Experimental evaluation of two-layer air bubble curtains to prevent seawater intrusion into rivers

Ehsan Kahrizi, Seyed Ali Akbar Salehi Neyshabouri, Amin Zeynolabedin, et al.

Published: 2024-05-21
Subjects: Engineering

The seawater intrusion (SWI) into rivers can lead to many negative consequences, especially on agricultural activities and live ecosystems in upstream areas of rivers. One solution to prevent SWI is using air bubble curtains (ABCs). The objective of this study is to investigate the optimal location of ABCs and airflows. To this end, several tests with different flow and salinity rates were [...]
