The flood frequency assessment is a very important parameter for water resource management. Every pre-monsoonperiod the analytical evaluations help to streamline the water management in monsoon. So the selection of an appropriateprobability distribution for describing flood frequency at a particular site is the governing criteria for assessment, highlighting theneed for an optimum solution. This paper highlights the scope of a mathematical model or statistical tool and it’s softwareapplications, to give optimum results for the appropriate method of flood frequency. Highlighting these aspects will surelyaccelerate decision making and help the authority to achieve optimization on the site. The objective of the paper is to discuss thepermutations and combinations of a particular parameter with one specific method as per the various field conditions andrequirements of the authorities.
