TUFLOW Message
ERROR 3025 - Roughness height must be >= 0.
Alternate Message
NA
Message Type
ERROR
Description
Materials may use either fixed mannings, depth-varying mannings, or log-law roughness formulations for bed resistance.
To utilise fixed mannings or depth-varying mannings, the log-law roughness must be set to zero (default).
To utilise log-law roughness, the roughness height must be greater than zero.
A roughness height of less than zero is not permitted.
Suggestions
Ensure that all materials that utilise log-law roughness have positive roughness heights.
