EWARNS™ web-launching on 30th March 2005 marked a proud moment for all Malaysians, being the first and premier free-to-public early warning systems website for Malaysia. It is hoped that with continuous research and development efforts, coupled with the establishment of various databases for Malaysian conditions and actual on-site verification, EWARNS™ will benefit the general public in line with the 'Malaysia Boleh' spirit! EWARNS™ early warning system on erosion risks / hazards utilizes a transmission unit, receiving unit and a display panel. The theory behind this system is that the transmission unit, also known as the Remote Sensing and Transmission Unit (RSTU), would sense the rain impact and transmit rainfall data at a regular interval via internet connections to a receiving unit. Subsequently, the receiving unit would read the e-mail, which contains the rainfall information, and then process the data together with the baseline database that is already made available. Results obtained would then be set against the threshold value to check the level of risk involved. Finally, the end result would be made available via an early warning system panel, which would be relayed to a website to make such information available to the public. This process would therefore be repeated at every few minutes if there were incidences of rainfall detected by the sensors. In this way, such information would be updated in a near real-time time frame in order to provide an early warning to the public and authorities concerned so that remedial actions and mitigation measures could be taken soonest possible once a high-risk area is detected by the system. Graphical interpretation of the EWARNS™ early warning system on erosion risks / hazards is as shown below.
The website's map of risk areas will also be updated every few minutes as data from the sensors are constantly calculated. A blinking red light with continuous playback of the warning sound indicates that certain area is at high-risk of erosion, while yellow is for medium, and blue for low-risk areas. Remarks on the percentage of risk area and in acreage for the built-up areas, roads and agricultural areas would also be shown in the display panel. SMS Alert notification will be given out at every 15-minute interval if there is any incidence of sudden weather change, which would be informative to the subscribers.

EWARNS™ (Early Warning And Risk Navigation Systems) is an innovative project by concerned Malaysian professionals who are dedicated to provide solutions of an early warning system or indication of possible threats from natural disasters to the environment. With the forecast and real-time indicators of risk levels, it is hoped that better management, co-ordination, and emergency response could be achieved to safeguard lives, properties and the environment.
