The Formation of Aufeis and Its Impact on Infrastructure around Ulaanbaatar, North-Central Mongolia
In this study aufeis features and their formation under natural conditions and in an urban surrounding in north-central Mongolia were investigated. Used methods included field observations, Electrical Resistivity Tomography (ERT) as well as analyses of satellite imagery and meteorological data. Aufe...
