This project aimed to design a system which can provide protection and avoid the risk of unusual and sudden flooding in order to save the life. The highlighted objectives of this system are: (a) It can detect 4 Levels of water: Level1- Normal, Level2- Warning, Level3- Pre-Emptive Evacuation and Level4- Critical (b) will alarm for unusual raise of water (c) will alarm for unusual velocity and flow rate speed (c) has real-time data (d) will SMS the activity of the river (water level, velocity and flow rate). The Experimental Development method was used in the study. The development of a prototype device was necessary for the demonstration and validation purposes. Results revealed that both the evaluators rating and the functionality test data agreed that the device works well and it always exhibits all the features being stated. The results of this study indicate that the device is effective in giving people an early warning whenever a flood is coming. The information given through text message was reliable and is dependable. It also supports the idea that the device can be installed in flood prone rivers provided that good quality materials and tools will be used for lifetime purposes.
