Abstract
To understand the vicious nature of extreme flood events for the most flood prone region of Ganga River Basin, this study uses 36 years (1980-2015) of flood records from Dartmouth Flood Observatory (DFO) and the Centre for Research on the Epidemiology of Disasters (CRED) Emergency Events Database (EM-DAT). Further, the Water Level (WL) data collected from Central Water Commission (CWC) for same period are utilized to compare with the data of DFO and EM-DAT to identify the major flood events recorded in the Middle Ganga Plain (MGP). The final dataset comprises of 15 attributes (parameters) and is prepared of identified 99 flood instances for statistical analysis. The descriptive statistical analysis is performed for the following parameters: severity class, flood duration in days, affected flood area, flood magnitude, total number of deaths, and total count of displaced people. The graphical representation of all selected parameters provides an insight of common flood events, which lie between ±95% confidence level and exclude the major events as outliers.
