Abstract
The nonlinear dynamics of one-dimensional systems of hydrodynamic type is examined based on the Lagrangian description. The formation of essentially nonlinear, time-dependent structures within a compressible advection problem is considered. The conditions leading to formation of new regular as well as singular collapse-type structures and wavelet structures in the density profile are derived.
