-River diagnostic variables can be calculated for the main river. A river water depth (//d//) and river velocity (//u//) can be calculated from hydraulic geometry for the main river and the calculated main river flow (//q//).

A river water depth (//d//) and river velocity (//u//) can be calculated from hydraulic geometry for the main river and the calculated main river flow (//q//). In the case of updating of flow in a subbasin with no outlet lake, the updated (main river) flow is used. The equation coefficients are general ​parameters ​(//​c,​f,​k,​m//​).

 With a given rating curve for main river flow, the water level of the river (//wr//) can be calculated by the inverse of the rating curve. Basin dependent values for reference level (//w0//) and the rating curve coefficients are input. Two rating curves may be given for each  main river, one for general and ice free condition and one for use with ice on the river. The rating curve for ice conditions are only used if one is given for no ice conditions. With a given rating curve for main river flow, the water level of the river (//wr//) can be calculated by the inverse of the rating curve.
