Algebraic technological function from a simulation model

Distributed parameter groundwater simulation models are difficult to couple explicitly with management models that seek to optimize an economic objective. For a groundwater system whose drawdown in response to pumping was modeled by a two‐dimensional linear partial differential equation, an algebraic technological function was produced that related seasonal pumping at wells in the system to drawdown at those wells. The algebraic technological function allowed an explicit coupling of the groundwater model with a quadratic programing management model.
