397198 - WaterPaths: a new open source stochastic urban water portfolio simulation framework

Thursday, June 7
8:30 AM - 10:00 AM
Location: Greenway GH

The growing access to, and reduced cost of, computing power in recent years has promoted rapid development and application of advanced stochastic simulation frameworks. This work introduces the WaterPaths model: an open source simulation framework designed to simulate stochastic risk and demand-based sequencing of long-term regional water infrastructure investments while simultaneously considering key short term operational decisions (e.g., use restrictions, transfers, financial instruments, etc), bridging the gap between weekly management and yearly planning decision making for water utility companies. WaterPaths’ code is designed to be easily expandable to allow researchers in the field of water resources systems to implement and test new conservation and financial mitigation strategies, such as schemes for allocating water transfers among regional utilities and different ways of structuring drought insurance policies. Besides being used to advance new portfolio planning innovations, the framework can also be used as a benchmark regional planning problem for testing new robustness frameworks and optimization algorithms, as well as to get insights on particular systems of interest. The code, written in C++, is capable of multi-platform parallelization strategies (i.e., personal computers, cloud, or large clusters) enabling scalable ensemble-based exploratory analyses. We introduce the WaterPaths simulation framework for a hypothetical case study in which a group of fictitious water utilities seek to collectively balance the use of water use restrictions and transfers and infrastructure construction against their inherent financial risks, mitigated by the use contingency funds and index insurance policies.
