[en] Within the framework of development of PKW use for rehabilitation as well as for new dam projects, the development of efficient design methods is essential. Currently, the design of PKW projects is done by mean of scale modeling, on the basis of a geometry initially designed based on the general knowledge issued from idealized experimental studies and former PKW buildings. This paper presents a systematic method for PKW preliminary design. The method is based on extrapolation of existing experimental results to develop one or several available project designs, regarding the project constraints (discharge, reservoir levels, available space, …). The model permits then the optimization of the design depending on technical and economical interests (increase of the safety, decrease of the maximal head, limiting the weir dimensions, limiting construction costs, …). The application of the method to a new large dam project is presented, highlighting the interest of the method for the optimization of the design depending on technical and economical interests.
