Flood Inundation Warning and Relief System Based on GIS and Remote Sensing

Abstract

Abstract: Due to climate change and uncontrolled
urbanization, frequencies of floods are increasing these years.
In a developing country like India, flood creates a great havoc
which takes many years to get restored. To mitigate the affect
of flood disaster, an accurate flood inundation warning is
required.
In this system, a geographic information system (GIS) model
is developed on the basis of Digital Elevation Model (DEM) and
the shapefile of buildings. They accurately analyze the land
behavior in presence of flood and identify the flood inundation
risk of different places. This would be helpful to take active
measures to mitigate the destruction caused by flood, in time
being. Global Precipitation Measurement’s (GPM) half-hourly
rain data is used to find the impact of rain on current flood
conditions in various areas; this helps to warn the people living
in nearby places, as they also may have threat of life and
property.
This system also contains the flood relief system which is a
web-based system (developed using PHP) having web
application and MySQL database, to create a platform that
provides a foundation that prepares the donors to help the
victims of flood with various kinds of donations. This system
informs the donors by sending an SMS using a GSM module.
This is done to prepare the donors with their donations,
immediately after the flood warning is released. These
donations would equip the authorities to provide essential
needs of the flood victims. This system is developed for
Mumbai city, India’s largest city as it is a city affected by flood
almost every year causing great destruction of property and
life.
