| Zusammenfassung |
| Current challenges in natural resource management have created demand for
integrated, flexible, and easily parameterized hydrologic models. Most of
these monolithic models are not modular, thus modifications (e.g., changes in
process representation) require considerable time, effort, and expense. In
this paper, the feasibility and challenges of using the Object Modeling
System (OMS) for natural resource model development will be explored. The OMS
is a Java-based modeling framework that facilitates simulation model
development, evaluation, and deployment. In general, the OMS consists of a
library of science, control, and database modules and a means to assemble the
selected modules into an application-specific modeling package. The framework
is supported by data dictionary, data retrieval, GIS, graphical
visualization, and statistical analysis utility modules. Specific features of
the OMS that will be discussed include: 1) how to reduce duplication of
effort in natural resource modeling; 2) how to make natural resource models
easier to build, apply, and evaluate; 3) how to facilitate long-term
maintainability of existing and new natural resource models; and 4) how to
improve the quality of natural resource model code and ensure credibility of
model implementations. Examples of integrating a simple water balance model
and a large monolithic model into the OMS will be presented. |
