What are the different types of flood detection system?
There are two types of flood alarms: active and passive. Passive alarms are usually placed on the floor near appliances. They have flooding sensors that are water sensitive. Once they become wet, a signal is sent to the alarm panel and the alarm sounds.

What is flood monitoring and alerting system?
The purpose of this project is to sense the water level in river beds and check if they are in normal condition. If they reach beyond the limit, then it alerts people through LED signals and buzzer sound. Also it alerts people through Sms and Emails alerts when the water level reaches beyond the limit.

What sensors for flood detection?
These sensors used are the rain gauge, float switch, and flow rate meter sensor. It measures two of the important parameters in flood detection namely precipitation rate (mm/hr), flood level (ft), and the flow rate (L/hr).

What is the flood detection system using IoT?
The function of LCD and LED are to display and indicate the level of water. Based on flowchart in Figure 4, Smart IoT Flood Monitoring System is developed to alert the public closest to the area when there is upcoming flood. The process is starting when ultrasonic sensor measures level of water in the river.

What is the intensity of a flood?
Intensity is the rate of rainfall, and duration is how long the rain lasts. Topography, soil conditions, and ground cover also play important roles. Most flash flooding is caused by slow-moving thunderstorms, thunderstorms repeatedly moving over the same area, or heavy rains from hurricanes and tropical storms.

What is the frequency of flood?
Flood frequency means the probability of a flood occurrence which is determined from statistical analyses. The frequency of a particular flood event is usually expressed as occurring, on the average, once in a specified number of years or as a percent chance of occurring in any given year.
