The other parameter that will be used to calibrate the model is the roughness at the main tributaries. First of all, this object should be available in the scripting environment. Look for the object RoughnessType in the online help, and add the corresponding import to the first region of the script. The roughness at the main tributaries is the first object (so the index is [0]) in the list of roughness items, as shown in the picture above. The object to grab is the corresponding network coverage. We will assume that this parameter can that the roughness type Strickler coefficient ks can change from 24 to 34 m1/3 s-1 in steps of 2, so a total of 6 different cases.
