GIS and Hydraulic Models

The well-designed integration of a hydraulic model with GIS provides ready access to mission-critical data for water/wastewater professionals. As a result, risk-of-failure analysis, repair and replacement, capacity assessment, capital improvement planning, and numerous other water utility applications run more efficiently and more effectively.

Steps detailed in the book for a successful integration include the following:

• Establish a common vision, including data design, among stakeholders.

• Develop a standard methodology for assigning unique IDs to all utility assets.

• Reconcile GIS data to obtain a dataset suitable for ongoing hydraulic modeling.

• Define topology rules to ensure continued database integrity.

• Migrate corrected and added features and attributes from the hydraulic model to the GIS.

Esri's global water/wastewater industry manager Lori Armstrong edited Hydraulic Modelling and GIS, which was written in collaboration with the American Water Works Association, Water Environment Federation, and International Water Association. The book is recommended for water, wastewater, and storm water professionals, including engineers, managers, data managers and modelers, technicians, and water industry consultants.
