Tuflow and estry manual Version 3

Bed Resistance Values	Bed resistance values are to be reviewed by an experienced modeller. The review should focus on checking at least one of: the material values in the .2dm file; the grid “Mat” or “Manning_n” values in the _grd GIS check file using Write Check Files; or specifying weir output (see Map Output Data Types) if using the weir approach. The reviewer should be looking for: relative consistency between different land-use (material) types; and values are within accepted calibration values.
Calibration / Validation	Check that the model calibration or validation is satisfactory in regard to the study objectives. Identify any limitations or areas of potential uncertainty that should be noted when interpreting the study outcomes.
