Accurate representation of urban blue-green infrastructure is required for continued implementation, and improvement. While monitoring data provides ground-truth information of these systems function, models can offer expected performance under a wider range of conditions. For larger blue-green infrastructure systems, like constructed stormwater wetlands (CSW), the hydraulics of flow through these systems is fundamental to the water quantity and quality treatment they can provide. Hydraulic models can supplement monitoring data to provide a holistic understanding of these systems. For two-dimensional hydraulic models, the terrain input dictates model accuracy. Different terrain models have various pros and cons with respect to the time and computational requirements for collecting and processing the data, the expense, the accuracy of representation of flow path and system storage, and the ease of use for ultimate use in a two-dimensional hydraulics. This work explores terrain models for input to a two-dimensional HEC-RAS model of a CSW.
