<br />2.23 <br /> <br />3. Assign roughness, area, and width reduction factDl"S for each grid element. <br /> <br />.. <br />4. The 1 ami nar flow res i stance value has been set to a preset value to refl ect <br />the grid element roughness. The value 2,285, when multipl ied by the <br />Mannin\J's n values will result in an appropriate laminar flow roughness <br />coefficient K. Raising or lowering the value 2,285 will effect the <br />magni tude of 1 ami nar shear stress component in the momentum equat i on. <br />Furthel" description of the K value is provided in Appendix B. <br /> <br />The Rudd Creek field verification of the MUDFLOW model was used to <br />cal ibrate the 2,285 laminar roughness value. The variable AMANN in the data <br />input file can be used to increment all the roughness Manning's n value on the <br />grid sYstem. <br /> <br />Q <br />
