description: The subject of the graduate qualification work is âFlood risk modeling (using the example of the Republic of Sri Lanka)â. The work is devoted to modeling flood risks for the example of the Republic of Sri Lanka. The extreme statistics theory has been used to compute mathematical models by analyzing the changes of the annual maximum water level at three hydrometric stations in Kelani Ganga Nagalagam, Hanwella and Glencourse.
The research set the following goals: 
1. Develop mathematical models for flood risk assessment. 
2. Develop mathematical models to estimate of time intervals between flood events. 
3. Calculate the risk of the water level exceeding the threshold level and calculate and plot time intervals between flood events of each gauging station at particular critical water level. 
The extreme statistics theory has been adapted to solve problems of ensuring flood safety from spring floods. Information sources include the Ministry of Disaster Management, Irrigation department and Department of Metrology. Current approaches to risk assessment function development were improved by using the extreme value theory. The most suitable model from the extreme value theory was defined by the behavior of the probabilistic density function. 
These results can be used to develop hazard maps for the relevant areas as one of the criteria that must be taken into consideration when choosing the optimal site for construction. The main advantage of having these hazard maps is that people with less technical knowledge can easily understand the flood vulnerability of that area and contribute to minimizing flood damages.
