| Abstract: | At present, coastal erosion is a major problem all over the world. Limitations of traditional countermeasures put an importance to develop an alternative sustainable and eco-friendly methods for coastal erosion protection. As an alternative countermeasure, bio-stabilization approaches drawn substantial attention for the researcher around the world which included MICP (Microbial Induced Carbonate Precipitation) and EICP (Enzyme Induced Carbonate Precipitation) method. In the bio-stabilization technique as a consequence of bio-chemical reactions of urease enzyme calcium carbonate precipitated which act as a major cementing material in between the sand-soil particles and improve the physical properties of targeted materials (strength and stiffness). The objective of the research presented in this dissertation was to assess the viability of MICP and EICP technique as a novel alternative and effective countermeasures for the coastal erosion protection by distinguishing their mode of actions. Moreover, this study aimed to find out an appropriate or feasible conditions and methods that would be useful in making artificial beachrocks for coastal erosion protection in Greece and in Mediterranean countries, in an inexpensive, eco-friendly, and sustainable way. Natural jute fiber and watermelon seeds were also used as advanced bio-mediated technology in this study to increase the sample’s strength and durability. In future, the findings of this study could play an important source of information for commercial applications in protecting against coastal erosion and for other bio-engineering applications. |
