Indira Gandhi International Airport is the primary international airport of the National Capital Region of Delhi, India. It is the busiest airport in India, with the commencement of operations at the new Terminal 3.Spread over an area of 5,220 acres (2,112 ha) of land, Delhi airport serves as the primary civilian aviation hub for the National Capital Region of India.
A recent heavy rain led to water logging at IGI airport due to the poor drainage systems causing inconvenience to passengers who waded through knee deep water while the baggage handling system was left crippled. Geokno carried out the storm water modeling project to identify the problematic area and to propose a better mitigation plan.
The existing drainage system on the IGI Airport area consists of a series of open and closed drains. IGI Airport drainage system catchment area divided into two major categories namely Northern Catchment and Southern Catchment.
Our storm water experts identified the locations in the existing drainage system with high risk of flooding situation with today’s situation in a created flood model and the Land use/Land cover of existing drainage system catchment area along with catchment area statement was prepared.
The hydraulic analysis was done to calculate the accumulated inflow and outflow during the rain fall. The obtained results were accurate and replicating the on ground flood situation.
