Please enter input data [on left] and press 'Calculate' below.

⇐⇐⇐

♦ Input data types 1 and 2 [channel hydraulic and sides material characteristics] are always required.

♦ Input data type 3 is required only if the material of the bottom is different from the material of the sides (See Description). If input data type 3a is left blank, the program will assume that the material of the bottom is the same as that of the sides [input data type 2].

♦ Input data type 4 is optional [Default is None].
