The Water Network Analysis Model (WaterNAM™) is a geospatial hydraulic model for analysis and design of water distribution systems. It performs both steady state and extended period simulation of water flow and quality, including constituent concentrations and fire-flow analyses, and energy-cost assessment. WaterNAM utilizes U.S. Environmental Protection Agency's EPANET software (version 2) as the simulation engine and ESRI's ArcGIS® for spatial data development, providing a robust platform for engineers to design, analyze and optimize different components of a water distribution network. The extension allows users to efficiently set up a model and perform hydraulic and water quality simulation entirely within the ArcGIS® system.
WaterNAM can be applied to
For hydraulic and water quality modeling of distribution networks, EPANET is referred as the fundamental program, and it's one of the most widely used applications in this sector. However, there are a number of advanced commercial packages available also like WaterCAD, InfoWater, KYPipe etc. Each of them have their own classified features for the modelers. In this aspect, WaterNAM joins the market with its unique credibility by bringing a geospatial environment in ArcGIS® platform for the EPANET software, and obviously with reduced amount of cost and modeling effort for the users (compared to other applications).
Any experienced modeler would agree with the fact that preparing input data for a sophisticated model takes the lion's share of his/her total modeling time. Besides, the data processing for a large distribution model often becomes monotonous and complex simultaneously. By integrating EPANET within ArcMap™, WaterNAM helps users to significantly reduce the time it takes to prepare model input, makes data processing almost automated, increase the accuracy of input data, store and manage data in a database environment and visualize and inspect model objects on a map. It allows users to run simulation and view output without ever exiting the GIS environment.
