Le résultat technique de la présente invention consiste en la formation d'une crête d'onde stationnaire qui possède une vitesse de déplacement longitudinal du flux moindre que dans les dispositifs connus atteignant un minimum dans la zone du sommet de la vague, ce qui améliore considérablement les propriétés d'utilisation et permet à une vague ainsi formée de se rapprocher d'une vague formée dans des conditions naturelles en mer dans une zone d'augmentation régulière du fond marin ou océanique dans la zone côtière; il est ainsi possible d'ajuster les paramètres de la vague afin d'atteindre des indices optimaux pour chaque cas concret (comme déterminer les paramètres de la vague pour des sportifs de différentes catégories, des amateurs, des enfants, des adolescents, etc.). Ce dispositif de génération de vague artificielle comprend des premier et second canaux de section transversale continue, et une turbopompe hydraulique connectant les premier et second canaux via des adaptateurs reliant l'entrée du premier canal et la sortie du second canal à la sortie et à l'entrée de la turbopompe, respectivement; le premier canal comprend une partie de sortie courbe, et la sortie du premier canal est reliée à l'entrée d'une buse se rétrécissant disposée selon une certaine inclinaison sur le côté depuis la sortie du premier canal; l'espace interne de la buse est délimité par un plan supérieur ajustable et un plan inférieur relié par un angle courbe au premier bord du premier plan de fond disposé selon une certaine inclinaison du côté de la buse dont le second bord est relié en douceur au premier bord de la surface de fond concave d'un déflecteur, dont le second bord est relié par charnière au premier bord du déflecteur et se transforme en un plan de fond à un angle droit; le plan inférieur du déflecteur se transforme en une niche sous le déflecteur dans laquelle se trouve un cylindre hydraulique permettant de commander le changement de l'angle d'inclinaison du plan du déflecteur; le second côté de la niche sous le déflecteur est relié au premier côté du second plan de fond dont le second bord est interrompu par un collecteur d'eau dont la sortie est reliée à l'entrée du second canal; l'espace du collecteur d'eau est délimité par une paroi plane inférieure dont le bord inférieur est relié en douceur au bord inférieur du second canal; le dispositif comprend un espace ouvert délimité d'un côté par la plan supérieur de la base et, de l'autre côté, par le second bord de la paroi horizontale du collecteur d'eau; le premier canal, le second canal, a buse, le collecteur d'eau et l'espace ouvert sont délimités sur les côtés par deux parois verticales qui sont de préférence parallèles, et le dispositif comprend également un fond de protection perforé disposé selon une certaine inclinaison par rapport au collecteur d'eau vers le déflecteur et fixé au second plan de fond, à la paroi verticale du collecteur d'eau et aux parois verticales.
