Scenario Management

This is a core feature designed for master planning and managing capital improvement programs over multiple time horizons. Using a hierarchical scenario tree, users can build out and compare distinct future planning scenarios for 5, 10, or 20 years out. Each scenario can represent a different combination of capital works, system growth, and changes in network demand, providing a structured way to evaluate long-term strategies and investments.

This feature allows users to define which network elements are included in a given scenario's simulation. Users can enable or disable parts of the network, such as a future subdivision or a main taken out of service for maintenance. When a simulation is run, only the elements in the active topology are sent to the EPANET engine, providing an efficient way to manage different network configurations. In addition to manual selection, users will also be able to define the active facility set using queries or rules (e.g., activate all pipes with an installation year before 2025), enabling dynamic and automated management of complex scenarios.

To help users interpret the results of their analyses, this tool will provide a direct comparison of results between any two or more scenarios. The differences in key outputs like pressure, flow, and water age will be highlighted in both tabular and graphical formats, making it easy to understand the impact of the changes made in each scenario.
