MEASURING THE COSEISMIC DISPLACEMENTS OF 2010 Ms7.1 Yushu EARTHQUAKE BY USING SAR AND HIGH RESOLUTION OPTICAL SATELLITE IMAGES

The drainage-divide stability provides new insights into both the river network evolution and the tectonic and/or climatic changes. Several methods have been proposed to determine the direction of drainage-divide migration. However, how to quantify the migration rate of drainage divides remains challenging. In this paper, we propose a new method to calculate the migration rate of drainage divides from high-resolution topographic data.
