Abstract:

This technical note describes an approach for incorporating population dynamics into ecosystem-level assessments. The toot described herein is termed the Coupled Eulerian- Lagrangian CEL Hybrid Ecological Model. The CEL Hybrid Ecological Model couples the kinds of models typically used by engineers the Eulerian module with the types of models typically used by biologists the Lagrangian module. The CEL Hybrid Ecological Model can be applied singly or in concert with other tools and methods that describe the physical environment and hydro biogeochemical processes having ecosystem significance.
