Determination of Dimensional and Shape Parameters of CRoss-sections of Natural Torrents in Small Mountain Watersheds

The aim of this article is to assess the accuracy of estimates of geometric and shape parameters in cross-sections of natural mountain torrents using the equations of regional downstream hydraulic geometry. Equations of regional hydraulic geometry were derived for 19 natural torrents of the Western...
