Land reclamation using construction waste for offshore Gaza fishery port

Abstract EN

The world experience rapidly growing in population density and lack of areas especially coastal areas, which is considered the most vital, economic and cultural areas around the world.

This force the experts investigating different suggestions such as sea reclamation and its exploitation for many goals.

Gaza Strip is considered one of the most densely area in the world.

Where the population is nearly two million inhabitants by 2016 while the area is 365 square kilometers.

This reflects on the availability of lands in the future that will raise the lands prices.

Moreover, the existing fishery harbor constructed in 1994–1998 period has locally disturbed the coastal erosion and sedimentation pattern and resulting in sand erosion problems.

On the other hand, two million ton of debris have been accumulated in the last aggression on Gaza Strip in 2014.

This massive volume of concrete rubble is considered huge burden on the landfills in the Gaza Strip, which are already overloaded.

In this study, an investigation of the best way to dispose these debris by land reclamation in Gaza Strip.

In this study, it is proposed to relocate the construction features of the Gaza fishery port for better sediment transport and hydraulic conditions.

Therefore, the study methodology started with estimation of the construction waste quantity resulted from 2014 aggression, then ensuring its testing results, specifications and possibility of using it in land reclamation.

Furthermore, the existing Gaza fishery port sediment transportation and features were studied and its bathymetry was identified.

As a result, the new proposed reclaimed area was identified in west of the existing western breakwater at Gaza fishery port and its area was estimated according to estimation the quantity of debris resulted from removing the existing breakwaters in addition to construction wastes resulted from 2014 aggression.

The total estimated quantity of available debris is about one million cubic meters, which adequate to reclaim about 11 hectares.

However, the new reclaimed area should be surrounded by sheet piles, so the sheet pile type is assumed to be PZC 28 and finally the total cost of the proposed reclaimed area was estimated as USD130 per square meter of reclaimed area.

Finally, to facilitate transportation and movement through this reclaimed area, the bridge is recommended to be constructed.

Finally, the cost of sea reclamation is feasible especially that Gaza fishery seaport is very vital and important place, which will be as a fishery port and for recreational activities.
