Abstract
We recall Krichever's construction of additional flows to Benney's hie rarchy, attached to poles at finite distance of the Lax operator. Then we construct a 'dispersionful' analogue of this hierarchy, in which t he role of poles at finite distance is played by Miura fields. We conn ect this hierarchy with N-wave systems, and prove several facts about the latter (Lax representation, Chern-Simons-type Lagrangian, connecti on with Liouville equation, tau-functions).
