Plotting position for low flow frequency analysis at jempol river streamflow station

Low flow frequency analysis is an important technique for calculating the probability of river flow availability during crucial low flow seasons, such as drought. It is also useful to predict the low flow information of a river in volume and frequency for future planning and construction of water re...

Civil engineering (General) Low flow frequency analysis is an important technique for calculating the probability of river flow availability during crucial low flow seasons, such as drought.

The average recurrence interval (ARI) of 2-, 5-, 10-, 25-, 50-, and 100-year were determined based on 18 years of historical streamflow data.

It shows that the Gringorten formula tends to give higher estimation values up to 18% compared to the Weibull formula when the flow duration increase.
