Abstract
We explored the details of Karman vortex streets (KVS) induced by islands in the Hangzhou Bay using high resolution Chinese Gaofen-1 data and Landsat-8 data. Thirty images, including 15 images obtained by Wide-Field-View (WFV) sensor from Chinese Gaofen-1 and 15 images obtained by Operational Land Imager (OLI) aboard Landsat-8, were applied to retrieve Suspended Sediment Concentration (SSC) based on a prior model. The results show that: 1) The Karman vortex streets induced by small islands can be detected clearly by high resolution satellite data from the change of SSC. 2) The Karman vortex streets contain 3-5 subunits, and the further away from the island, the larger the scale of vortex streets. Generally, the length of the vortex street is between 1500 m and 9800 m.
