# IoT Solutions Detect Floods and Proactively Minimize Risk
Marc Pégulu
Densely populated urban cities are now home to an incredible [83%](http://css.umich.edu/factsheets/us-cities-factsheet) of all people living in the United States. As more people flock to the opportunities and culture available in urban areas, the risk of flooding is rising dramatically. In fact, flooding resulted in [$45.9 billion](https://blogs.scientificamerican.com/eye-of-the-storm/earths-40-billion-dollar-weather-disasters-of-2019-4th-most-billion-dollar-events-on-record/) in economic losses in 2019 alone.
Floodwaters often rise quickly and with little warning, leaving people to fend for themselves as emergency response teams navigate the murky, rushing water. New Internet of Things (IoT) solutions provide real-time data and insight to detect potential flooding concerns to minimize risk to life, property and business.
### Flooding Is Incredibly Dangerous
Rising waters often flood quickly, leaving very little, if any, time to respond. Coastal areas have been decimated in minutes.
Jim Gray, CEO of Green Stream shared, “In many coastal towns and communities, rising water as a result of tides or rain can present a large threat.” Unfortunately, that threat is predicted to double by 2030 as issues associated with climate change compound and more people move to those densely populated areas.
### Loss of Life
Of all the destruction associated with floods, loss of life is often the hardest to cope with. Even one life lost is simply too much.
When flood onset is sudden many people find themselves stranded as their homes or cars quickly fill with water. Some are even killed in their sleep. Those with limited mobility are at an increased danger and emergency response help can’t always get to everyone quickly enough.
Even relatively shallow floodwater poses risks of electrocution by downed power lines and swiftly moving water can knock anyone off their feet. A person can drown in just a few inches of water if they are unable to get up quickly.
### Building Damage
Most buildings, especially in areas prone to flooding, are built to handle some water, but standing water is never good for a structure.
Water can significantly damage a building’s foundation and supports, requiring immediate repairs. Any equipment or machinery stored at ground level may also be destroyed. And, once the waters subside, mold and mildew take their place causing further damage and expensive cleanup.
### Commerce Impacts
Building damage alone can significantly hurt a business, but floods cause a lot of other problems. Merchandise may be lost both in the warehouse and in transit. Vehicles, computers, machines, files, and data storage devices can all be destroyed by exposure to water.
Flooding can make it difficult for employees to get to work or keep employees barred from the building until the insurance company finishes its assessment of the damage. And, customers are not always willing to understand flood-related delays.
### Sanitation Issues
If all the above weren’t enough, floods cause serious sanitation problems to people, animals, buildings and the environment. Waterborne diseases spread quickly in a flood. Rising water can carry human, animal, industrial, medical and hazardous waste, contaminating a whole city in minutes. Polluted water may cause gastrointestinal problems, tetanus, rashes, and can be deadly to those with open wounds. Even without dangerous materials floating around, water draws mosquitoes and grows bacteria the longer it sits in a building or city street.
### IoT Detects Floods to Minimize Risk
Pairing long range, low power sensors such as those with LoRa® device connectivity with smart IoT applications empowers experts to continuously calculate and track water levels and depths in real time. The small sensors can be installed in hard-to-reach areas like basements, alleys and sewers to remotely track water and immediately alert teams if levels begin to rise.
IoT flood management solutions protect people, structures and systems from environmental dangers. Using the real-time data, leaders are able to build more prepared and resilient communities and minimize risk.
The sensor data can also be integrated with consumer apps to alert residents of potential danger and provide needed resources like evacuation area lists and personal safety measures. And, while Wi-Fi may go down during flooding emergencies, LoRa, the de facto platform for IoT, prevails.

### LoRa and IoT Make Our World a Better Place
IoT solutions paired with LoRa devices make it possible to remotely measure and detect issues before they become a crisis.
Individual sensors with LoRa are networked through LoRaWAN® gateways to continuously collect data, allowing IoT solutions to analyze the situation and provide actionable insights. Since LoRa devices demand extremely low power, devices can be battery-powered for years and connect to the network wirelessly to remain in the environment without the need for maintenance. While we don’t have the power to stop floods, we can stop their damage by building proactive solutions and improving infrastructure.
LoRa devices are used in numerous environmental use cases including monitoring air quality, protecting endangered species, detecting gas leaks and [monitoring groundwater](https://www.semtech.com/company/press/semtech-lora-technology-used-by-trimble-for-iot-water-monitoring-sensor-series) systems to effectively address shortages. LoRa devices have even been leveraged by [Beartooth](https://beartooth.com/) to enable [reliable communication](https://www.semtech.com/company/press/beartooth-and-semtech-rsquos-lora-technology-provides-reliable-communication-in-cellular-outages) during cellular outages common during natural disasters.
The opportunities of LoRa and IoT are endless.
