Initial report on dust lifting and aggregation models

Initial report on dust lifting and aggregation modelsDust lifting depends on a number of parameters like grain size shear stress atmospheric pressure and gravity A model for lifting of sand and dust size grains will be worked out starting from an initial state of the art model modified by results of the projects Dust and sand lifted or suspended after the splash of a wind blown particle encounter other particles before the impact again or are resuspended for long time Especially dust grows to larger aggregates by hitandstick collisions The growth process is unknownThis initial report includes the description of the state of the art equations for lifting thresholds and aggregation properties
