Design of a flood monitoring and detection system for Unyama river in Amuru district.

Abstract

This project research report is about Design of a flood Monitoring and Detection System for river Unyama. Flood being a natural disaster, can't be prevented but its impact can be reduced. River Unyama has been massively flooding year after year ever since l3th May 2009 causing massive destruction of both lives and property. This work is presented in chapter form, Chapter one is composed of the introduction to the research problem. Chapter two contains a review of literature which has been produced by other scholars and researchers about monitoring and detection systems. The third chapter presents the various methods which were employed to achieve the objectives; amongst them were; to generate the hydrological model of the catchment which was, generated using ArcGIS, HEC Geo HMS and HEC-HMS software to develop the ‘hydraulic model of river Unyama which was done using HEC-RAS software, and to design and assemble the components that makeup the system and build its prototype model where Python, JavaScript, HTML, CSS and SQL were used. The Fourth chapter presents the findings, from the research and also bears the design analysis of the system like determining, sizing and selecting the components, of the system. It further contains, the reliability determination. In conclusion, the study was able to determine achievable flood mitigation measures, design a highly reliable flood monitoring and detection system with a working prototype model.

The main purposes of the research are to serve 1) as information channel for flooding warning When conditions exceed present thresholds and2), as a web based information source for the public, responding to their need for information on water condition and flooding. The developed system is composed of three major components: sensor network, This research was developed by using Raspberry pi'3 model B ++ microcontroller using the concept of the ultrasonic waves and groove water sensor.
