TUFLOW HR Output

Page Under Construction

Introduction

High Resolution (HR) Grid/Raster Map Outputs was first introduced in TUFLOW 2020-10-AB release. When an SGS model uses “SGS Approach == Method C”, the sampled elevations are retained at the end of the geometry processing. These sub-grid elevations include topography modifiers such as breaklines, and they allow a high-resolution elevation check file to be written and used for high resolution depth map outputs. Currently, ASC, FLT and TIF raster formats are supported.

Enable High Resolution Output

To produce high-resolution output, add “HRASC”, “HRFLT” or “HRTIF” to the “Map Output Format == ” command, for example:

Map Output Format == XMDF TIF HRTIF

At the moment, only water level and depth are supported as the High Resolution Output formats, i.e.:

HRTIF Map Output Data Types == h d

The map output data types and output interval can be defined separately for the High Resolution Output formats. For example:

Map Output Interval == 600 ! Sets all map output interval to 600 seconds

HRTIF Map Output Interval == 3600 ! Sets HR map output interval to 3600 seconds

The output resolution for high resolution grid output is defined using the following .tcf command:

HR Grid Output Cell Size == 0.5 ! m or ft

If this command is omitted, the default output resolution is set as the SGS sampling distance.
