Abstract: Abstract Since The 1950s, Extreme Precipitation Frequency Has Increased And Produced More Rain In Many Parts Of The World. The Threat Of Flooding Is The Most Immediate Effect Of Heavy Rain. This Danger Is Magnified In Cities, Where Impermeable Pavements Compel Water To Flow Swiftly Into Sewer Systems. In This Study, The Extreme Value Type 1 (Gumbel), Normal, And Log-Pearson Type III Probability Distributions Have Been Utilized To Perform Flood Frequency Analysis On The Peak Annual Series Discharge Data Of 16 Stations At Johor State For The Water Years 2010 To 2020. The Predicted Design Floods For The Return Periods Of 2 Years, 5 Years, 10 Years,50 Years, 100 Years, And 1000 Years Were Obtained And Compared. Our Results Indicate That The Gumbel Type 3 Distribution Predicted Larger Discharge Values In Most Of The Stations.
