A Preliminary Experimental Study of Mitigating Coastal Erosion by Microbially Induced Carbonate Precipitation (MICP) Using Laboratory Microcosm
The preliminary experimental results of erosion tests conducted on untreated and Microbially Induced Calcite Precipitation (MICP) treated sandy slopes using a laboratory microcosm, simulating tidal cycles are presented in this paper. The slopes were made with sand blended with various proportions of marine clay. The extent of erosion has been assessed, based on the reduction in height of the soil slope model after subjecting to tidal cycles using laboratory microcosm. The majority of studies on the efficiency of MICP, according to the literature, have been done on sand slopes alone; sand combined with marine clay, both treated and untreated with MICP, has received less attention. It has been shown that the collapse of sand slopes is worsened by the presence of marine clay which is a common occurrence in field. It was observed that for the untreated 35˚ soil slopes, for normal coastal sand, the reduction in slope height was 2.5%, and that of the treated soil slope was 1.25%. In the untreated soil with 20% sand and 80% clay soil slopes, the reduction in slope height was 28%, and that of the treated soil slope was 9.3%. It is observed from the study that there is significant improvement in erosion reduction in the soil slopes on MICP treatment.
