Journal of Hydrologic Engineering Special Collection on “Stochastic Methods for Analyzing Nonstationary Extreme Hydrologic Events” Call for Papers Current practices for designing hydraulic structures generally assume that extreme hydrologic events are stationary. But nonstationarity in hydrological records has been a growing concern because of the effect of various factors such as human intervention in river basins, low frequency climatic variability, and climate change due to increased greenhouse gases in the atmosphere. Many studies in recent decades have documented that in some places hydrological records exhibit some type of nonstationarity in the form of increasing or decreasing trends, upward or downward shifts, or a combination of them. Human intervention is one of the leading causes of changes in the hydrologic cycle of river basins. In addition, some of the “changes” in hydrological records may be due to the effect of natural climatic variability, particularly resulting from low frequency components of the climate system that causes decadal (e.g. Pacific Decadal Oscillation) and multidecadal oscillations (e.g. Atlantic Multidecadal Oscillation). Another reason for the growing attention to nonstationarity is the increasing greenhouse gases in the atmosphere, which may be causing changes to extreme precipitation, temperature, and floods in certain parts of the globe. While the significance of impacts on the hydrological cycle remains debatable and inconclusive some hydrologists suggest that nonstationary probabilistic models need to be identified and possibly used in some projects depending on the case. In addition, warming associated with climate change may be causing sea level rising globally and consequently increasing flooding due to storm surge in coastal regions and reduce the reliability of flood protection systems in coastal watersheds. Furthermore, climate change research suggests that the rainfall intensity associated with major tropical storms may also increase potentially leading to increased rainfall-induced flooding in areas exposed to such storms.
