The Kaup-Broer hierarchy can be considered as a certain reduction of t
he KP hierarchy. Upon introducing the tau-function the Kaup-Broer syst
em can be formulated in trilinear form giving rise to Wronskian soluti
ons. In this paper several odes of the Painleve type obtained through
reductions of the Kaup-Broer system are considered. Those odes take a
trilinear form which allows a linearization.
