Abstract: Flood frequency analysis is necessary for evaluating the flood peak which is used to provide the information about the probability of occurrence of an event for a particular return period. In the present study used the statistical approach for analysis the River Yamuna at Wazirabad, Indraprastha and Okhla Station in Delhi. The data had collected in form of maximum annual discharge from the Flood & Irrigation Department of Delhi from Year 1978 to 2017. So, its having the sets of observation now using the annual maximum series which is uni variant. Firstly, check the sets of observation that is time independent or not,than its decided that the discharge data is random or not which defines that our data is suitable for further computation. In this analysis adopting the method of moments which includes the various distribution i.e., Extreme value type I Distribution, Log EV type I Distribution, Normal Distribution, Log Normal Distribution, Pearson Type III Distribution, Log Pearson Type III Distribution. After that plotting the graphical representation for their distribution & their (95% confidence Limits which clearly seen in the graphical approach of the distribution). In each distribution tried to find out calculate the discharge for different return period 10,25, 50, 100, 200,500, 1000 years & also calculate the upper bound & lower bound discharges are calculated&coefficient of determination is also found which describes the scatter of observation is narrow. If the coefficient of determination is approaches to unity its means the distribution is less scatter, than comparing their results on the basis of D INDEX method which describes the best fit distribution method for River Yamuna at three barrage in Delhi.
