Define Flood Warning System
Overview of Flood Warning Systems
Flooding from heavy rain, melting snow, and high water is a constant threat to life. It disrupts cities and risks community safety. Low-lying areas or those near rivers and lakes are especially vulnerable to these events.
To reduce these dangers, it is important to set up flood warning systems near big rivers. These systems help communities and transport networks get ready for floods. They save lives and protect property with quick and accurate warnings.
People around the world pay close attention to flood warning systems. In 1854, France created the first flood warning system along the Seine River.
The United States improved flood control on the Mississippi River in 1966. They used remote sensing technology to gather and analyze data. Today, many developed countries use automated flood warning systems on different rivers. Some developing nations have also set up similar systems in certain areas.
What is a Flood Warning System?
Engineers create a flood warning system. This system checks water levels and warns authorities about changes. It helps lessen damage from bad weather.
It also improves our water management.
The system gathers, sends, processes, and analyzes data on water levels. This helps predict floods accurately.
Advanced technology drives these systems. They use IoT (Internet of Things), sensors, databases, communication tools, and computer algorithms. Monitoring rainfall and water levels in real-time helps cut down property damage. It also saves lives by providing early warnings about possible areal flooding will occur.
Key parts of real-time flood monitoring systems are:
– **Sensors**: Liquid level sensors and weather sensors to gather data.
– **Communication Equipment**: Devices that send data, either wired or wireless.
– **Data Processing Tools**: Software used to collect, store, manage, and analyze information about floods.
Key Types of Flood Warning Systems
1. **Road Flood Warning System**
The national weather service road flood warning setup uses embedded water sensors to track groundwater depth in low-lying urban areas. When water levels go above a set limit, the system sends alerts. This notifies staff to fix drainage problems. It also warns pedestrians and drivers about dangerous water depths.
**Functions and Benefits**:
– Checks for water buildup in places like underpasses, bridges, tunnels, intersections, and overpasses.
– It keeps pedestrians and drivers safe by sending real-time alerts through connected stations.
– Helps with urban drainage by giving accurate data for managing waterlogging in the city.
**Applications**:
– These systems are set up in places like irrigation canals, rivers, drainage outlets, underground garages, and public transport hubs. This keeps people safe and protects property during bad weather.
**System Components**:
The road flood advisory monitoring station typically involves:
– **Sensors**: LORA-based buried water sensors and rain gauges.
– **Infrastructure**: Main stations with LED screens, alarms, telemetry tools, waterproof cases, and support structures like poles.
– **Cloud Platform**: A central platform for monitoring the environment. It helps with data integration and decision-making.
**LORA Buried Water Sensor**
This advanced measuring unit has a strong 304 stainless steel shell. It includes a water level detection module to check water depth and status. It also has a Bluetooth module, a LORA wireless communication module, and a rechargeable lithium battery.
Using liquid-based ultrasonic sensor technology, it measures how long ultrasonic waves take to go from sending to receiving. The system measures sound speed and time differences. It looks at how long it takes for sound waves to hit the water and for someone to hear the echoes. This helps the system accurately find the liquid level at set measuring points.
**Rain Gauge**
The tipping bucket rain gauge is a common tool in flood monitoring stations. It is known for its accurate measurements and simple installation.
Engineers create it for outdoor use over a long time. Installers often put it in open spaces to measure rainfall clearly. This device gathers rainfall data from the environment. It provides important help for flood warning systems.
**LCD Display Screen**
This screen has a 102cm x 22cm LED display. It shows two colors: red and green.
The display has a dot matrix of 16 x 96, set up vertically. This design makes it easier to see in tunnels, highways, and similar areas. It helps both people and vehicles see water depth levels clearly.
2.**Speaker and Alarm System**
The alarm and speaker stay off until the water level goes above set limits. When it exceeds the limit, the speaker plays messages that match the shown data and turns on the alarm. This warning system sends out three alerts every five seconds. It checks again to see if the limit is still exceeded.
**Telemetry Module**
This telemetry unit is in a waterproof case. It works as a special transfer server. This device lets you monitor things from afar. It sends real-time data on water levels and power status. It connects using a 4G module or RJ45.
**Waterproof Box**
The box is made from strong sheet metal. It is covered with a white plastic spray that resists rust. This waterproof box protects against bad weather. It can withstand long exposure to rain, snow, and bright sunlight. The durable housing keeps the inside stable. This allows for reliable outdoor performance over long periods.
**Pole Structure**
Made from strong stainless steel, the pole supports other parts.
**Data Platform**
The Flood Monitoring Station has a new system for collecting and managing data. It allows for monitoring all day, every day. You can access it through a website.
It helps you see trends in real-time or in graphs. It also lets you control things from a distance and aids in decision-making. The system sends alerts by text or email when data goes beyond set limits.
**Advantages**
1. **Wide Measurement Range:**
The telemetry unit can connect to 32 water sensors at the same time. This allows data collection from many places in the city. This “one-to-many supervision model” allows extensive coverage for water level monitoring in real-time.
2. **Flood Warnings with Long Transmission Distance:**
Before, checking water levels meant visiting many places in person. LoRa wireless technology allows users to send data up to 1,000 meters without wires. Its strong signal can easily pass through obstacles, ensuring good communication between measuring points and displays.
3. **Simple Bluetooth Configuration:**
You can set up on-site sensors using Bluetooth. Just rotate a magnet three or more times clockwise around the Teflon casing.
The configuration software helps users connect devices easily. It allows them to change settings like transmission frequency and data upload time. Users can also adjust the water immersion level and system time. They can see real-time water level data too.
4. **Remote Data Access:**
Telemetry sends water level data and battery status to the monitoring platform. This lets you access it instantly on your phone or computer.
The platform offers many features. These include real-time monitoring, remote alarms, and historical data export.
Users can change settings, see maps, and watch live video feeds. Other features include big-screen displays, user permissions, sharing information, and scheduled controls (manual, timed, or automatic).
**Multiple Alarm Methods for Enhanced Safety**
You can set safety thresholds for water levels on both the sensor and the monitoring platform. If the water at a site goes above the set value, the system will automatically trigger alarms.
– **On-site Alerts**:
The LED two-color display changes its font color to red. It shows the current water level in real-time. At the same time, sound and light alarms alert nearby pedestrians. Loudspeakers help to prioritize safety.
– **Monitoring Platform Alerts**:
The monitoring interface shows alerts. It uses visual cues like red colors. There are pop-up messages and sound alerts too.
Different channels, such as emails, text messages, or phone calls, send remote alarms. An electronic map shows the exact alarm locati0n. This helps responders act quickly and reduces possible losses.
**River Flood Warning System**
This flash flood warning is issued system tracks changes in river and water levels to predict possible flood damage. It is built to work well in tough conditions are favorable for flooding.
The system has protective features such as lightning protection and anti-jamming technology. It also includes derating and electromagnetic compatibility. Outlier elimination helps improve its strength.
These features help the monitoring station work well in tough environments. They protect lives and property.
