The major objective of this study is to identify the flood severity level of the study area using GIS applications. By employing this map, safer habitation zones were established. Direct personal observation and face-to-face interview was done to gather the primary data and Disaster Management center reports, Census reports of Sri Lanka, images and published research reports were used as secondary data. The severity level of flooding in this area was analyzed using SRTM imagery in ArcGIS and overlaid on a Google Earth pro map. The findings of the study established that the highly affected area consisted of around 8.953003 sq·km, the moderately affected area was around 9.190781 sq·km and the lowly affected area was approximately 9.31039 sq·km within the study area. The major causes for flood disaster in this area are the lack of drainage systems in some potential flood regions, the low landscape, poorly maintained drainage systems and the geographical arrangement of the road network. By creating this map, the inhabitants will be aware of danger areas and can relocate accordingly [3, 5-9].
Natural disasters are extreme events that result in death or injury to humans, and damage or loss of valuable infrastructure and environment. Such horrible catastrophes affect the village of Maruthamunai in Ampara District. It is situated in the tropical zone. Maruthamunai routinely experiences floods, drought, tsunami and contiguous diseases. The study was undertaken to identify the effects, causes and the disaster management activities. We also prepared a disaster risk map for the Maruthamunai area to identify the affected zone. Several methods are used to analyze this study. These include qualitative and quantitative data that were analyzed using SPSS and Arc GIS application to produce the maps. The study clarified the effects of natural disasters and prepared disaster risk maps to identify safe places. Our work will help to minimize the effects of disaster and will also support better environmental practices to mitigate the problems.
