Coastal engineering and Harmful Algal Blooms along Alexandria coast, Egypt
The coast of Alexandria has been subjected to successive engineering alterations since 1998. Such alterations have affected the topography of the coast as well as the water quality, the phytoplankton productivity and diversity. In 1998 protective wave breakers were built in order to reduce erosion a...
