caractéristiques géométriques du dispositif au débit d’alimentation et à la puissance dissipée fixés, compte tenu des critères de conception adaptés aux espèces cibles.\n\nDans le cas d’une échancrure à profil ½ triangulaire, il convient de diviser par 2 le coefficient de débit d’un déversoir triangulaire renseigné par défaut (1.36) pour obtenir le débit de
