小浪底水库降水冲刷物理模型试验大断面地形（2008年）

包含4组次高程数据。降水冲刷试验的初始地形是在2006年汛后库区实测地形上利用1978～1982水沙系列及拟定的水库调节方式逐步自然塑造而成。在库区淤积量约为32亿m3的初始地形条件下，进行两组不同洪水过程的降水冲刷试验，由此比较相同的初始地形，不同的来水来沙条件的冲刷效果。在库区淤积量约为42亿m3的初始地形条件下，进行两组相同洪水过程、不同坝前控制水位的降水冲刷试验，比较两者的冲刷效果及其出库水沙过程。

This dataset contains 4 sets of elevation data. The initial topography for the rainfall scouring experiments was gradually constructed based on the surveyed reservoir area topography after the 2006 flood season, using the 1978–1982 water and sediment series and preset reservoir operation schemes to simulate natural morphological evolution. Under the initial topography with a reservoir sedimentation volume of approximately 3.2 billion m³, two groups of rainfall scouring experiments with different flood hydrographs were conducted to compare the scouring effects under the same initial topography but varying inflow water and sediment conditions. Under the initial topography with a reservoir sedimentation volume of approximately 4.2 billion m³, two groups of rainfall scouring experiments with the same flood hydrographs but different pre-dam controlled water levels were carried out, and their scouring effects and outflow water and sediment processes were compared.
