Facts & Figures on floods in Kuwait
Destructive Floods occur during heavy rainstorms
with rainfall amounting 30-40mm in one storm
lasting 4-6 hours.
Parts of Kuwait were subjected to flash floods during
2nd February 1993 (40mm within 6-8 hours), 11th
November 1997 (105 mm within 4-6 hours), January
2004, January 2007, April 2008, December 2009 and
November 2012.
The flash floods cause intensive damage to the
physical infrastructures such as roads, fences, water
wells, oil facilities and others.
Two Remarkable Flood Events
November 1997 : 105 mm within 4-6 hours (largest
amount of rainfall in one day during 41 years (Al
Sabah and Borbia, 1998)
2 February 1993 : 40 mm within 6-8 hours :

Managing Flash Floods in Sabah Al Ahmad
Nature Reserve (SANR)
Why ??? How ???

Watersheds of SANR
 Main : Jal Az zour Hilly Terrains (100-120 m above
sea level)
 Secondary : Terraces , cliffs and isolated hills (40-60
m above sea level )
 Urban watershed (Human made): Roads and road
embankments (10 – 20 m above sea level)
Urban Watershed
Hydrographic Basins of SANR
 Exterior : Wadis (dry water courses)
 Interior : closed basins (Playas)
 Urban wadis : associated with human pressure and off
road traffic.
Effective Wadis : headwaters start at Jal Az Zour main
escarpment and the wadis drain in the coastal plain
Managing flash floods WHY ???
 To control soil erosion by runoff.
 To protect plant species such as Haloxylon
salicornicum and wildlife habitats.
 To minimize local sources of dust.
 To protect infrastructures such as fences and roads.
Soil Erosion by runoff water
(Western Part of Jal Azour water shed
, March 1997)
 At least 8 cubic meters of good soil
was lost in one storm.
 No soil recovery under the
prevailing conditions.
 Sole practical solution : water and
soil conservation.

Managing flash floods HOW ???
Applying passive water harvesting with
minor active harvesting techniques.
Passive water harvesting : Cost effective &
environmentally sound.
Approaches of water harvesting
 Passive
Systems that slow flood water, allowing it to seep into the soils.
 Active
Storing water in aboveground or belowground tanks.
Dams & cisterns.
Ribbing & Pitting

Conclusions & Recommendations
 Dust and sand storms, droughts and flash floods are
the most significant natural hazards in Kuwait.
 Contingency plans for managing natural hazards are
not yet completed.
 Managing flash floods is essential. It starts with
delineation of drainage basins using Arc GIS/high
resolution satellite images and ends with contingency
plan .In between there is an early warning system.
 Passive measures of water harvesting is proposed .it is
cost effective and environmentally friendly.
