SIMULATION OF URBAN DRAINAGE SYSTEM IN SAID UL AJAIB, NEW DELHI USING GIS SOFTWARE

Abstract

Rapid urbanization has opened the way to congested cities such as New Delhi, Mumbai etc. and has been very challenging for urban drainage systems. Poorly designed urban drainage systems, congestion of the stream channel, overcrowding, expansion of urban infrastructure without appropriate consideration of drainage issues, increase in paved surfaces, and climatic conditions are the major causes of these disasters. As a response of these circumstances, flash floods occur, resulting in both ground and surface water quality deterioration. In order to have better results, competent planning, analysis, and design of urban drainage skills are expected. In this study, ArcGIS software is used to simulate the urban drainage system. The rainfall data required is gathered from Irrigation and Flood Control Department, Delhi. For a drainage region in SAID UL AJAIB, near Saket metro station, Delhi, India, the simulation was done to understand problems associated with inadequate urban drainage. From the results obtained, it was seen that some parts of Sail ul Ajaib area are frequently affected by flooding.
