<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 />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.
