that introduced artificial outer BCs (e.g., first type head specified, second type flux specified) do not have undue influence on near-field scale simulations; or (2) assign outer BCs to capture the effective far-field influence (e.g., third type head-dependent flux).
