Fish ladders: Number of falls
This tool is an aid for the pre-dimensioning of a fish ladder: it allows to calculate the missing value of the three quantities:
- the total fall (\(\Delta H_T\)) in m;
- the fall between basins (\(\Delta H\)) in m;
- the number of falls (\(N\));
as well as the residual fall (\(\Delta H_R\)) in m.
\[\Delta H_T = \left ( \Delta H * N \right ) + \Delta H_R \]
