While ports are gateways to the country’s transportation networks, break- waters protect port entry channels into and out of the ports. Therefore, such structures require regular monitoring to keep the port functioning. This paper investigates the use of the Intermittent Small Baseline Subset (ISBAS) DInSAR technique to monitor the deformation and the stability for the western breakwater of Al-Faw Grand Port in the south of Iraq (the longest breakwater according to Guinness World Records). The preliminary results exposed by high and low resolution (ISBAS) analysis are presented using the Sentinel-1 SAR dataset from May 2017 to January 2019. The analysis of ISBAS results shows deformation, particularly in the northern part of the western breakwater while the rest are stable. The study shows that the low-resolution ISBAS method (suitable to monitor a natural surface) can give excellent results, highly comparable to high-resolution (convenient for the analysis of infrastructures) for monitoring large structural systems such as breakwater. This can provide crucial information on the potential of using the ISBAS technique (high and low-resolution) for long-term breakwater monitoring and give new insights into the behavior of the breakwater structure where other monitoring data are lacking.
