Abstract:

 The coastal cities in many locations around the world suffer from liquefaction hazards because of saturated clastic deposits. These hazards are affecting the environment, humans, and construction. The New Rosetta City is one of the coastal cities located in the northwest of the Nile Delta. The analyzed data were derived from 480 standard penetration tests and 290 shallow seismic profiles. New Rosetta soil profile comprises fine to medium, and loose to medium dense sand with silt overlay, two layers of elastic silt, and lean clay. The collected data from the field and laboratory were input into the NovoLIQ program as a cyclic resistance ratio. These data correspond to a five-earthquake magnitude range between 5.5 and 7.5, representing a cyclic stress ratio. Two types of data were input to analyze liquefaction probability and create a geo-hazards map. There are two groups of liquefaction hazards in New Rosetta, which include an earthquake scenario with a magnitude less than 6.1, which is safe and gives a factor of safety>2.1, and this group has low liquefaction susceptibility< 5.5%. The second group records for earthquake scenarios with Magnitude> 6.1, which gives a factor of safety <1.3 and has a large liquefaction susceptibility of>25%.
