Abstract
Recently hydraulics in open-channel flow with vegetated zone becomes important increasingly for river restoration. Vegetated zone can be regarded as a kind of porous region and momentum sink due to the form drag. Flows inside and outside vegetation zones bring about strong shear layer and cause momentum exchange and additional resistance between them. In this paper, the recent studies of numerical calculation on fully developed turbulent flow in open-channel with vegetation zone are outlined:(1) modeling of vegetation for river hydraulics, (2) flow over vegetation, (3) compound channel flow with vegetation, (4) flow with vegetation zone.
