Study on the flow of water through non- submerged vegetation
Vegetation is an important feature of many rivers. Vegetation along rivers produces high resistance to flow and, as a result, has a large impact on water levels in rivers and lakes. This paper investigates the effects of instream-unsubmerged vegetation (such as the reed-similar Kalmus) on flow resistance and velocity distributions. Artificial vegetation is used in the experimental study to simulate the Acorus Calmus L. Experimental tests have shown that resistance depends strongly on vegetation density and that the Manning resistance coefficient varies with the depth of flow. A simplified model ...
