Abstract. We review one of the modern methods of deriving approximate equations for the propagation of water waves. Upon applying this to the full inviscid problem, a hierarchy of models appears. Remarkably, these appear to be ill-posed in Hadamard's classical sense. Similar results obtain for both shallow and deep water situations.

Some preliminary suggestions about how to counter this state of affairs will be discussed.
