Co-Themes: Water Resource Modeling
Mathematical models representing different hydrologic, hydraulic, and water quality elements of the human-environment system are important decision-support tools that can be employed to quantitatively evaluate NbS Design alternatives, provide forecasting and real-time analysis of flood risk, and help to understand system performance as part of a Monitoring and Assessment program. We employ a conceptual, deterministic modeling approach that typically uses the PCSWMM model (1d or 2d) (https://www.chiwater.com/Home) either as a standalone or coupled with 3d coastal or reservoir models such as DELFT3d (https://oss.deltares.nl/web/delft3d) and ELCOM-CAEDYM (https://www.hydronumerics.com.au/software/aquatic-ecosystem-model-3d). PCSWMM incorporates a modern, powerful GIS engine that works seamlessly with the latest GIS data formats and as such can scale up (large watershed scale investigations of water quantity, quality, and NbS system interventions) or down (e.g. NbS site design) within the same modeling framework. In support of NbS Design PCSWMM also interfaces with BIM software such as CIVIL3d and Sketchup to better integrate design, performance assessment, and monitoring of NbS landscape features.
