Effects of Configuration and Vegetation on the Mechanism of Water Exchange in Artificial Riverside Embayment

چکیده
Riverside embayment is expected to provide good habitat for fish in rivers. We measured flow field and water qualities at the artificial embayment zone in the experimental river of the Aquatic Restoration Research Center in order to investigate the mechanism of water exchange in riverside embayment. In a high water stage, flow structures near the embayment were revealed by the measurement. Vegetation on the downstream end of the entrance zone reduces the recirculating flow and this effect is well reproduced by the numerical model. In a normal water stage, the flow pattern in the embayment is affected by the configuration of the embayment. Laboratory experiments were conducted to make clear the effects of vegetation along the entrance of the embayment systematically.

Investigation of soil properties like Cation Exchange Capacity (CEC) plays important roles in study of environmental reaserches as the spatial and temporal variability of this property have been led to development of indirect methods in estimation of this soil characteristic. Pedotransfer functions (PTFs) provide an alternative by estimating soil parameters from more readily available soil data...

Unsteady dynamic behavior of TTCP model with different wrap around fin sets were investigated in a trisonic wind tunne. The aerodynamic coefficient force measurement in this wind tunnel shows good agreement in comparison with that of the NASA Langley Research Center in static case. The model was sinusoidally oscillated at three different frequencies of 1, 3 and 8 Hz at M=2.0 and the effects of ...
