Early Warning System is the provision for timely and effective information, which allows individuals exposed to hazards to take action, avoid or reduce risk to life and property and prepare for effective response. The basic idea behind Early Warning System is that, the earlier and more accurately we are able to predict potential risks associated with natural hazards esp. flood, the more likely we will be able to manage and mitigate the disasters’ impact on society, economy, and environment. Early Warning Systems help to reduce economic losses and mitigate the number of injuries or deaths from a disaster, by providing information that allows individuals and communities to protect their lives and properties.
The rapid growth of communication networks has made it possible for this process of data collection and analysis to be instant by making data available online and in real time. Real-time data collection and delivery is highly valuable in providing timely data needed to understand hydrological processes and most importantly during emergency situations where it can safeguard life and property.
