Abstract

.Interaction between freshwater supply and wave activity is described in relation to delta formation associated with ephemeral Greek rivers, discharging into tideless ambient waters. The controlling variables are investigated using the discharge effectiveness index (E f), as applied elsewhere to worldwide large river systems.E f values differ in magnitude for large- and small-scale river/delta systems, characterized by analogous shoreline configurations (i.e., fluvially or wave-dominated). Seasonal fluctuations in river input and wave energy control the evolution of the small systems. High sediment fluxes, related to flood events, are also of fundamental importance to delta evolution.
