Abstract

The Philippines is considered as a calamity-prone country due to its geographic location. It is where the Pampanga River situated. Part of the lower basin of the river affects the Municipality of San Simon, Pampanga through heavy flooding specially during rainy seasons. Currently, the Municipal Disaster Risk Reduction and Management Office (MDRRMO) does not have its own warning system except for the manual measurement of the Pampanga River water level in the area. This often results to pretermission to prepare the residents of San Simon, Pampanga from flooding. This study aims to develop a rainfall and river water level monitoring system which will be used as a basis for disaster preparedness. The researcher used the prototyping method in the stages of the development of the system. He used experimental method in testing the accuracy levels of the sensors used in rainfall and river water level measurements. A descriptive method was also used in determining the acceptability level of the respondents’ assessment to the developed system. The ultrasonic sensor used in the system for measuring the water level in the river got an accuracy of 0.9509. The measured accuracy level of the tipping bucket rain gauge which will be used in measuring the amount of rainfall for “Red Warning” classification was 0.8726. For the “Orange Warning” classification, it was 0.9451, and it was 0.9690 for the “Yellow Warning” classification. The respondents highly accepts that the developed system is functional and usable. They also accept that the system is reliable to be implemented as a basis for disaster preparedness in the Municipality of San Simon, Pampanga.
