This short communication describes the use and comparison of three methods used to calculate the flow discharge from tidal wetland streams. The techniques presented are (a) bottom‐mounted ADCP deployments, (b) vessel‐mounted ADCP transects, and (c) a volume inundation spatial model that relies on a high‐resolution LiDAR dataset and time‐series of water surface elevation data. The relative agreement between these three methods is used to build confidence in the application of these techniques to the challenge of deducing discharge from tidal wetlands.
