Implementation of Modern Developments in Precipitation Intensity Duration Frequency Curves (IDF) of Baden Wuerttemberg, Germany
Abstract
This research is intending to apply the latest advancements in precipitation IDF Curves of Baden Wuerttemberg (BW) as they play a crucial role in the hydrological engineering designs and practices. But the previous reliance of their constructions on empirical or semi-approaches makes it impossible to be feasible over the larger time scales and include simulations.
However, in view of the implemented methodology proposed by Koutsoyiannis (2021), these empirically derived IDF curves can now be extended to theoretically consistent stochastic models that ultimately enhance their applicability to the full range of time scales from minutes to years while simultaneously allowing the simulations for complex hydro-systems. Moreover, the use of the most advance and sophisticated statistical fitting method of K-moments for extremes not only effectively handles the bias due to temporal dependence but also gives the possibility of merging daily data to reduce any uncertainties associated with sub-daily records. The parameterization of the IDF model is the final outcome of this research whereas the precipitation intensity corresponding to various time scales and return periods is visually demonstrated. Hence, this non-parametric approach provides reliable at-site IDF estimates for the entire state of BW which may serve further as a valuable source for preventing storm waters and floods.- Publication:
