The model itself runs smoothly however the model result seems no as good as I expected. The flow velocity in the vegetated area is quite similar as the flow velocity at the open channel (non-vegetated area), and velocity difference is only 0.5 cm/s. However, from the experimental data there is larger velocity difference between the vegetated flow and open channel flow, around 10 cm/s. It seems that the vegetation do not have a 'blocking effect' to slow down the flow in the Delft3D model. Can anyone help me with this problem? I attached my vegetation input file with this post also.<br /><br />By the way I also try to model the channel fully covered with vegetation, but the result is quite good and quite similar with the measurements. Thanks!<br /><br /><br />XiaohchenXiaochen Chen2016-11-02T04:50:59Z
