Moulinet is an online software for processing gaugings by exploring the velocity field, available at https://moulinet.g-eau.fr.

Developed by the UMR G-EAU under the OFB-Inrae grant agreement, it enables the estimation of flow rates from gauging data collected using electromagnetic current meters, reels, or gauging rods (Le Coz et al. 2024).

Moulinet implements methods with a reduced number of points on a vertical (1 to 6 points) and the arithmetic flow calculation method known as the mid-section methods, derived from the ISO 748 (2021) standard. It also implements the Q+ method for uncertainty calculation described in Le Coz et al. (2012) et Le Coz et al. (2015).
