WMS:Compute Flow Directions and Flow Accumulations

Overview

HY8 Modeling Wizard showing the Compute Flow Directions and Flow Accumulations step

The Compute Flow Directions and Flow Accumulations step is used for running TOPAZ to compute flow directions and accumulations.

Help

Compute TOPAZ flow data and... – You can choose either to write your TOPAZ output to a specific directory or to the temp directory. Most frequently, you will just write your TOPAZ output to a temp directory.

Units – Use the units combo boxes to define your model's computation units.

Compute Topaz – This button runs TOPAZ using the settings you have selected.
