Management of water systems often requires the integration of data and models across a range of sources and disciplinary expertise. Service-Oriented Architectures (SOA) have emerged as a powerful paradigm for providing this integration. Including models within a SOA presents challenges because services are not well suited for applications that require state management and large data transfers. Despite these challenges, thoughtful inclusion of models as resources within a SOA could have distinct advantages that center on the idea of abstracting complex computer hardware and software from service consumers while, at the same time, providing powerful resources to client applications. With these advantages and challenges of using models within SOA in mind, this work explores the potential of a modeling service standard as a means for integrating models as resources within SOA. Specifically, we investigate the use of the Open Geospatial Consortium (OGC) Web Processing Service (WPS) standard for exposing models as web services. Through extension of a Python-based implementation of WPS (called pyWPS), we present a demonstration of the methodology through a case study involving a storm event that floods roads and disrupts travel in Columbia, SC. The case study highlights the benefit of an urban infrastructure system with its various subsystems (stormwater, transportation, and structures) interacting and exchanging data seamlessly.
