This study focused on No. 1 Check Dam on Chijiawan creek in Taichung County, Taiwan, which was removed in May 2011 due to habitat restoration for landlocked salmon. We conducted scaled experiments on scenarios of different flood conditions, and removal sizes and shapes. We compared our experimental results of riverbed elevation profiles with the analytical solutions derived from the diffusion equation. Besides, we conducted the long profile survey after the dam was removed to compare with the experiment results. The findings indicated the experimental results fit better with the theoretical solution near the dam site when the simulated discharge was larger. The comparison between experimental and field longitudinal profiles suggest the experimental predictions provided solid information but also highlight discrepancies at some places.
