Submarine slides have become serious and complex problems in the marine field. This is because, in the form of geo- hazard causing damage to the seabed environment in general and to the seabed facility constructed by humans as a means of sea based activities in the field of business, pipeline of oil and gas industry, and maintenance of the environment itself. This paper reports the implementation of laboratory experiment of submarine slide simulation. Results described in this document, leading to develop a method to estimate the velocity, the thickness, and the form of sliding mass based on the material properties such as density and viscosity which is the nature of the material rheology. The used scenario was the percentage variation of composition in the material model created as a mixture of water and kaolin. The slurry comprised only two materials those were kaolin at weight percentage of 10 to 35 with 5% increment, and water at the remaining percentage. Simulation results that density and viscosity make control to the movement of submarine slide. Higher density and viscosity mass will forms the shorter run-out distance. These results imply and give suggestion that laboratory model has similarity condition to the field in term of qualitative data.
