Abstract-Two severe tropical cyclones hit the Sultanate of
Oman; Gonu in June 2007 and Phet in June 2010. Wadi
Uday passes through the main urban areas of Muscat, the
capital city, which was among the most affected areas. This
paper aims to evaluate the impact of flood hazards on land
use, in Wadi Uday lower basin, using Remote Sensing (RS)
and Geographical Information Systems (GIS) techniques.
The Wadi basin was captured using 40 meter Digital
Elevation Model (DEM), while total damage were examined
using Ikonos images which acquired in 12/6/2007, coupled
with land use dataset for 2003, and rainfall record of the
past 20 years. The analysis showed that the highly affected
land use categories were the recreation and residential
areas with a ratio of 31% each. Roads, agriculture and
public buildings were moderately affected. Further research
will compare these results to that of Phet (June 2010) on the
