This paper presents the results from a laboratory research project about water flow through and around coniferous and deciduous shrubs. These are the only two types of shrubs that were considered in this research project. The shrub obstruction consisted of natural branches fixed in the bed of the flume, transversly to the direction of the flow. Besides hydrodynamic parameters, shrub density, water swelling over them, and local drag coefficients of the shrubs was measured and calculated. The final measurement was influenced by the density of both shrub types mentioned above and the spatial orientation of their branches in specified shrub zones in the path of the flowing water. These were analyzed both quantitatively and qualitatively and the appropriate computational formulae were proposed.
