<p>Due to the rising number of incidents of bridge failure, scouring around bridges has received a lot of attention. Accurate scour depth prediction is a challenge for researchers and experts, despite massive global research efforts. Estimation the scour depth is crucial for both a safety and economy. Numerous factors affect the scour depth. In this work, the scour depth of three distinct pier geometries – circular, oblong, and rectangular – is thoroughly investigated, and the effect of water depth and discharge on the scour depth of a given geometry is evaluated. Three pier shapes were the subject of a total of 27 trials, nine of which combined three discharges with varying flume water depth. Experimental observation of scour depth shows good agreement with analytical and numerical scour depth values. A comparative examination of analytical, experimental, and numerical findings indicates that numerical models can effectively estimate scour depth, offering a cost-effective and time-saving methodology. Results showed that circular and oblong pier geometry shows lesser scour depth than rectangular pier geometry for a specific combination of flow depth and discharge. Scour depth decreased with increasing flume water depth for the same discharge. For the constant flume water depth, higher discharge results in greater scour depth.</p>
