‫‪The Suez Canal Corridor Area Project‬‬
Project aim
• The project aims to increase the role of the Suez
Canal region in international trading and to
sustainably develop the Suez Canal Corridor area
in a safe environment.
Aim of work
The present work is an integral study
environmental analysis and management to:
of
1- Asses prevailing geoenvironmental hazards with
an emphasis on problems associated with soil
desertification, land erosion, water logging, tectonic
activity, pollution and flash flood hazards.
2- Propose adequate and economic safe designs
to mitigate the prevailing geoenvironmental
hazards.

CONCLUSION
Data integration and analysis indicate that the area is under
threats by five types of geoenvironmental hazards which are;
 Water logging and soil salinization along the middle and
northern newly irrigated areas;
 flash floods hazards along the northwestern Gulf of Suez
industrial area;
 moderate to low seismic activity along the canal main course;
 pollution threats for both saline and fresh water resources;
land subsidence
and
Mediterranean coastal area.

47
CONCLUSION
The area witnessed a rapid agricultural development in the past three
decades, and the environmental changes were very remarkable
therefore, the present study gives some applicable mitigation
measures for the predicted hazards.
The seismic activity hazard should be taken into consideration during
the selection of tunnel sites, especially those proposed for the
southern parts of the project area.
In conclusion, the project area could be ranked from the geotechnical
point of few as medium to low risk ranked area, therefore, the
proposed mitigation measures could easily mange most of these
prevailing hazards.
