Hydrologic Modelling Of New Islamabad International Airport

HYDROLOGIC MODELLING OF ISLAMABAD INTERNATIONAL AIRPORT DEVELOPMENT FOR SUSTAINABLE WATER SUPPLY

 ASSESSMENT / REQUIREMENT

The basic and pre-requisite requirements included:
• The minimum water supply requirement for the terminal building inclusive of fire fighting etc is 2.0 MGD to 7.5 MGD which should sustain for 3 to 4 months.
• About 12000 Aft storage capacity is required by constructing a single or multiple water storage interventions / mini dams.
• Funnel areas of the runways should be avoided being hazardous.
