A study on flood risk assessment for Bandar Segamat sustainability using remote sensing and GIS approach

Abstract

Flood is one of the natural disaster usually take place that in the southern states of Malaysia such as Johor, Pahang and Malacca during rainy season. The number of area affected from this event has increase over the past years. This paper describes a study made to explore the application of GIS and Remote Sensing in flood risk assessment for Bandar Segamat sustainability. The objective is to explore and understand the flood risk assessment characteristics, Remote Sensing (RS) and Geographic Information System (GIS). Open source software such as QuantimGIS and Infoworks RS is used as tools in processing the data. The result show a significant movement of water in Segamat city which causing such loss in terms of property damages and lives. A simulation of flood risk and sustainability at Bandar Segamat was developed which indicate the most, moderate and less affected area in Segamat. The main contribution of the study was to prove that anyone that involved directly or indirectly in GIS or RS field are able to perform the similar study without the need of high cost, great experience and with basic knowledge of the field study.
