Anthropogenic disturbance at the Nile Littoral Cell, southeast Mediterranean

Abstract

The natural cycle of sediment transport and deposition along the Nile Littoral Cell was profoundly altered during the 20th century and the present conditions along the continental shelf are a product of natural processes and anthropogenic interference. A major control on the sediment budget of the Nile Littoral Cell was the Aswan Dam construction as it terminated the transport of fine suspended sediments into the Mediterranean. Furthermore, the growing agricultural land use, industrial activities and demographic growth along the coast affected sediment transport and pollution. In recent years we analyzed and monitored sediment characteristics and flux, and pollution at the Haifa Bay and its surroundings, and present sedimentological and geochemical evidence for the change. 

Dr. Revital Bookman is a lecturer at the Charney School of Marine Science at the department of Marine Geosciences and currently focuses on modern and Late Quaternary marine sedimentary records. Her research specializes in sediment transport and deposition related to climate-driven and earthquake-induced processes. In addition she studies anthropogenic disturbance and pollution in aquatic environments. Her environmental research focuses on heavy metal pollution in aquatic archives. Revital earned her Ph.D. in the Institute of Earth Sciences at the Hebrew University (2004), studying historical climate change and paleo-earthquakes from the Dead Sea lacustrine records. In her postdoc at Syracuse University (NY) she developed lacustrine records for heavy metal contamination and identified regional atmospheric sources using 210Pb radiometric dating, applicable in studies of human impacts.
