The Journal of Hydraulic Engineering accepts original contributions that describe the analysis and solutions of problems in hydraulic engineering. Technical Notes may present a problem, without solution, of common interest. Topics range from flows in closed conduits to free-surface flows (canals, rivers, lakes, and estuaries) to environmental fluid dynamics. Topics include transport processes involving fluids (multiphase flows) such as sediment and contaminant transport, and heat and gas transfers. Emphasis is placed on the presentation of concepts, methods, techniques, and results that advance knowledge and/or are suitable for general application in the hydraulic engineering profession.
