Project Description

This is an Arcgis Add-in tool that implements a hydrological model -- TOPMODEL. This was developed by using c#, ArcObjects API for .Net and wateroneflow hydrologic data web service.

There are two modules in this tool. One is data download module and the other one is topmodel module.

For the data used in this hydrological model, I used the Hydrological Information System WaterOneFlow web service to download the precipitation data, discharge data and evapotranspiration data.

For the topmodel module, statistical software R is embedded in C#. By using existing R packages,  hydrological data is preprocessed and passed to TOPMODEL.
