The focus of the study in this paper is directed towards understanding the rate of reduction in bearing capacity after submergence is very much dependent on degree of saturation and respective c-  parameters. Also this study proposed the approach for calculating bearing capacity (qu) under submerged condition using actual values of c-  parameters by considering initial degree of saturation. The calculated values were verified (validate) with model studies by simulating field condition performed with isolated surface circular footing resting on c-  soil. The calculated values are well agreed with values obtained from model studies. In the study of model footing it is revealed that in case of degree of saturation greater than 85%, the reduction in the ultimate bearing capacity was 40% and in case of degree of saturation less than 85% the bearing capacity got reduced by 80% for the same soil
