Abstract
Floods are major problems, and their coexistence poses a potent threat, which cannot be eradicated but has to be managed. Extreme affects untold numbers of people, taxing economies, disrupting food production, creating unrest, and prompting migrations. There is much more that can be done to understand the effects of floods, particularly to help protect the poorest and most vulnerable. This research was carried out in the affected area of Bhimdatta municipality and aimed to find out the flood event of 2013 and present the scenario done for flood disaster management. The primary data were collected by direct observation and key informant survey. Landsat images were downloaded from USGS websites, and secondary information was collected through previous research and articles. The data were analyzed by using ArcGIS. It was found that the flood had created a negligible impact on the forest, high impact on the river itself, and average impact on land. 0.13% of forests, 17.38% of land, and 82.48% of river bodies were affected by the flood of 2013. Different governmental and nongovernmental organizations played an effective role for flood disaster management.
Highlights
Floods are the most common natural disasters that affect the societies around the world
Flooding is new to the Terai district of Nepal. e rivers in Terai are covered with silt and eroded through the Siwalik Range, which raises the bed level of the river and increases the risk of floods [3]
Ward numbers 11, 12, and 13 were most affected by flood, and these wards were studied for ground and key informant survey. e population of Bhimdatta municipality was 104,444 according to the 2011 Central Bureau of Statistics Data. e precipitation on the Dipayal hydrological station was up to 210 mm during June 2013, and the river discharge was 550 cusec in the Mahakali Sharada Barrage station [12]
Summary
Floods are the most common natural disasters that affect the societies around the world. Floods have gained increasing global significance as a result of their destructive nature and for causing monetary and human losses [1]. Flooding is new to the Terai district of Nepal. E rivers in Terai are covered with silt and eroded through the Siwalik Range, which raises the bed level of the river and increases the risk of floods [3]. Of all the disasters reported in Nepal, floods are the most devastating in terms of the number of deaths that occur and the damage they cause. Nepal suffers a death of 300 people annually on an average only through floods [6]. Understanding the spatial change by flood and knowing disaster management practices will contribute to preparation of long-term disaster management plan
