7But Canopus, along with other cities on the stretch of coast where five branches of the Nile once met the Mediterranean sea, has long since been lost -- drowned by seismic activity coupled with a neglect of sea defences.
8The silt could be made into mud bricks for building
9How have people affected the DELTA (landform)? 1970 Aswan Dam builtRiver no longer floods andsilt no longer deposited
10The river used to deposit 120 million tonnes of silt onto the delta each year. Now it is only 50 million tonnes because the rest is trapped at the Aswan Dam.
11So now the delta is being eroded by the sea at up to 30 metres a year.
12And with Global Warming causing sea level to rise the delta is even more at risk.
13In the next 50 years, Egypt’s coastal zone, home to more than 40 percent of the population, stands to be severely damaged byflooding,groundwater salinity anderosionresulting from rising sea levels associated with Global Warming.
14Such a rise could potentially create as many as 14 million internally displaced persons With about 40 percent of all Egyptian industry located within the delta area
15How is it being managed?In the fishing village of El-Burg there is an enormous cement levee which was built six years ago to save the village from being sucked into the sea.The delta is sinking at 5mms per year.
