Surface tension, trapped waves, and hydraulic falls

flow-over-obstacleThe paper “The influence of surface tension upon trapped waves and hydraulic falls“, co-authored by C. Page, S Grandison and E. Parau, has been published in the European J Mechanics B/Fluids. The paper models the free surface of an ideal fluid flowing past submerged obstacles. For hydraulic falls they show that the solution is not unique, and they find gravity capillary waves trapped between two obstructions. A link to the paper is here.
