Objective:
Project: Extending the capabilities of EPANET user interface with plugin tools.
Extending the capabilities of EPANET user interface with plugin tools. Simulation of water distribution systems is crucial for the planning, management, operations, and control of municipal water systems. EPANET has been extensively used in a range of design, operation, and management problems that require hydraulic and water quality simulations. Multiple demand conditions, planning scenarios, and various computational methods for integrating with external data sources and programming tools are common challenges to water community that are not directly addressed in the current EPANET software. The US EPA has recently focused on developing an open source modular and extensible user interface, which allows plug-in and scripting support, such that new applications can be integrated and shared within the EPANET environment. In this study, we develop and test the new plugin environment compatible with the new EPANET user interface (UI).
Project: Exploring the Operational Effects of Gentrification on Water Networks
Gentrification can have a negative impact on the operation of the water network -- unless operational adjustments are made corresponding to changing human-infrastructure interactions. A pump upgrade, if existing pumps working at full capacity, would be required. Utilities, which often anticipate changes in the network due to total population increases, would also benefit from an assessment of human-infrastructure interactions such as that occur with gentrification
Project: On-line implementation of models for training
Develop and deploy a software-as-a-service implementation of EPANET/SWMM for on-line access and running of the codes for training purposes.
Project: Improved hydraulic network solver for SWMM
Develop and automated calibration tool for SWMM
Project: Outreach to the SWMM and EPANET communities
Build the foundations for a sustainable community of model developers and users
Project: Community web portal and model repository
Develop a web-centered community for SWMM and EPANET
Progress Summary:
Extending the capabilities of EPANET user interface with plugin tools.
To test the new plugin environment of EPANET UI, two plugins were developed in Python scripting language: (1) optimal network design using genetic algorithms and (2) integration of the Water Network Tool for Resilience (WNTR) developed by Sandia National Labs for pressure driven analysis. The EPANET user can add the new plugins to the main EPANET UI screen and select to solve the optimal design problem using genetic algorithms optimization approach. additionally, the user can choose to perform the default demand-driven hydraulic simulation currently implemented in EPANET or choose to perform the pressure-driven hydraulic simulation, which is offered by the WNTR simulation toolkit.

On-line implementation of models for training
a 3rd party application layer to get EPANET and SWMM to run on an ARM7 machine. This activity is exploratory work to allow for a NCIMM built/managed data center to serve worling instances of EPANET/SWMM with the GUI intact using VNCserver. Works as proof of principal, but certain graphics elements cause the implementation to crash. We suspect the cause is limitation in the application layer -- the company that sold the application layer is out of business. RealVNC (a different 3rd party) was the service used to broker the VNC connections -- this worked quite well, and their annual enterprise fee is reasonable. Pursuant to the objective, we built several web-based interfaces as experiments to explore the software-as-a-service goal to support the training mission. All these worked, but still take too much user knowledge to implement routinely. The main value of these exercises was to develop meaningful ways to handle the required file systems for different users.
Review of WDSA water security
This research completed a comprehensive review of modeling and methodological techniques that have been developed to enhance water distribution security in collaboration with leaders in this field. The review groups studies based on their contribution to management of contamination threats, physical threats, interconnected infrastructure threats, and cybernetic threats. Modeling studies are mapped to five emergency management activities, including risk assessment, mitigation, emergency preparedness, response, and recovery.
Improved hydraulic network solver for SWMM
A genetic algorithm was developed to provide automated calibration of SWMM. The routine first represents the catchment network as a directed graph object using the NetworkX python package for flexibility in handling real-world observed data availability. Once the calibratable subset of the system is identified, a multi-objective, genetic algorithm (modified Non-dominated Sorting Genetic Algorithm II: NSGA-II) estimates the Pareto front for the objective functions within the feasible performance space.
Outreach to the SWMM and EPANET communities
The Center sponsored two community forums (EPANET and SWMM) to obtain feedback from the community on issues and priorities in the development of improvements to the models. In addition, we have conducted training sessions for the models through the our collaboration with the Urban Watersheds Research Institute (UWRI).
Community web portal and model repository
Prototype development is underway for of NCIMM website and community user portal to support software and training for SWMM and EPANET models. We are developing a cyber-infrastructure back-end to allow model sharing and analyses.
Future Activities:
Extending the capabilities of EPANET user interface with plugin tools
We are continuing to develop better hydraulic models for simulating hydraulic and quality conditions in water distribution systems.
Exploring the Operational Effects of Gentrification on Water Networks
None
On-line implementation of models for training
The exercise to repeat the experiment on native x86-64 architecture is underway. If the fault that occured in the ARM7 machines vanishes, then will expand this service and prepare a demonstration site for limited users (~25 concurrent connections) at a future training camp.Complete the x86-64 experiments. Assuming sucessful, obtain a small collection of x86-64 SBC to build a small data center and a RealVNC enterprise service. Write a user manual for remote users to use the service. Arrange to spend a small portion of a training class to demonstrate and test the system with trainees.

Manuscript to be submitted to Journal of Environmental Engineering
Improved hydraulic network solver for SWMM
The new derivation is being used to test a new form of discrete model (manuscript in development) and adapt the method to a Fortran 2008 coarray code for parallelization.
Outreach to the SWMM and EPANET communities
We will continue to develop community relationships to build sustainable open-source collaborations for the future of SWMM and EPANET.
