Abstract

Senate Report recorded last 2013 show that tropical storms and floods are the principal disasters with 102 and 72 occurrences, respectively. Distinctly, flood is still one of the biggest problems of the country. Statistics shows that 31.9% of the natural disasters, which occur in the Philippines in the years 1990-2014, are attributed to flood related episodes with a mortality rate of 5.9%. The researchers seek to approach non-structural measures to mitigate flooding problems of the country, specifically creating flood warning systems and to conduct several experiments testing the effectivity and efficiency of the flood warning system. This paper also aims to confront the century long problem of flooding and address the lack of real time flood warning system, thus reducing the loss of lives and damage to property; and to determine the effectiveness of the design of the river warning system in giving real time river water level updates. Results show that it works better if in contact with river waters than tap water. The device is audible in all distances at average ambient sound level of 50 to 60 decibels. Hence, the device is efficient in giving off sound alarms when deployed in different river systems.

Key words: River water level sensor, river flood warning system, river flood alarm system.
