Highlights
GISRed is a customized extension to ArcView® GIS3.2, oriented to modeling and calibration of water distribution networks, and which integrates all capabilities of the widely-used hydraulic modeling software EPANET 2.0
More advanced modules to carry out complex tasks such as topological analysis, demand allocation and elevation interpolation tools, have been developed to enhance the features offered by the EPANET 2.0 interface and the inner capabilities of the supporting GIS platform
GISRed has been developed as an extension to ESRI’s ArcView GIS3.2 software that integrates the widely-used hydraulic modeling software EPANET2.0 along with all the original GIS functions of ArcView. This ‘built-in’ application was originally conceived to fulfill the drawbacks of the EPANET2.0 GUI in treating different sources of data such as CAD or shape files, in assigning some properties to the model components such as demands and elevations, in calibrating the network parameters to match the results with the field measurements, and in contrasting the results of different scenarios between them or against the background information
Summary
The first step prior to developing a master plan is to build a network model. Typical steps for a modeler when using the GISRed Extension to build a water distribution model are: 1. Create the layout of the distribution network system either using the editing tools or importing spatial data from a CAD file, a shapefile or Epanet input file. 8. Run a hydraulic/water quality analysis and view the results of the analysis. 9. Adjust some parameters of the network manually as a first approach, to match results with expected values. Send the calibration results back to the model. Perform a new simulation and analyze the results again. If the results are good enough, stop the process, otherwise, proceed with the calibration
