Urban Floods Disarraying Lives
2015 Chennai: 500+ people killed, 1.8 million lives displaced. 2014 Srinager: The city submerged in waters for days, leaving thousand stranded. 2005 Mumbai: Heavy rains & floods paralyzed mumbaikars.
Challenges in Flood Monitoring
Data Collection
Data Collection is fragmented and not freely available.
Manual and time consuming process to collect and consolidate flood data.
Lack of real time system to analyze and monitor flooding events.
Forecasting
Existing models for flood forecasting are conventional and simple.
Weather forecasting remains uncertain due to lack of precise data.
Absence of computational and analytic tools to predict an event of flood..
Warnings
Lack of any relevat flood warning and notification system.
The available flood warning systems are conventional and slow resulting delay in arrival of informations.
Aurassure (Real Time Flood Management System)
Deploy
Can be easily clamped to any pole, walls, in critical regions of the city like dams, canals, streets etc.
Visualize
Visualize real-time data on water levels, GPS location etc. captured by the sensors.
Warn
The data is analyzed continuously and people are warned of the risks for flooding
The Aurassure solution for flood monitoring is an automated flood warning and prediction system for cities and communities, providing real-time warnings to reduce flood-related disasters by utilizing IoT and BIG Data technologies.
Architecture
Figure: Aurassure Flood Monitoring Architectural Diagram
Sensors for sensing and monitoring water, inundation levels, rainfall, precipitations and other environmental parameters are deployed at
critical zones of the city like traffic posts, dams, pumphouse, canals etc.
These sensors continuously transmit data acquired from the surrounding for storage to local or a central server through available mode of
communication such as GSM, GPRS, Wi-Fi etc. The application server analyses and processes the data received into meaningful information’s in real-time and makes them accessible to different departments, organizations, communities and peoples to notify them in case of any alerts and assist in disaster mitigation anddisaster preparedness of the city.
Pumping Station Operation
(Sensor Components)
The sensor nodes installed at sewerages, drainages and
pump stations will monitor the operational status of the
pump (on/off) and also the water levels at penstock &
sump. The sensors are equipped with local triggers and
alarms to warn the pump operators whenever the water
levels go beyond the acceptable levels.
Sump/Penstock
Every city drainage system has sumps & penstocks to store the excess runoff of surface water during heavy rainfalls. The water is filtered & conveyed to canals, rivers whenever it reaches acceptable limits.
Pump Operation Status
The sensors are installed to monitor the operational status of the pump weather on/off.
Canal Level Sensors
The nodes can be installed to monitor water levels of rivers and canals during and after extreme rainfall events. The sensors will monitor the water level for both open and gated canals.
At gated canals the nodes can be installed on both sides of gates to monitor flood water, whenever the water overflows the danger mark the excess waters will be released to the rivers, the sensors will also monitor the gates opening and closing status.
Street Inundation Sensors
Inundation sensor nodes can be deployed at the most vulnerable spots of the city such as traffic junctions, schools, hospitals, govt. offices, shops, & residential areas to measure the inundation of streets/roads.
These sensors will be accompanied by environment sensors for year-round environmental monitoring providing information on temperature, humidity and air quality across the city.

Solution Benefits
Citizens
Citizens can make use of valuable data to take preventive measures to reduce the impact of poor air quality and can protect their homes, business from flood damage.
Civil Socities & Academia
Civil Society can use data to develop awareness programs to make the city ready for extreme weather events. Academia can conduct research works to develop risk informed urban planning.
Communities
Communities can plan responses based on early warning and real-time inundation status and can disseminate flood warning and evacuation information to vulnerable peoples.
Private Sectors
Private Sectors can develop context specific innovative products to deal with flood related hazards, air pollution etc. improving people-specific needs before and during extreme events.
City Officials
City officials will get valuable data sets to develop flood risk informed urban plans in synergy with other initiatives for a more resilient city. Flood prediction will help authorities evacuate people and property away from downstream in time.
Shops & Vendors
Shops and vendors can monitor flooding near their establishments and can reduce flood vulnerability of assets by installing shop-front sensors.
Stakeholders
Stakeholders can become more empowered and engaged by taking ownership of the system and ensuring regular data collection and sustainability of the system.
Vehicle Tracking
Vehicle tracking through GPS will inform motorists the easy routes to dodge flood and traffic on streets also the informations can be disseminated through large screen displays, websites etc.
