Abstract

The retreat of the Lisan Lake, the predecessor of the Dead Sea, left behind a sequence of shore terraces. Three cross-profiles of these terraces were taken with the aid of a level. The terraces were found to be horizontal, undisturbed and merging from profile to profile. Accordingly, the three cross-sections were integrated into one generalized profile consisting of 28 terraces. The good degree of preservation of the terraces is related mainly to a gravel capping. For the purpose of analysis, the terraces were divided into two sections, a riser triangle and that of the tread. According to the gradient of the treads and the distribution of the superficial gravel and boulders, the treads formed the foreshore whilst the terraces were active shorelines. By analysing the geometrical relationships between the terrace units, a method was found for distinguishing between actual and pseudo lake terraces. The height of the tread is suggested as a means for evaluating the wave height at the different stages of the Lisan Lake.
