| Abstract: | By using differential GPS,glacial moraines were measured in the Qilian Mountains,including Laolongwan valley,Ningchanhe valley in the eastern section,Bailanghe valley in the middle section and Laohugou valley in the western section.Then the morphology of moraines was simulated based on artificial neural networks in the MatLab software.The differences between simulated and measured elevations are less than 1 m and thus the simulated elevation is precise enough for the reconstruction of the moraine shapes.The... |
