AUTOMATED WATERLEVEL MONITORING USING REAL-TIME OBSERVATION (ALeRTO)

摘要

As the Philippines is geographically located near Pacific Ocean, episodes of natural phenomenon are undeniably present and these has brought devastation in the country. As a response to these events, the Philippine government encourages the mainstreaming of Disaster Risk Reduction and Management and Climate Change Adaptation (DRMM-CCA) initiatives to national and local programs. Several of the initiatives were the installation of Automated Rain Gauges (ARG) and Automated Water Level Sensors (AWLS) in flood prone areas. These sensors provide key information to government agencies such as the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAG-ASA) and PROJECT NOAH or the Philippines Nationwide Operational Assessment of Hazards, which are supposedly disseminated to the Local Government Units (LGUs) for them to be informed on an impending flooding in the area. However, it has been observed that these information and data are not directly accessible to local government units. As a preventive measure, the ADZU Phil LiDAR 1 has developed a system which aims to help the local authorities and communities along the flood-prone areas prepare for the adverse effects of floods by providing an early warning system which is capable of sending alert messages prior to flood events. The system retrieves data in the Water Level Monitoring Stations (WLMS) and Automated Rain Gauges (ARG) from the Advance Science and Technology Institute (ASTI). The Automated Waterlevel Monitoring Using Real-Time Observation (ALeRTO) device is programmed to monitor the ASTI website for critical water level and rain data, and interpret it into threshold categories which are: high, medium and low. As the device is programmed to identify water level threshold, it sends out alert messages via sms to registered users specifically to Local Government Units. Given this, the system will be able to expand the platform on disseminating information to two end-users, the LGUs and other government agencies (received via SMS) and at the same time to anyone who would access the website via the internet.
