AB: The analytic element method is well suited for modeling regional scale saturated groundwater flow. Recent advances enable the solution of models with tens of thousands of hydrogeologic features over scales of hundreds of kilometers. In order to implement such models, automated techniques are desired to translate regional scale conceptual models and/or readily available hydrologic base maps into model features. A suite of tools derived from standard cartographic generalization operators have been developed to perform these simplification tasks. Highly detailed digitized surface features (e.g. river and lake boundaries) are simplified into representative elements and strings of elements using algorithms designed to capture important geometric and physical properties. These simplified models are more computationally efficient and achieve similar (often nearly identical) results. In addition, a general framework for application of simplification operators to vector-based numerical models has been developed.
