Between 18:00UTC on Friday 9th November and 12:00UTC on Saturday 10th
November 2001 260mm of rainfall was recorded at Bouzareah,
compared to the November average of just 96mm. This extreme rainfall
resulted in landslides and flooding, causing immense damage to the
Bab-el-Oued district of Algiers and affected the lives of more than
2000 people. In this paper, key results from a modelling study of
this event using the UK Met Office Unified Model at global (60km),
regional (20km) and national (4km) horizontal resolutions are
described. In general, it is found that the event could be well
forecast with increases in resolution leading to better predictions of
both the distribution and intensity of the rainfall. The role of the
local orography and latent heating are also discussed.
