In the framework of River Bank Filtration "RBF" applicability to confront Iraq water crises, this investigation was originated with the impartial of investigating its sustainability in Iraq. Principally, literature was reviewed in the field of RBF sustainability. 2 previous research results of a sampling campaign in November 2021, were implemented; Adnan et al. (2022a) and (2022b). They verified RBF applicability against Iraqi Standards and validated its applicability against International Standards, respectively. Accordingly, in this research, extensive fieldwork was executed, where site visits were carried out along Tigris River; the available wells were inspected and 5 sampling campaigns were undergone periodically, in December 2021, March 2022, April 2022, July 2022 and August 2022. This was achieved to consider Iraq seasonality. The samples result of the 5 campaigns were analyzed; plotted on graphs and compared to the results of Adnan et al. (2022a). The analyzed results and comparison emphasized the sustainability of RBF applicability in Iraq, which would, most probably contribute in solving its water conflict crisis.

In terms of the importance of enhancing concrete coastal structures exposed to chlorides, this study was initiated with the objective of increasing their lifespan. Two measures were proposed (i.e. to increase the thickness of the concrete cover oradd Carbon Fiber Reinforced Polymer (CFRB) sheets).27 R.C. specimens were investigated experimentally. The specimens were exposed to variable sodium chlorideratios by weight "salt cement ratio"(s/c) (i.e. 3:100 "3%", 3:50 "6%" and 1:10 "10%"). The specimens were prepared, cured, dried and tested. The Zagazig Structural Laboratory was set. Measuring devices were fixed and measurements were undertaken. Also, photos were captured and observations were documented. The strains, cracking load and cracking pattern were determined.The undertaken measurements, the shot photos and documented observations were analyzed; graphs relating the different parameters were plotted and were presented. It was found that these enhancement measures improved the behavior of the concrete specimens subjected to Chlorides which would most probably extend the lifespan of concrete coastal structures.
