The Use of MF-DFA Based on Multi-Fractal Theory in the Safety-Monitoring of Dam Seepage

Abstract:

To ensure dam safety monitoring prediction accuracy ,How to determine correlation between the sequence of the entire dam safety monitoring at different time-range is one of the key contents of dam safety monitoring research. The paper takes a dam for example using multiple fractal MF-DFA to remove trend monitoring fluctuations of the original sequence and calculates the scaling exponent annually comparing with the corresponding dam seepage hydrograph .The results verify the feasibility of multi-fractal MF-DFA in determining dam seepage to provide a basis for subsequent modeling calculation.
