3.  Overflow or inundation that comes from water body may cause or
threatens damage. It may be caused due to:
▪ High rainfall
▪ Snow melting
▪ Breaching of embankments of a canal
▪ Failure of Dam/reservoir
▪ Deforestation (anthropogenic cause)
 Floods without proper warning and forecast may cause the loss of:
▪ Human Lives
▪ Infrastructure
▪ Livestock
▪ crops
 Pakistan has been struck by 150 major disasters in the last 65 years in
which most are floods.
 Floods in July 2010, affected about 20 million Pakistanis and inundated an
area of 100,000 sq-km of the country, and 2000 casualties has been
recorded.
 Overall loss of US $ 10.05 Billions.

4.  To prevent this situation, efforts be made urgently to acquire the best
early warning system in order to save lives and protect livelihoods.
 Radio, Television, Newspaper and social media should be utilized for
conveying early warnings to population at risk.
 The agencies responsible for warnings propagation and flood forecasting
in Pakistan.
 Pakistan Metrological Department
 Federal Flood Commission
 National Disaster Management Authority
 WAPDA
 Irrigation Department
 Local Authorities

5.  UNESCO worked for the early warning systems over the world.
 Program started in Pakistan, funded with a $3.5-million grant from Tokyo, will
install a flood-forecasting system using satellite-based rainfall data at government
agencies, including the Pakistan Meteorological Department. It will also carry out
risk mapping of flood plains along the Indus River. 1
 Use of Weather radars in flood forecasting, remote area can be monitored through
these radars which are not physically accessible.
 Hydrological information development system may created by using GIS and
hydrological watershed parameters such as.3
 Design storm
 Soil hydrology
 Time of concentration
 Runoff coefficient

6.  Early warning system for flood in Pakistan is not covering the upper
Indus above Tarbela and Kabul river above Nowshehra.4
 Pakistan warning system for flood has poor mapping.
 Poor early warning system for floods may increase the damages of
the livelihoods and also infrastructures.
 Poor flood forecasting is the cause of disastrous affects on the
people at risk.
 Poor warnings may increase the post flood cost in case of urban
floods.

7.  To investigate the shortcomings of flood forecasting
 To investigate the shortcomings of communication of flood
warning
 To investigate the shortcomings of mechanism of flood
preparedness
 Recommends the set of actions and corresponding resource
requirements that need to be undertaken in order to
enhance the effectiveness of Flood early warning system in
Pakistan.

8.  Finding the Current conditions of early warning system of floods in Pakistan
that are:
 Density of gauge stations
 Forecasting model in place
 Efficiency of flood forecasting model
▪ Accuracy
▪ Authenticity of forecasting
▪ Conveying Timing of warnings
▪ Reliability
 Recognition of weak zones (if any) in early warning system for floods in
Pakistan.
 Role of responsible agencies in early warning system
 Comparison with international standards of early warning system for
hydrological disasters
 Suggest the initiatives for improvement of early warning system for flood.
 Writing the final report.
