ABSTRACT:
The Urban Water Infrastructure Investment Model (UWIIM) is a discrete time dynamical systems model designed to reflect the general flow of water, investment, and information in a stylized urban water coupled infrastructure system. The model couples operational considerations regarding the use of infrastructure, including storage, processing, and delivery infrastructure to meet annual demand given varying, user-defined, hydrologic inflows with political-economic considerations at play in three annual decisions: short-term (with a year) curtailment of demand, investment in infrastructure, and rate-setting. We demonstrate the model with representative configurations for three Phoenix Metropolitan Area (PMA) cities: Phoenix, Scottsdale, and Queen Creek. A detailed description of the model can be found in the attached Supporting Information document. The model uses the Julia programming language (version 1.8.4).
The resources published here allow users to (i.) run the UWIIM for each of the three PMA cities and vary the parameters or initial conditions used and (ii.) replicate the sensitivity analysis performed in the referenced manuscript. Both tasks can be performed with the Jupyter notebooks or Julia code contained in the source code file. We also provide the raw outputs from the sensitivity analysis and R scripts used to produce the analysis figures displayed in the manuscript.
