Abstract

The river mouth bars are shallow and dynamic barriers between the river and the sea. Morphology and morphometry of the river mouth bars depend on water and sediment runoff of the river or the delta channel, wave energy, depth and slope of the nearshore, tides, storm surges, ice regime, artificial measures. The paper deals with the developing of 1D model of movement of river mouth bar along the sea bottom of fixed slope.
