Models play an important role in river basin management and different softwares have been developed to quantify the impact of land management practices on river basins, to solve water allocation problem, to predict extreme events (drought and flooding) and many other applications. Soil and Water Assessment Tool (SWAT) is one of these software used in water management practice. The software is used worldwide and there are more than 1000 peer reviewed articles published. Reviews of these papers show that there is much duplication of SWAT applications for the same case study. One of the reasons is the lack of information, documentation of existing models, or lack of access to these model applications. Since the development of a model is very time consuming and demand financial resource, a platform for sharing model applications will be very useful tool for sharing and collaborating in developing application models for a particular catchment. The important component of this platform (spatial data service) is the metadata catalog where metadata (in this case information about the application models) is stored and users can search for application model of their interest, review detail information provided in the metadata which include (title, purpose, abstract, dataset used, calibration process etc...), and retrieve the application model via a link provided in the metadata. In the metadata of the model applications, links are made to the metadata of the data as well as the metadata of the model codes that were used for the models. Additional information when available is provided to enable the reproducibility of the model and allow for an evaluation of the model reliability.
