DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

According to past reconnaissance reports on typhoons or floods, the failure of some collapse bridges could be resorted to debris accumulation. The debris increases the effective area of substructure components, which increase the hydraulic loads on the substructure of bridges. In addition, the debris also reduces the flow area and causes backwater upstream, which results in more severely scouring. The purposes of this research are to measure the hydraulic loads on piers and scouring depths of piers under different debris accumulation extents and flow velocities. Furthermore, the stabilities of piers are analyzed through short-term fast Fourier transform and fractal analyses for the ambient measurements of velocimeters. A series of small-scale single-pier models and full-bridge modes were conducted to examine the structural behaviors under different flood velocities and debris accumulation extents. The experimental results are then compared with those from numerical simulations and literature formulas. Our results demonstrate that the hydraulic loads and scouring depths of piers increase with increasing the flow velocities and debris accumulation. Moreover, the fundamental frequencies of piers from short-term fast Fourier transform decrease with increasing the scouring depths while the fractal dimension decreases dramatically before the pier is overturning.
