  • Analyzing the shortcomings of Flood Early warning system in Pakistan Proposed By: Dawood Jan Ismail Khan Kiramat Ullah Supervised By: Dr. Khurram Shehzad Department of Civil Engineering Gandhara Institute of Science and Technology Peshawar Peshawar03/17/13 1
  • IntroductionLiterature ReviewProblem StatementObjectiveMethodologyWork PlanReferences03/17/13 2
  •  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.03/17/13 3
  •  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 Authorities03/17/13 4
  •  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 coefficient03/17/13 5
  •  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.03/17/13 6
  •  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.03/17/13 7
  •  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.03/17/13 8
