- Abstract:
- In order to systematically study the influence of the riparian construction models on the hydrodynamic characteristics of overland flow, the field scouring simulation experiments were carried out in the riparian zone of north Zhejiang Province. The variations of hydrodynamic parameters of overland flow such as flow velocity and runoff depth were determined at 6 construction models and 3 flow rates. The results show that the Reynolds number is less affected by the construction mode of the riparian zone, and it is more affected by the unit discharge; the riparian construction model and the flow rate have the significant influence on the Froude number, the flow velocity, and the resistance coefficient; the Froude number and the resistance coefficient will decrease as the flow rate increases, and the flow velocity is reversed; the riparian construction model can effectively improve the slope resistance coefficient; the engineering construction models are better than the pure vegetation construction models; the eco-concrete ball construction model is better in the two engineering construction models. These results can provide the theoretical basis for the ecological construction program of the riparian zone.
