Geomorphological effects of the Dead Sea-level lowering upon the Mujib delta between 1953-1993

Abstract EN

The study deals with the geomorphological characteristics that Al-Mujib T>elta has developed due 10 the lowering of the Dead Sea levels during ttie period U&3?19&t-1fe* air photo analyses and the fieldwork investigations have ted to embody such characteristics and changes laAhw the framework of tee stages of development.

I» si^ stages, detwdaasmol the delta has been conducted by Al-Mujib River through vertical and lateral eroslbn processes, leading to major geomorphological deltaic changes.

Such changes cover the concentration of coatse and large stream bed sediments, the delta morpholo^ and an expansion in its area.

Other effects include the exposure of both stream and marine terraces and a decrease in the area of the delta plain, Finally, the study concluded a hypothesis that proposed a semi-cycle of erosion that deltas, in general, may experience when their base-levels become subject to any lowering.
