Abstract—Egypt is considered an arid country and depends
mainly on the Nile River and groundwater reservoirs to supply
water for drinking and various uses. The northwestern coastal
zone is one of the regions that rely heavily on groundwater and
rainwater for drinking and irrigation. As a result of changes in
climate and the rise in sea level, the increase in seawater
intrusion is growing. Furthermore, groundwater exploitation
and increased pumping of some wells installed in this area have
a negative impact on the amount of water in the region’s
subterranean reservoirs. One of the approaches suggested for
managing freshwater lenses floating on top of seawater from
saltwater intrusion in this region is to recharge the aquifer
lenses with fresh water. This can be done either by injection
wells or by use of groundwater mounds, i.e., infiltration
trenches. Due to the expected higher cost operation of injection
wells, it is interesting to study the recharge of freshwater lenses
through the use of groundwater mounds. Studies have been
carried out in the past on the Sidi Kirayr area in terms of
recording the water table levels and the amount of rainfall
before and after the rainy season. However, we propose using
an environmentally sustainable economic solution to recharge
the underground reservoirs through the use of rainwater
instead of letting it run off into the sea. In this respect, an
infiltration trench is designed to recharge the aquifer in the Sidi
Kirayr area. Two design types for the trench are proposed, with
the geometrical calculations of the appropriate dimensions. The
trenches are suggested north and south of the asphalt road in
the area of Sidi Kirayr, providing that the trenches can be
recharged by rainfall or surplus water when being available
from other sources.
