I worked at Azhar University, Faculty of Engineering, and civil engineering Department as Associate Professor of hydrology and water resources since 1999. Befor such date, I worked at water resources research institute in Cairo in the fields of hydrology and water resources planning for 13 years. During such period, I had a good experience during the work with foreign consultants in many research works concerning Sinai water resources funded by foreign governments. I made a lot of consultation in and outside Egypt in the field of flood protection, hydrology and assessment of water resources. I supervised many M.Sc. theses in the field of integrated water resources and hydrology.
