Abstract

The study of recent trends in the geomorphology of rivers is one of the significant topics identifying the quality and patterns of modern topics and applications, as well as the criteria for degrees of dangers associated with them in international periodicals. The relative importance of recent trends in the subtopics of river geomorphology has varied. However, there is a tendency towards interest in geomorphological phenomena in the water stream, sediments, whether mechanical or chemical, and then the study of factors and processes. Accordingly, the prevailing trend is research related to geomorphological processes and phenomena rather than factors, applied aspects, and modern technologies, noting the increasing interest in modern technologies in river geomorphological studies recently. This is due to technological developments occurring worldwide and at the level of various sciences. The criteria for degrees of erosion danger are based on the general average of the agricultural property, choosing the square shape as an expression of the general shape and calculating the eroded area with it, and then finding the annual rate of the eroded part of the agricultural land. The degrees of danger resulting from the deposition process were determined based on only two inseparable criteria: the depth of the submersible and the width of the navigational channel.
