Other Abstract



The height of debris flow head is a major parameter for prevention and treatment engineering reflecting the scale of debris flow. Steep terrain, massive loose material and rich water source are three major elements for debris flow initiation, and meanwhile, they are key factors for height of debris flow head. The relationship between height of debris flow head and graduation of bed sediment,flow or gradient is explored with homogeneous sand and wide grading of sand in test flume. The results show that the height of debris flow head rises at first and goes down with the increasing of flow, gradient, the mean grain size and the content of fine sand. Finally, the calculation model of debris flow head is established based on the concept of flow power and regression analysis method, and validated by other scientist's experimental data. The results above are significant for predicting scales for debris flow.
