Diefenbaker Lake : effects of bank erosion on storage capacity / R.O. Van Everdingen. : En36-515/10E-PDF

"The creation of a surface-water reservoir exposes valley slopes, that were originally formed by glacial or runoff erosion, to the erosive energy of two or three new agents: waves, ice and, under the right circumstances, groundwater movement. This will result in accelerated erosion of the reservoir banks during the early years of the reservoir's useful life. Continued modification of shore profiles will adapt the exposed slopes to the new conditions and the erosion rate will consequently decrease with time. The effect of bank erosion in terms of reservoir economics will usually be threefold:(1) increase in the surface area of the reservoir, resulting in increased evaporation, (2) formation and increase in the width of an accumulation shelf (beach) and (3) decrease in storage capacity by deposition of erosion products"--Introd.
