The Water Security Agency (WSA) is responsible for conveying water from Lake Diefenbaker via a series of reservoirs and canals to supply water for irrigation, municipal, industrial, recreational, and wildlife users located southeast of Saskatoon in Saskatchewan, Canada. In response to WSA’s recognition that a newer, more dynamic modeling platform was needed to better assist with long-term planning and short-term operational of this system, WSA commissioned Stantec Consulting Services and Precision Water Resources Engineering to develop a new modeling framework known as the Integrated Modeling System (IMS). The IMS consists of hydraulic models, three RiverWare models (Long-Term Planning Model, Annual Operations Model, and Short-Term Operations Model), an underlying database, and a data management interface to allow connections between the user and all components of the IMS.
This presentation will provide an overview of WSA’s system and the development of the WSA IMS. This presentation will focus largely on the RiverWare models embedded within the IMS, including how (1) they were utilized to represent WSA’s system, (2) key operations in the system were represented within RPL logic, and (3) RiverWare functions to allow WSA to answer key questions about their current and projected future water supply system operations and infrastructure.
