To test the applicability of ADV, two techniques (ADV and PIV) have been applied for simultaneous measurement of an open channel flow. Comparison of the results (time-averaged velocity, turbulence intensity, Reynolds stress, and power spectra) reveals significant difference in the performance of PIV and ADV. For the ADV measurement in particular, the sampling frequency exerts little influence on the...
This study presents experimental results of velocity distribution and water depth at specific locations obtained from simplified urban district experiments accounting for the effect of building blockage. Laboratory experiments are performed inside a flume (0.8m×0.8m×18m) for various arrangements of pervious and impervious building blocks. The Digital Particle Velocimetry System (DPIV) was used for...
