The research is focused on the integrated use of satellite remote sensing, Geographic Information System (GIS), and extensive field observation techniques for a better understanding impacts watershed characteristics hydrological processes floods. It aims to create methodology assessing flood hazards risk regional local scale so that protective measures can be designed. Floods have occurred in s...

In China’s Loess Plateau severe gully erosion (LPGE) region, the shoulder-line is most intuitive and unique manifestation of loess landform, which divides a landform into positive negative terrains (PNTs). The spatial combination model PNTs great significance for revealing evolution landform. This study modeled proposed Surface Nibble Degree (SND), new index that reflects comparison areas PNTs....

in this paper, we present an efficient method for determining the solution of the stochastic second kind volterra integral equations (svie) by using the taylor expansion method. this method transforms the svie to a linear stochastic ordinary differential equation which needs specified boundary conditions. for determining boundary conditions, we use the integration technique. this technique give...
