<br />analysis approaches assume that flood magnitudes are independent and identically distributed <br />with time, Stationarity issues may be addressed by testing the sensitivity ofthe assumption on <br />flood frequency results and examining the causes of climate variability, Another issue is that <br />paleoflood data can provide incomplete records of large events because recent floods have <br />eroded evidence of smaller ones, This problem is usually minimized by using thresholds of <br />exceedance or nonexceedance, and sensitivity analysis, Generally, paleoflood hydrologic <br />techniques have been successfully applied throughout the western United States and several <br />other countries, <br /> <br />Completion of the Monograph <br /> <br />The Task Committee on Paleoflood Hydrology expects to have a first draft of the <br />monograph completed by the sununer of2000, The monograph will be reviewed by the task <br />committee and submitted to the EWRI Technical Committee on Surface Water Hydrology for <br />review and approvaL The draft monograph will then be peer reviewed by an independent <br />committee established by EWRI, The monograph is scheduled for completion and publication in <br />2001. <br /> <br />References <br /> <br />Baker, V,R" 1987, Paleoflood hydrology and extraordinary flood events, J, Hydrology, 96, nos, <br />1-4, pp, 79-99, <br />Cohn, T,A" W,L.
