Storm water management of Mumbai city by using pervious concrete on GIS based platform

Abstract

Flooding is major cause in urban area particularly in Mumbai City which is due to haphazard alterations in land use–land cover (LULC), escalation in the amount of precipitation by virtue of climate change and related impacts due other hydrological changes augmented with deterioration of life and properties. Due to urbanization most of the city has gotten embedded in concrete and by the virtue of which the rainfall gets converted to runoff. The present SWD system in the city is more than 150 years old and 186 outfall also not in use in high tide associated with heavy rainfall situation. In relevance to the implications as stated above, Greater Mumbai is facing reckless Water Logging Problems in many low lying areas from the past 20 years. So, to eradicate and abolish this problem permeable concrete is a perfect solution which should be eco friendly, economical and universally accepted. In this study characteristic of permeable concrete with its type, mix design and application is suggested data base is created to get comparative idea for the same. By clicking on the respective flood spots one can avail the information pertinent to that flood spot location in terms of pervious type suitable to that location. Geographic Information System (GIS) proves to be a can prove to be a very effective tool for integrating & managing various types of information related to this Storm water Management.
