Effects of Hurst-Kolmogorov Dynamics in Intensity-Duration-Frequency Curves
Abstract
Intensity-Duration-Frequency (IDF) curves present the relationship between rainfall intensity, duration and frequency, and are widely used for various hydrologic applications at a catchment scale. These curves require information about maximum rainfall intensity, where the rainfall process description is usually assumed to be stationary and short-term persistent. However, there is empirical and theoretical evidence that rainfall demonstrates long-term persistence behavior, else known as the Hurst-Kolmogorov Dynamics (HKD). Here, we study the IDF curves within the context of HKD using a massive 105-year long 10-min rainfall time series and benchmark experimentation to see how these curves change under HKD and under a zero or short-term persistent behavior.
