The content of research problem is collection, synthesis, and analysis of the process, norm, software, documents, data and the actual projects at home and aboard. Since then suggested the following issues: General way, scientific methodology, the basic problems, has invested much effort to exploit and use professionally powerful calculation software for kind of cofferdam by bulk material: cofferdam in the shipyard, border dike protects port (breakwater, preventing sand, preventing sand - reducing sand...). Details are presented in the topic science research code: B2007-03-30- TD. Has been giving instructions, building algorithms and is the premise to come to build the specialized computer program automated to design cofferdam by bulk materials in building projects of port and waterway.
