DESCRIPTION:I will discuss both laboratory experiments and a n
 ewly developed theory for randomized surface waves
  propagating over variable bathymetry. The experim
 ents show that an abrupt depth change can qualitat
 ively alter wave statistics\, transforming an init
 ially Gaussian wave field into a highly skewed one
 . In our experiments\, the probability of a rogue 
 wave can increase by a factor of 50 compared to wh
 at would be expected from normal statistics. I wil
 l discuss a theoretical framework based on dynamic
 al and statistical analysis of the truncated KdV e
 quations. This theory accurately captures many key
  features of the experiments\, such as the skewed 
 outgoing wave distributions and the associated exc
 itation of higher frequencies in the spectrum.<br>
