Flow is a crucial variable in water resources, although its determination is challenging. Rating curves are standard but have conceptual limitations, leading to significantly high uncertainties. Hydrodynamic models offer a more precise alternative, but t...

Accurate discharge measurement is mandatory for any hydrological study. While the ?velocity? measurement method is adapted to laminar flows, the ?dilution? method is more appropriate for turbulent streams. As most low-gradient streams worldwide are neith...
