Description:
Environmental computer models are usually desktop models. Some web-enabled models are beginning to appear where the user can use a browser to run the models on a central web server. Several issues arise when a desktop model is transferred to a web architecture. This paper discusses the issues encountered and the solutions implemented in web-enabling the BLTM (Branched Lagrangian Transport Model) software. The benefits of a web architecture for environmental modeling are discussed along with the drawbacks. The paper also presents the results of a web-based simulation of a fertilizer solution spill on the Ohio River.
The BLTM software has been developed for transport modeling applications in systems of one-dimensional channels. It divides the waterbody into branches and solves the advective dispersion equation by using a Lagrangian reference frame. This computational scheme compares favorably with the Eulerian solution technique used in the WASP (Water quality Analysis Simulation Program) model developed by USEPA. This paper discusses how the BLTM model was inserted to create the new functionality. Common-off-the-shelf software was used for rest of the components in the web architecture.
