Outline of Final Research Achievements	Physical snow and ice modeling methods were developed to predict snow accumulation in built-up areas with high accuracy. In particular, the accuracy was improved based on detailed comparison and validation with observation results conducted by the applicant themselve. The model also incorporates snow weight predictions based on a heat balance model, which is a major feature of this method. Furthermore, in order to apply the developed physical snow and ice modeling simulation to a real city, the model was incorporated into an open source software and improved to handle a 3D city model that is being developed and released by the Ministry of Land, Infrastructure, Transport and Tourism. It was confirmed that the developed simulation model can be used to study effective methods of controlling snow accumulation in complex urban architectural spaces.
