ABSTRACT
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 recording velocity distributions behind the building blocks under three upstream discharge ratios. The relationship between building blockage and flow pattern is determined as well as the pervious effect for wake flow characteristics behind the blocks. The obtained experiment data can be readily used to validate or calibrate numerical models for urban flood simulations.
