Аннотация:Results of field studies conducted in the Terek delta in 2002–2004 are presented. Seasonal vertical
deformations of the river bed in the lower course of the main branch (the Novyi Terek) are shown to vary within 0.5–1.3 m; intense development of the delta bar takes place. Regeneration of water streams that died away in the 1980s–1990s, and the formation of a new channel network in the lower part of Terek delta are recorded.
