WAVE CLIMATE OF LARGE RESERVOIRS AND A REVISED WAVE HINDCAST FORMULA

Abstract

Since impounding of the various reservoirs of the La Grande Complex in northern Quebec, the riprap of several dams and dykes has suffered some damage during the fifteen-year period that followed. A mandate was given to the Societe d'energie de la Baie James (SEBJ) in January 1992 to review the riprap design and evaluate the necessary repairs. This paper focuses on the revaluation of the design wave with revised wave hindcast formulas based on the large amount of wind and wave data collected.
