Hydraulic conditions of steady motion in an estuarial river section under wind influence

Meyer Z., Coufal R.

Archives of Hydro-Engineering and Environmental Mechanics

2001

Vol. 48, nr 3

59-83

The effect of wind influence upon swellings in river estuaries has been presented in this elaboration. The wind, which causes shear stresses at the water surface, changes the vertical profile of water flow velocity and therefore is a factor causing wind swell-ings. This problem is very important in the estuarial river sections, especialIy in river inflows to reservoirs (sea), when natural slopes of flowing water are smalI and com-ponents of gravity farce are not able to oppose the wind effect. Then wind backwater occurs.
