    Recently, there has been considerable interest in the scaling behaviors of interfaces in physical systems with quenched disorder. We explore many facets of the spatiotemporal intermittent behavior at the depinning transition of the system. By using the scaling argument, we are able to express various scaling exponents in terms of the fundamental exponents. Our simulation also gives very good agreement with the prediction. Furthermore, the super-rough nature of the system motivates us to systematically investigate the correlation functions and thus, for the first time, extend the applicability of anomalous dynamic scaling ansatz on the systems with quenched disorder. Moreover, we also classify the super-rough interfaces into two main categories: one with global grooves, the other with local grooves. The direction for future research will be to investigate the crossover behavior of the model beyond criticality, which is believed to show some novel interplay between quenched and annealed disorder.
