Abstract (en)

The analysis of overgrowing of regulated stream slopes with woody vegetation shows that its distribution on ditch slopes is not uniform. The most favourable conditions for the majority of the species of woody vegetation are on the lower and middle thirds of a slope. At the existing density of woody vegetation (0.01 to 0.68 u.m-2) the roughness coefficient ranged from 0.030 to 0.045. In all investigated stream sections, when spring flood discharge probability is with 10 %, water overflow indicator is positive; the water depth in the bed (zV) of the natural reaches was lower than the depth of a regulated stream (hG). The reserve of hydraulic conductivity in the investigated Nemėža stream section is lost when roughness coefficient reaches 0.080.
