O článku:
Vegetation growing in the water along streams has been the subject of several studies since it was recognized that it could have a significant impact on the water flow. It may increase resistance to flow and cause higher water levels. Also, it has an effect on the velocity profiles. The purpose of this paper is to investigate, and determine how aquatic vegetation influences flow resistance, water depth and discharge in the Malina stream at the Záhorská lowland area. Vegetation causes resistance to flow; it reduces flow velocities, discharge and increases water depth. Measurements performed during three years at this stream were used for an evaluation of vegetation impact on flow conditions. The Manning´s coefficient was used as one way of quantifying this impact. The results show variation of this parameter during the growing season.
