The Peak Flow Surface tool will attempt to create a surface of the flow that each cell (grid only) in a model contributes to. It is designed to run using the model time series results (level, X and Y-velocity). For each cell, the tool will walk laterally perpendicular to the velocity vectors until a dry boundary is reached. This line is then used to calculate the flow.
Results can be "patchy", depending on the conformity of the surface, and should be used a guide to the flow in an area. Specific flow at any location should be calculated using the flux plot tool.
