Abstract

Our previous contribution in this journal [3] presents author´s method of vertical average water flow velocitries vzi calculation, as well as its verification. This method for open linear streams assigned as a „method of corresponding wetting perimeter”. It was shown, that for rectangular shape of river bed cross section the curve of characteristics Δhi is an elipse. The paper presented here is the second part of an approach mentioned before. The advantage of the presented method is, that it allows to use known characteristics Δhi for rectangular cross-section of given depth h, at a slope i and roughness n for simple estimation of vertical water flow velocities vzi even for different depth, slopes and roughnes having differents strip widths Δb. This hypothesis needs verification of curves of characteristics Δhi applicability. Results of this approach verification have shown the simplicity and reliability of its application even for natural non-rectangular shapes of cross-sections. It seems to be reasonable to prepare curves of characteristics Δhi as well as water flow velocities vzi along vertical line for often used shapes of stream cross section.
