The study and objective of this paper is to develop an early flood detection and warning systems as a public alerting system for possible imminent flood. The work is based on a previously conceptualized idea by the authors. The system focuses on monitoring the water level remotely using wired sensor network. Data is collected from the sensors using data acquisition device and channel to the control panels which then relay information to the public through Global System for Mobile Communication (GSM) using Short Message Service (SMS). It ensures that the end users receive appropriate warnings within suitable time interval to take effective action to save lives and minimize losses of property. The research work had been conducted in collaboration with Malaysia's Meteorological Department and Pahang Department of Irrigation and Drainage (JSP). Tests had been conducted and results are presented to verify the viability of our work. © 2009 WASET.ORG.
