A Stategy for Web-based Modeling of Hydrodynamic Processes

Hydrodynamic model generally deals with enormous amount of data and utilizes huge computational resources for simulation. Powerful and robust servers with extensive storage capabilities are therefore desirable for rapid simulation. Unfortunately, it is not always possible for an individual to effort those kind of facilities whereas a central computer system can be the viable alternative to serve many clients. The simplest way for a client to communicate with the central simulation server can be using a web browser and such kind of simulation has been classified as web based simulation. In this paper, simulation of a hydrodynamic model has been investigated as a case study of the large scale application of web based simulation. Standardized description of the hydrodynamic model data or, metadata has been created using geographical information metadata, ISO 19115:2003 standard. A formal specification of the simulation domain or ontology has been developed to share and retrieve this information unambiguously. Ontology based simulation can also be applied for analyze and future reuse of the simulation domain knowledge. Therefore, web based simulation of hydrodynamic models could be a new paradigm shift in the hydrodynamic modeling as well as numerical modeling area.
