Objective:
The overall objective of this research project is to develop a prototype surface water object-oriented modeling system (SWOOMS) that will allow us to: (1) model and understand the ecological response of the Neuse River estuary (NRE) to varying nutrient (primarily N) loading; and (2) integrate this estuary model within a larger suite of models that can track nutrients from their source in the airshed and watershed to their ultimate arrival and impacts within the estuary. Existing estuarine water quality models have not been designed to be part of such a modeling suite and therefore may be poorly suited for linking with dynamic models of other environmental media. SWOOMS will be developed using object-oriented (OO) design and implementation, together with collaboration with researchers developing models in other media (i.e., the watershed, groundwater, and atmosphere) to yield an integrative environmental multimedia modeling system.Specific project objectives are to: (1) develop a finite-volume hydrodynamic and transport model component; (2) develop a water column biogeochemical model component; (3) develop a sediment diagenesis model component; (4) design and implement the model components using an OO framework; and (5) design and implement the OO surface water model for seamless input/output with OO models of the atmosphere, watershed, and groundwater media.
Progress Summary:
Future Activities:
In the next year, we will continue efforts to develop a prototype surface water object-oriented modeling system. Some specific activities are listed below.Development of a finite-volume hydrodynamic and transport model component. We will be testing the discontinuous Galerkin finite element technique further in the coming months prior to implementation in a fully three-dimensional code. Initially, we will be developing this in an "object-friendly" form of FORTRAN 90. In the coming months, this modified NEEM model will be converted to OO as described in item 4. In addition, we also will continue to develop a simplified, laterally averaged finite volume, hydrodynamics/water quality model using both procedure-based and OO paradigms.
Design and implementation of an OO surface water model for seamless input/output with OO models of the atmosphere, watershed, and groundwater media. We will continue to participate in discussions and workshops with multiple research groups and, as this or another model integration strategy becomes better defined, we will ensure that SWOOMS fits effectively within this system.
