Incorporating new locations into a hydrodynamic model using ArcGIS Pro

Abstract

ALGE3D is a 3-D hydrodynamic model developed at the Savannah River National Laboratory to predict pollutant dispersion. The model has several predefined locations incorporated, however adding new locations into ALGE3D is manually intensive and time-consuming. In the event of an emergency, ALGE3D can only be used if an event occurs at one of the predefined locations incorporated into the GUI. This project focuses on streamlining the integration of new locations into ALGE3D by utilizing tools in ArcGIS Pro. The Stream Order tool was used to delineate streams and assign them an order, using the Strahler method, versus manually defining these streams in Microsoft Excel. This work advances development to turn ALGE3D into a product for emergency response use by allowing the user to incorporate a new location into ALGE3D quickly, should an event occur at a location that is not already predefined.
